Abstract: The dairy industry involves processing raw milk into products such as consumer milk, butter, cheese, yogurt, condensed milk, dried milk (milk powder), and ice cream, using processes such as chilling, pasteurization, and homogenization. Typical by-products include buttermilk, whey, and their derivatives. Since the pollutants generated by the industry are largely lost in production, improvements in production efficiency are recommended to reduce pollutants loads. In this study, a series of experimental studies were conducted with regard to bioconversion of organic fraction of municipal solid waste along with dairy waste water at different C/N ratios using combined composting and vermicomposting technology. The variations in physical and chemical parameters were monitored throughout the process. The results indicate the combined composting and vermicomposting of dairy waste water with municipal solid waste produces high quality compost.

Keywords: Slurry fermentation, Bacillus subtilis, Rice bran, Phytase
Abstract: Phytase production profile of Bacillus subtilis was investigated here in submerged fermentation with and without enhanced level of fortification by powdered rice bran 9Slurry fermentation). Incorporation of rice bran as substrate particles (5% w/v) in nutrient broth resulted in 5. 11 times better yield of phytase when compared with un-supplemented broth. Among the different substrate particles introduced, rice bran was found to be inducing better phytase productivity. Substrate incorporation at varied concentrations (between 1%-15 % w/v) gave better phytase titers at 9% w/v (41.94 U/mL) of incorporation and 32 hrs of harvest. Acidic medium pH, addition of surfactants after sterilization and bioprocess carried out at 40 ? C were al found to have positive influence on the enzyme titers in the fermentation samples. Suitability of slurry fermentation for phytase production established. Higher enzyme activity at 40 ? C were all found to have positive influence on the enzyme titers in the fermentation samples. Suitability of slurry fermentation for phytase production established. Higher enzyme activity at 40 ? C were al found to have positive influence on the enzyme titers in the fermentation samples. Suitability of slurry fermentation for phytase production established. Higher enzyme activity at 40 ? C and acidic medium pH reiterate the suitability of this phytase as feed premix for poultry.

Keywords: L.reuteri, 1, 3-Propanediol, Fed-batch, Cell density, Product tolerance.
Abstract: There is an urgent need for the production of valuable chemicals like 1,3- Propanediol from glycerol, a waste product from biodiesel industry. Since 1, 3-Propanediol has biomedical and healthcare applications, it would be suitable to procedure it in an organism with wide acceptability like Lactobacillus reuti. However, lower cell density as well as reduced product titres seem to be the key factors limiting process development. To address these issues, a fed-batch strategy has been presented in the current study. A 4-fold increase in biomass and 25 % increase in biomass and 25 % increase in 1, 3-PD concentration could be achieved in fed-batch as compared to the batch mode of fermentation. Product tolerance assay has revealed that L. reuteri is capable of tolerating 100 g/L of 1,3Propanediol, indicating its potential for industrial application.

Keywords: Maize, Aflotoxins and PCR
Abstract: Maize (Zea mays L.) is one of the cereals which serves as a main source of food, forage and processed products for industry with a production of around 790 million tones. As a staple food it provides more than one-third of the calories and proteins in some countries. Aflatoxins are a group of chemicals produced by certain mold fungi such as Aspergillus flavus and Aspergillus parasiticus. Aflatoxins are harmful or fatal to livestock and human beings as they are carcinogenic. The present study was undertaken with the main aim of detecting the presence of these genes encoding the production of mycotoxin in the infected maize samples. One hundred and thirty maize samples infected with the fungi Aspergillus parasiticus and Aspergillus flavus were collected from the markets, godowns and farmers ' fields. DNA isolated from such maize samples was amplified in PCR using four sets of forward and reverse gene specific primers designed using DNASTAR Lasergene 8.0 version software from original gene sequences (obtained from GENBANK) of the specific gene, aflq. The fragments obtained were resolved on the bioanalyzer, DNA 1000 Labchip, for generating data on the size of amplified fragments. A 168 base pair fragment of aflq target sequence was amplified in twenty nine maize samples. This study helps in easy detection of mycotoxins present in the contaminated samples in storage which are unfit for consumption thereby avoiding the hazardous influence of such toxins on human and animal health.

