Abstract: The aim of the present investigation was to document characteristics exhibited by the dairy wastewater generated by the organized and unorganized sector. Thirty samples were collected from each sector and analyzed for various pollution parameters as per standard procedures. The analysis of various parameters showed that the effluent generated from unorganized sector is richer in organic content as their C:N ratio (37.6) was over three times the C:N ratio for organized sector wastes (11.9). pH of dairy waste water generated by both the sectors varied between 3.0 to 8.3. 90 % of the samples drawn from unorganized sector were markedly acidic compared to only 56.6 % samples from the organized sector. In the unorganized sector average oil and grease content of samples was recorded as 1792.67 mg/L and for organized sector it was recorded as 919.33 mg/L. Total suspended solids ranged between 1000-15000 mg/L for unorganized sector and 500-3000 mg/L for organized sector. Average BOD3 of samples collected from organized sector which was 2196.61 mg/L. The results were analyzed statistically significant at 95 % confidence interval. There is limited information available about the characteristics of the effluent of the unorganized sector. Significant variations between major pollution parameters warrants different treatment approaches for effluents generated by these two sectors.

Abstract: In this study, the effect of hot water treatment on the adhesion force of Pseudomonas aeruginosa (MTCC2297) biofilm was studied using Atomic Force Microscopy. The adhesion force of four day old biofilm decreased from 11.6 ? 0.2nN after incubation in hot water for one day at 50?C. The adhesion force further decreased to 2.1? 0.1 nN after incubation in hot water for two days at 50?C. The results suggest that the adhesion force of biofilm may be reduced by incubating biofilm sample in hot water.

Abstract: Imidacloprid [1-(6-chloro-3-pyridylmethyl)-2nitroimino-imidazolidine] has gained great attention as a synthetic insecticide that acts in a similar manner as nicotine and is now widely used for the control of pests. Microorganisms respond to environmental or chemical stress by synthesizing specific sets of proteins that can be analyzed by protein profiling using SDS PAGE. The present investigation was undertaken to elucidate protein profile changes and differently expressed proteins in soil isolate Brevundimonas Sp.MJ 15 on dose and durational exposure to imidacloprid. Protein profiling of Brevundimonas Sp.MJ 15 treated with different (10-7 to 10-3 M) concentrations of imidacloprid observed regularly at the dutration of 24 hrs for a period of 96 hours, showed the over expressions of certain protein, expression of stress proteins and novel proteins. The proteins induced were observed to be dose and durational dependent. The present investigation proves that imidacloprid exposure induces the expression of stress and novel proteins in soil isolate Brevundimonas Sp.MJ 15 from toxic effects of exposure to imidacloprid. The specific protein profiles that are expressed in response to the stress induced by imidacloprid can be used to monitor the environmental samples for the presence of similar pollutants.

Abstract: Fermented fish products are popular in the North eastern parts of India because of their characteristics flavour and aroma. Tungtap is a fermented fish product prepared from Puntius and/or Danio spp. And consumed as pickle and taste enhancer by the khasi tribes of Meghalaya.The study was carried out to assess the quality parameters of market available Tungtap. The results of the analysis showed that the market sample of Tungtap was a good source of protein, lipid and ash, i.e.37.05%, 15.33% and 15.35% respectively but the biochemical parameters were found to be relatively higher. The microbial numbers were also relatively higher and the presence of Vibrio and E.coli indicates unhygienic processing or retailing. There were no visible fungal colonies on the product; however when grown on selective medium, a few fungal colonies were observed. But the product was safe from human consumption point of view.

Abstract: Cultural heritage assets are exposed to weather and submitted to influence of environmental parameters. Physicals, chemicals and biological factors interact with constitutive materials. The air contains a large amount of biological and a biotic component such as, pollen grains, fungal spores, insects, mites, fibers and dust particles but their number and concentration depend upon the geographical location, types of vegetation and meterological parameters. Fungal ability in producing pigments and organic acids have a crucial role in the discoloration and degradation of different types of stone in cultural heritage objects. Fungi are heterotrophic complex communities. They need organic matter for metabolism, thus produces pigments and organic acids. These acids are responsible for biodeterioration of various cultural objects. Additionally, stone objects may support the communities of microorganisms that are active in the biodeterioration process. Therefore, the aim of this paper is to summarize data on the fungal impact on biodeteroration processes. Present investigation focuses on mycobial survey of the Kamala raja girls college, Gwalior (M.P) and study carried out August 2013 to December 2014. During the investigation period 17 fungal species were isolated from the surface of monument. The fungal species isolated during the study are Aspergillus spp., Fusarium spp., Curvularia spp., Penicillium spp., Rhizopus spp., Rhodotorula spp., Candida spp. The most frequently isolated fungi belong to genus Aspergillus.

