Abstract: Biodiesel is the Fatty Acid Alkyl Ester of vegetable oils produced through transesterification reaction. Immobilized pure lipase and Rhizopus oryzae was used as the catalyst for the conversion of Waste Cooking oil (WCO) into biodiesel using methanol as an acyl acceptor. Response surface methodology (RSM) was adopted to optimize the parameters such as temperature, time, oil to solvent ratio, enzyme concentration for lipase and pH, olive oil concentration, rpm for Rhizopus oryzae. A high conversion of 94.01 % was obtained through lipase catalyzed reaction at oil to solvent ratio of 1:3, enzyme concentration of 10 % at 30 ? C after 24 hrs. Similarly, a high conversion of 83.76 % was obtained at an optimum pH of 5.5, olive oil concentration 25 g/L and 150 rpm was obtained for Rhizopus oryzae. The lipase resulted in higher yield of biodiesel when compared to the Rhizopus oryzae. Thus the influential parameters were optimized using RSM.

Abstract: The marine source was collected from the coast of Cuddalore, Tamil Nadu and it was extracted with 30 % acetic acid solution and Tris Hcl buffer. The crude was centrifuged to precipitate and precipitated with Ammonium Sulphate. The attained precipitate was dialyzed with 3.0 kDa membrane using magnetic stirrer and retentates were collected. The antimicrobial activity assay of crude protein extracts of Marine invertebrate was tested against microorganisms by agar well plate method. The marine invertebrate species Mactra violaceae was found to respond to produce the antimicrobial activity against E.coli, S. aureus, and P. aeruginosa. Further the crude extract was fractionated by RP-HPLC C-18 with the gradient range of 5-95 % CAN in 0.1% TFA solution. Eight fractions were achieved and the faction eight (F8) were responded with good antimicrobial potency against E.coli, S. aureus and P.aeruginosa. On SDS-PAGE analysis dark band was obtained with 14 k Da compared to marker. The crude protein extract of Mactra violaceze was also characterized by FTIR. The crude protein content of Mactra vuilaceae was estimated by biuret method which gives concentration at 5001g/mL of sample.

Abstract: Protease is an economically important enzyme that is being used in many food industries, pharmaceuticals and manufacturing industries. Since protease has heavy demand commercially, its production reaps riches. Studies were made in different strains producing protease enzyme. We have made an attempt to extract protease from bacterial strains isolated from dairy effluents of Chennai region. Totally 6 dominant strains were isolated from dairy effluents of Chennai region. Totally 6 dominant strains were isolated from dairy effluents collected from AAvin milk factory of Pattaravakam, Madhavaram and Sholinganallur of Chennai. Since, milk and milk products contain major amount of casein, bacteria isolated from the dairy effluents are expected to produce more protease enzyme. Bacillus subtilis (MTCC No. 1790) was used as the control. We checked and compared the protease activities of isolated strains with the control. We found that Pseudomonas species were more potent in protease production than the other isolated bacterial strains and the control.

Abstract: The herbicide paraquat residues in Cassava field have been shown to cause adverse human health effects and soil degradation, leading to decreased crop productivity. Bioremediation is the effective way to solve this problem. This study focused on selecting soil bacteria that are capable to degrade paraquat. The 283 soil samples were collected from Cassava field in Nakhon Ratcha Sima provinces, because of paraquat is one of the most widely used chemical herbicides in this area. All 112 isolates have been isolated. Among them, there were 6 isolates tolerance to paraquat concentration 1 mM, including 4 and 2 strains of Clostridium spp. and Aeromonas spp., respectively. The isolates were further tested for their efficacy to degrade paraquat. The results showed that only two strains of Aeromonas spp. (strain NK 66 and NK 67) were able to degrade paraquat. It was found that levels of paraquat decreased to 4.9 ppm (24.36%) and 10.68 ppm (53.4%) after exposed to Aeromonas spp. strain NK 66 and NK67, respectively. Molecular Methods to Identify Aeromonas spp. strain NK 67 using PCR-amplified 16s rRNA genes sequencing were employed. Nucleotide sequence of 16S r RNA from Aeromonas spp.strain 67 was compared with nucleotide sequences from GenBank database by using BLAST program. The results showed that 99 % similar to 16s r RNA from A. veronii strain ATCC35624, according to the results of classification by Bergey ' s Manual of Systematic Bacteriology. Then it can be conclude that this bacteria is A. veronii NK67 (JN880412). This is the first report that A. veronii exhibited high efficiency to degrade paraquat which can be further applied for remediation of paraquat in contaminated areas and going for commercial production.

Abstract: Streptomyces sp. SSM 5670 with the ability to degrade a natural polymers, polyhydroxyalkanoates (IPHAs), showed a high activity of the extracellular poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) depolymerase when it was grown in a basal medium containing PHBV as the sole carbon source. The extracellular PHBV depolymerase of the organism could be purified to electrophoretic homogeneity by ion exchange column chromatography and gel filtration approximately 10.5-fold. The recovery of its activity was 20.5 %. The molecular mass of the PHBV depolymerase was estimated to be 24 kDa. The maximum activity was observed near pH 7.5 and 30? C, the activity was lost at temperatures above 45? C. This enzyme might be used to promote the degradation of PHBV products buried in soil, stabilized compost or other environments around room temperature.