Abstract: Present study attempted to detect the pathogenic load n export quality shrimp samples and to demonstrate the drug resistance traits of the pathogenic isolates. Samples were found to be contaminated with Listeria spp. (1.0 x 105 cfu/g), Staphylococcus aureus (9.1 x 106 cfu/g) and Escheria coli (1.0 x 103 cfu/g). Study of antibiogram revealed that Listeria spp. was resistant against penicillin G and ampicillin, S. aureus against trimethoprim, erythromycin, sulfamethoxazole, and Escherichia coli against erythromycin and polymixin B. However, all the isolates were found to be susceptible against tetracycline, and most of them also exhibited a greater degree of susceptibility towards amoxicillin, ceftriaxone, ciprofloxacine, streptomycin, chloramphenicol and cefixime. The antibacterial activity activity of the shrimp blend was also examined. Interestingly, the head and body portions of the shrimp samples exhibited antibacterial activity against Staphylococcus spp. and Listeria spp.

Abstract: Consumption of drinking water contaminated with focally originated pathogenic bacteria is mostly responsible for the onset of water borne diseases outbreaks especially in developing countries. Current study attempted to analyze 25 treated drinking water samples both qualitative-and quantitatively from different areas of Dhaka metropolis, Bangladesh where 90 % cases of diseases (dysentery, typhoid, Cholera and diarrhea) have long been reported due to the water borne microorganisms diseases. Through the most probable number (MPN) method, 5 samples out of 25 were found to be non-potable as they had been contaminated with Escherichia coli indicating the risk for fecal contamination responsible for diseases outbreaks. Other contaminating Gram negative bacteria were characterized as Klebsiella spp, Alcaligenes faecalis, Pseudomonas spp. and Aeromonas spp. Intrestingly the presence of E.coli was detected in the same 5 samples within a range of 3.0 x 102 to 1.7 x 105 cfu/ml by the conventional cultural and biochemical methods. Moreover, a huge array of other pathogenic bacteria was also detected (5.0 x 102 -3.5 x 108 cfu/mL) through this method. Further detection of drug resistance traits among the bacterial isolates would be of public health significance.

Keywords: Balcony, Natural ventilation, Multi storey building.
Abstract: Incorporating airflow principles and techniques, and applying them in building designs can create comfortable indoor environments. Fa?ade characteristics, especially near the opening wall, can change airflow patterns and airspeed inside buildings. Balcony is an example of these features that can be used in front of openings to control the performance of indoor ventilation. Through literature review, this paper looks into the effeteness of the provision of balconies to induce natural ventilation in building. This paper reviews several studies on airflow patterns inside and outside buildings in single-sided and cross ventilation strategy as well as the impact of wind incidents, building height and balcony configuration on ventilation performance. The outcome of this study demonstrates that architects can incorporate balcony as a green design element to improve indoor natural ventilation.

Abstract: Background. The ethanolic and aqueous extract of C. aromaticus leaves and roots (100 mg kg-1 day-1 for 10 days) were evaluated for its wound healing activity in Monosodium Glumate induced diabetic mice using excision and dead space wound models. Excision wound model was performed on five different groups of mice to measure the progress of wound area for ten consecutive days. Dead space wound model was performed on four different groups of mice to estimate wet and dry granulation tissue as well as to examine the histological appearances of granulation tissue after ten days. Ethanolic extract treated wounds was found to show 76.6 % of wound area reduction when it is compared with controls that exhibited 55.9 % of wound area reduction. The ethanolic extract treated wound had epithelised faster compared to controls. The wet and dry granulation tissue weight has increased significantly in extract treated mice when it is compared with the controls. Extract treated mice exhibited good proliferation of collagen tissues with satisfactory angiogenesis. Coleus aromaticus promotes significant wound healing in induced diabetic mice and evaluation of this activity on human organism is highly suggested.

Abstract: Fungal strains are considered to be excellent sources for industrial polyphenol oxidase production. Polyphenol oxidase could be produced by endophytic fungus Trichothecium sp from podhusk of Theobroma cacao L. The aim of this research is to partial purify and characterize of the enzyme. The enzyme was produced by submerged fermentation using media with composition, i.e. 1% yeast extract, 25 ppm Cuso4.5H2O, 0.34 % gallic acid, 0.1% KH2PO4, 0.05 % MgSO4.7H2O. The steps of purification were done by 60-90 % (NH4)2SO4 precipitation, dialyzed, then partial purified by gel filtration chromatography using sephadex G-100, respectively. Polyacrylmide gel electrophoresis of the polyphenol oxidase showed 2 bands. Biochemical characteristics of the polyphenol oxidase are laccase and tyrosinase category. Opimum temperature and pH are 30 ? C and 7.0, respectively. The enzymes obeys Michealis-Menten kinetic with Km and Vmax values being 0.625 mM and 2083 U/mL, catechol as substrate.