Abstract: A multiplex PCR (mPCR) targeting virulence gene (s) of Listeria spp. i.e, Internalin C (inlC), Internalin J (inlJ) and Listeriolysin O (hlyA) in case of Listeria monocytogenes and inl C in case of Listeria ivanovii was developed and evaluated on standard strains of Listeria spp. as well as isolates (25) of Listeria spp. with known biochemical and pathogenicity profiles based on other in vitro and in-vivo pathogenicity test with an ultimate view to evaluate this mPCR for raid and reliable identification and pathogenecity testing of listeria isolates was done. Out of many known virulence marker, listeriolysin-o encoded by hlyA gene is till date a well recognized one with few errors; here in this study InlC and inlJ genes were also studied in conjunction with hlyA to strengthen the existing hlyA marker. The mPCR showed presence of inlC gene in majority but not all virulent strains of pathogenic listeriae, however, it was also detected in some non-pathogenic L.monocytogenes strains. The same trend had been seen in, inlJ also, which revealed although these genes are linked to virulence but may not be an essential a full proof virulence marker for Listeria spp. However, its combination with other more specific virulence marker (s) need to be evaluated on known positive and negative Listeria strains with known pathogenecity profiles on a large number of Listeria isolates of various kind before drawing any final conclusion.

Abstract: Plants used in traditional medicienes are a promising source of bioactive compounds and some can potentially inhibit bacterial quorum sensing (QS ), a cell-cell signaling mechanism mediated by autoinducers to regulate a range of biological functions including virulence in bacteria. Inhibition of QS offers an alternative strategy for antibiotic mediated bactericidal/bacteristatic approach and believed to reduce the risk for development of resistance. The primary objective of this study was to investigate the anti-QS activity of inula racemosa Hook f., a member of the family asteraceae. Anti-QS activity of the ethanol extract of I. racemosa was determined by biosensor bioassay using Chromobacterium violaceum ATCC 12472 and swarming motility in Pseudomonas aeruginosa PA01 was also determined. The ethanol extract of I.racemosa showed anti-QS activity in biosensor bioassay as indicated by clear turbid halo zone of violacein inhibition in C. violaceum CV026 culture plates. It also showed inhibition of violacein production by more than 80 % in C. violaceum ATCC12472 at 1 mg/ mL concentration and complete inhibition of swarming motility in P.aeruginosa PA01 at 0.1 mg/mL concentration. Meanwhile, the growth of C. violaceum and P. aeruginosa PA01 was not affected significantly at all the tested concentration of I.racemosa ethanol extract. The ability of plants to produce substances that affect QS regulation provides with important tool to manipulate gene expression and control bacterial infections in humans.

Abstract: Seaweeds are the commercial source for the production of alginate, which I having a variety of applications. More precisely, they are used as viscosity enhances in food preparations and also in the field of biotechnology as good immobilizing substance for enzymes and proteins. The extraction of alginate causes considerable damage to ecology. The fish and marine life are interwoven to it in their habitat. Seaweeds are the bottom dweller of the food chain and they detoxify heavy metals such as cadmium and lead which will be a health concern if the products are manufactured out of it. Here we had isolated a soil dwelling microorganism found to be of Azobacter sp., which was potential enough to produce alginate. The parameters for the microbial production were optimized and the yield was significant after optimization. Temperature, pH, aeration and agitation of the fermentation medium were studied and optimized. The viscosity of the produced alginate of the fermentation medium were studied and optimized. The viscosity of the produced alginate was quiet appealing at all stages of the production. The strain yielded a maximum of 6.47 mg/mL of alginate. Microbial L-Glutaminase, an anticancer enzyme was selected for immobilization. The alginate produced was of good quality and the enzyme activity was steady for about 72 hours. The kinetics of the enzyme was studied using non-linear regression equation. Michelis Menten and lineweaver-burks plot were made. The enzyme Km and Vmax were found to be 459.2 mM and 1.383 mM/min respectively. The enzyme was found to have a high affinity towards its substrate.

