Research ArticleOpen accessCOMBINATION OF CONVENTIONAL AND IN-SILICO APPROACH FOR IDENTIFYING AN INDUSTRIALLY IMPORTANT ISOLATE OF AEROMONASThungri Ghoshal, Sourav Ghosh, Amrita Saha et al.Ammonia is required for various commercial applications while its production by standard process is immensely energy intense. Dairy industry on the other hand produces huge volume of effluent needing treatment before discharge. This study aims at developing an eco-friendly microbial approach for conversion of dairy industry effluent into ammonia under atmospheric pressure and 37°C temperature at laboratory scale. Thus the … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 26 Feb 2014 · 7,921 accessesView PDF Cite

Research ArticleOpen accessRapid Real Time PCR Based Detection of Cell Count in Case of Urinary Tract InfectionPoulomi Nandy, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriMicrobial identification and antimicrobial susceptibility testing methods currently used in clinical microbiology laboratories require at least two to three days because they rely on the growth and isolation of micro-organisms. This long, but necessary, delay has enormous consequences on prophylactic usage of antimicrobial drugs. This study was an attempt to reduce this detection time span. Taq Man Real Time PCR … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 22 Jun 2013 · 8,214 accessesView PDF Cite

Research ArticleOpen accessScreening of Bacteria for Lactic Acid Production from Whey WaterVethakanraj Helen Shiphrah, Sayanti Sahu, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriLactobacilli have the property of converting lactose and other sugars to lactic acid through fermentation. So whey water, the greenish translucent liquid rich in lactose, vitamins, proteins and mineral salts, obtained as a by-product after the precipitation of cheese can be used as a substrate for Lactobacilli for lactic acid production which otherwise is a serious environmental pollutant when disposed … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 9,340 accessesView PDF Cite

Research ArticleOpen accessAssay for Rapid Screening of Phytochemicals as Antimicrobial AgentsGhosh Saurav, Indranil Mukherjee, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriThe present study aims to develop a rapid method for antibiotic sensitivity detection and screening of natural products for antimicrobial activity. The dimension of WBC in blood film was found to get altered when seeded with bacteria and monitored under light microscope. The shrinkage was prevented in response to antibiotic treatment and validated using statistical analysis (two sample one tailed … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,303 accessesView PDF Cite

Research ArticleOpen accessMicrobial Consortia from Taptapani Hot Water Springs for Mining Effluent TreatmentPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriProblem statement: Soluble sulfate load in effluent is a crucial problem from mining industries. The study involved isolation of efficient Sulfate Reducing Bacterial (SRB) consortium from hot water spring for bioremediatrion of sulfate contaminated waste water. Approach: The enriched bacterial consortium was isolated in medium DSMZ 16695. The sulfate reduction efficiency was measured by turbidometric method. The Km and Rmax … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,461 accessesView PDF Cite

Research ArticleOpen accessCondoms-As Sources of Extracellular Enzyme Producing MicrobesMadhusmita Mishra, Poulomi Nandy, Sarvani Debsarma et al.Problem statement: Condoms are widely used birth control measures which are made of natural latex or synthetic materials like polyurethane or polyisoprene as matrix with lubricants added to make them ready to use commodities. Absence of sterilization method along with presence of lubricant like petroleum jelly (that are applied on the outer surface), prompted the investigators to look for microbes … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 8,985 accessesView PDF Cite

Research ArticleOpen accessBheri-A Unique Example of Biological Complex SystemIndranil Mukherjee, Pranami Bhaumik, Madhusmita Mishra et al.Problem statement: This study is a unique attempt to characterize Bheri (shallow flat bottom waste water fed fishery) as a complex biological system. Approach: The characterization was done both at the qualitative and the quantitative levels. The diverse microbial community and the associated emergent behaviors resulting in integrated resource recovery by the Bheris were analyzed under the lens of complexity … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,770 accessesView PDF Cite

Research ArticleOpen accessComparative Study of Soluble Sulfate Reduction by Bacterial Consortia from Varied Regions of IndiaPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriSoluble sulfate contamination in water is observed due to various industrial activities. Chemical means of reduction are available yet the biological approach is the preferred one. Problem statement: The problem addressed in this study was the isolation of efficient sulfate reducing bacterial consortia for bioremediation of soluble sulfate from mining effluent. Approach: The culture based method using the DSMZ specific … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,338 accessesView PDF Cite

Research ArticleOpen accessRadiation Induced DNA Double Strand Break Studies of a Metal Sensitive Novel Bacterial Isolate from East Calcutta WetlandSanhita Chowdhury, Anindita Chakraborty, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriProblem statement: This study was an attempt to isolate anaerobic microbes with potential for DNA double strand break repair using methanogen specific medium (DSMZ 120) from East Calcutta Wetland in India. It also intended to verify the specificity of the medium for isolation of the desired family of microbe. Approach: Culture based technique was used to obtain the pure isolate … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 7,123 accessesView PDF Cite

Research ArticleOpen accessCharacterization and Wash Performance Analysis of Microbial Extracellular Enzymes from East Calcutta Wetland in IndiaRamesh Malathu, Sanhita Chowdhury, Madhusmita Mishra et al.Extracellular protease from a novel bacterial isolate showing maximum similarity of 98.22% with Microbacterium luteolum was obtained from East Calcutta Wetland, India. It showed compatibility with commercial detergents. The enzyme retains more than 60% of its activity between 6.0 to 10.5 pH. The maximum activity is at pH 7.5 with 71% activity at pH 10.0 and 10.5. The protease retained … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 8,727 accessesView PDF Cite