Abstract: Bacteria producing extended-spectrum ?-lactamase (ESBL) among clinical isolates have been reported in many countries. However, data concerning the role of environmental contamination in the dissemination of (ESBL)-producing Enterobactericeae are currently lacking. In this context, the aim of this study was investigate and characterize Enterobacteriacea strains isolated from different places in a hospital and to determine the occurrence of extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae. The bacterial isolates were identified on the basis of standard cultural, morphological and biochemical characteristics. Antibiotic susceptibility of the isolates was tested by disk diffusion method. A total of 637 strains of Enterobacteriaceae were isolated between 2007-2012. Susceptibility study showed that the imipenem was the most active antibiotic against overall enterobacteria with resistance rate of 2.51 %, however the high resistance rates were observed to ampicilin (98.11 %) and cephalixin (78.65%). The prevalence of ESBL was 136 (21.35 %) and ESBL-producing strains were K.pneumoniae 66 (28.45%) E.coli 31 (25.41 %), S.marcescens 18 (19.15 %), K. oxytoca 9 (17.31 %), En.clocae 5 (5.43 %), C.freundii 04 (16 %) and P. mirabilis 03 (15 %). ESBL production was confirmed by double disk screening, combination disk method and E-test ESBL strip. All selected isolates harbored from one to four different plasmids with molecular sizes ranging from 5-170 kb. In general, most transconjugants acquired ceftazidime resistance by an ESBL gene encoded on the largest plasmid (>125 kb) found in the respective isolate. In addition, these transconjugants co-expressd other antibiotic resistance markers such as amikacin and ciprofloxacin.

Abstract: Earthworms are soil dwellers that have profound effects on soil ecosystem. Their feeding and burrowing activities help to incorporate soil particles with organic matter and redistribute them back into the soil through their casts. The casts produced enhance microbial activities in soil that promote nutrient cycling. This study was carried out to compare the population and distribution of aerobic cellulolytic bacteria in earthworm casts against surrounding soils across selected sites within the Imo State University main Campus, Owerri. Four Habitats (A, B, C and D) were selected, composite soil and cast samples were then collected and the level of cast production (gm-2) was determined. After analyzing some physicochemical properties of the samples, the total number of aerobic bacteria (in nutrient agar medium) and aerobic cellulolytic bacteria in (cellulose agar medium) were counted. Our results showed a higher casts production in Habitat A (15.30 ? 3.10 g-2) than in Habitat B(12.50 ? 3.60 g-2), followed by Habitat C (10.80 ? 4.20 g-2) and Habitat D (9.50 ? 2.30 g-2), respectively. Casts recorded higher pH values, moisture, organic matter, total N, P, K and Ca contents in all the study sites. Casts also exhibited higher number of total aerobic bacteria (TAB) and aerobic cellulolytic bacteria (ACB), and bacteria cellulolytic activity compared to the surrounding soils in all the study sites. However, the quality of cast (and soil) decreased across the study sites (from Habitat A to D). The study suggested that earthworm cast could improve the physicochemical as well as microbiological properties of soil.

Abstract: Studies were carried out on the occurrence of superficial fungal infections amongst some occupational groups in Nigeria. The occupational groups investigated included car-washers, dog breeders, local farmers, football players, hair-dressers and urban road-cleaners. The study was also extended to HIV/ AIDS patients. A total number of 13 species of fungi were isolated from both the occupational groups and the HIV/AIDS patients. The isolates included 4 species of Microsporum, 7 species of Trichophyton, 1 (one) species of Epidermophyton and one species of Cladosporium. A total of 10 species of fungi were isolated from the HIV/AIDS patients. It was observed that some of the test individuals abused some antibiotic drugs. Some of the infected individuals were found to share their residential homes with domestic animals. It appeared the dog breeders contracted their fungal infections from either the infected pregnant dogs or the infected male dogs. The fungal isolates from HIV/AIDS patients appeared to be opportunistic organisms that stemmed from immune suppressions. It is known that susceptibility to superficial fungus infection varies but the nature of this immunity still appears to be obscure. The details of the results obtained from study have been discussed.

Abstract: Du to worldwide phenomenon of microbial resistance to commonly used therapeutic agents, antibiotics and antifungals as well, a non-traditional series of perspective ultra-short acting ?-adrenoceptor blockers, labeled as 1-4, has been in vitro evaluated against selected Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacterial strains as well as against yeast (C.albicans) by the minimum inhibitory concentration(MIC) assay. From chemical viewpoint, the presence of polar carboxy group within the structure of tested compounds has not found to be favourable structural feature because of its supposed splitting by the enzymes which have been produced by all concerned microorganisms. On the other hand, within inspected set of the compounds, the increase in the lipophilicity has meant moderate improvement of the effectiveness against S. aureus and C. albicans, reaching the maximum for the most lipophilic substance 4 which has shown MIC=0.78 mg.mL-1 for given bacteria and yeast as well.

Abstract: Jawaharlal Nehru National Solar Mission (JNNSM) was launched in January 2010 and target for solar power was put at 20000 MW by 2022. This was uphill task at that time as the cost of solar PV system was Rs 220 per Wp. By 2012 the prices crashed to Rs 50 per MW & same daunting task started looking a modest one.