Abstract: The major problem of wound management and therapy is bacterial infection and wound sepsis, which is worst case may, lead to mortality. Proper management of wound and successful wound healing requires the identity of colonizing bacteria and its sensitivity to antibiotics , as most of the pathogens have developed resistance to commonly used antibiotics. Hence, the present work is aimed to evaluate the prevalence, etiology and susceptibility pattern of bacterial pathogens isolated from diabetic wounds to commonly used antibiotics and silver nanoparticles. The sample was collected from Government Hospital in Aruppukkottai, Virudhunagar District, Tamilnadu, India. Silver Nanoparticles were synthesized using Murraya Koenigii. Out of 5 pathogenic isolates, predominant pathogen (3) was Pseudomonas aeurogenosa. Others were Enterobacter sp and Staphylococcus sp. Antimicrobial susceptibility test for isolates were executed using disk and well diffusion method. Pathogens were resistant to gentamycine, neomycine, cephalosporin, penicillin, metrogel, silvergel and ciprofloxacin. But sensitivity was intermediate to ciprofloxacin and susceptible to Silver Nano particles. Nano particles were characterized by XRD and FTIR. MIC of Silver nano particles (SNP) to the isolated P.aeruginosa ASM 100 was 1.5 mg/mL and MBC was 6mg/mL. So the present study reveals that Pseudomonas was highly resistant to most of the drugs used to treat infection. Susceptibility towards silver nano particles opens a window foe new wound dressing with SNP synthesized using edible leaf.

Abstract: Actinomycetes are gram positive bacteria comprising a group of unicellular microorganisms. Streptomyces is a well-known antibiotic producer. Marine actinomycetes have emerged as a rich source of novel compounds. Alkaline protease enzyme was isolated from Streptomycetes which has wide applications. In the present study, Streptomycetes were isolated from sediment samples collected from Mandapam coast, Gulf of Mannar and it was characterized. Antimicrobial activity was determined by disc diffusion method for the isolates MS-1 and MS-2 treated against human pathogens such as Salmonella, Klebsiella pneumonia, E.Coli and P. fluorescence. Ms-1 and MS-2 revelaed highest antibacterial alkaline protease activity compared to other isolates. Anti-inflammatory studies using mice model system were performed. The mice were treated with crude extracts of actinomycetes orally inorder to study anti-inflammation. It was found out that wihin 10 days the mice found to be cured from inflammation after oral supplementation of crude enzyme extract which indicated these bioactive compounds have analgesic properties.

Abstract: The effect of essential oil extracted from the clove (Scyzigum aromaticum), eucalyptus (Eucalyptus oblique), ginger (Zingiber officinale) and peppermint (Mentha piperita) were tested under in vitro condition for their inhibitory effect against twenty numbers of pathogenic fungi isolated from one year stored cowpea (Vigna unguiculata ) seeds at different concentrations (0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09 and 0.1 %)
The antifungal activities of the oils were assessed by evaluating the percentage of infected grains. It was recorded that tested oils showed inhibitory effect against the pathogenic storage fungi. The fungi were also responded to the concentration of the oil, i.e. high concentration showed high inhibition. The antifungal activity of the essential oils at 0.02, 0.04, 0.06, 0.08 and 0.1 % concentration was also studied under in vivo condition. Results showed that, application of these oils decreases the incidence of pathogenic storage fungi. It was recorded that, number of fungi appeared at 0.1 % concentration was significantly less. Among the essential oils. The strongest antifungal activity was exhibited by ginger oil.

Abstract: Conventionally in a water treatment plant fine suspended matter is made to agglomerate into larger size flocs by adding chemicals that neutralize the inherent negative charges on colloidal impurities that repel them from each other and interface with their settling mechanism. It is important that the exact dosage of the chemical (coagulant) is determined prior to addition, because if the dosage becomes more than the particles acquire net positive charge resulting in their repulsion from each other and non-settlement. In water treatment plant, optimum dose of coagulant is generally evaluated by jar test method. Limitation of this test is that it is time consuming, expensive, and the accuracy of results depends upon experience of the plant operator. Coagulant doses are often approximated, resulting in poor quality effluent from secondary settling tanks. In this study water samples were collected locally from different sources e.g. lake, river, village pond a canal. A review of the commonly available coagulants was made and Alum was identified as the potential coagulant for this study. Optimum alum dose tests were carried out on all samples and the results have been analyzed and presented in graphical format to give some idea to plant operator on the approximate values of optimum alum dosages for various sources of water in the region. It is hoped that this study shall reduce the time, effort and costs involved in finding the optimum alum dosages for these surface waters, because the operator can lay his/her hands on rough value as a starting point and then carry out the experimentation to refine his/her results. The study aims to reduce time, cost and effort in operation and maintenance of water treatment plants where turbidity values of the incoming water fluctuate dynamically with time, and offers a sustainable outcome to this issue.
