Soil microbial diversity is an important index of agricultural productivity by enhancing soil quality. Present study employed the combination of several methodologies to examine genetic relationships among specific groups of bacteria and to characterize strains at the species level using molecular biotyping techniques. The present study is based upon 16SrDNA analysis for characterisation of bac...

Escherichia coli and other Proteobacteria are augmented and several other bacteria are diminished in Crohn’s (CD) disease patients’ intestine. This imbalance in bacterial species composition—termed dysbiosis—seems to be determinant of CD manifestation. Since a great part of intestinal bacteria are not cultivable, detection of CD dysbiosis is accomplished by molecular tools, involving sequences ...

The small scale industries located at Mira Road, Mumbai, are engaged in various processes/operations which generate the wastes. The waste generated are collected and disposed of at the dumping ground near the industrial estate. In the present study, the physico-chemical and microbial status of the contaminated sites has been carried out. The heavy metal with special reference to copper was expo...

introduction and aims: until today human stomach is the only recognized habitat of h. pylori . however, recruitment of dna-based methods has made possible the detection of h. pylori in water and oral cavity, thus suggesting faecal-oral and oral-oral routes for transmission of h. pylori , respectively. in this study yeast has been proposed as a common vector for transmission of h. pylori . thus ...

Phytoextraction has been reported as an economically and ecologically sound alternative for the remediation of metal-contaminated soils. Willow is a metal phytoextractor of interest because it allows to combine a gradual contaminant removal with production of biomass that can be valorized in different ways. In this work two willow clones growing on a metal-contaminated site were selected: 'Belg...

ریزوباکتری های ارتقا دهنده رشد گیاه (pgpr) گروهی از باکتری ها هستند که در حاصلخیزی خاک نقش مهمی دارند. باسیلوس ها دسته ای از pgprها هستند که یکی از فعالیت های آن ها تجزیه فیتات خاک و تبدیل آن ها به اشکال فسفر قابل جذب برای گیاه است. فیتاز آنزیمی است که وظیفه تجزیه فیتات (فسفر آلی خاک) را برعهده دارد. در این پژوهش سه باکتری خاکزی با توجه به فنوتیپ کلونی از خاک جداسازی و خالص سازی شد. با تکثیر و ...

Bacterial contamination in dental unit waterlines (DUWLs) was evaluated by molecular techniques in addition to the conventional culture method. Water samples (n=8) from DUWLs were investigated for heterotrophic bacteria by culture method using R2A agar. The selected bacterial antibiotic-resistance genes and Legionella species-specific 16SrDNA were identified by PCR. The profiles of bacterial co...
