A rapid, cost effective method of metagenomic DNA extraction from soil is a useful tool for environmental microbiology. The present work describes an improved method of DNA extraction namely "powdered glass method" from diverse soils. The method involves the use of sterile glass powder for cell lysis followed by addition of 1% powdered activated charcoal(More)
Arthrospira species, under the name ‘Spirulina’, are used as food supplement for its protein, vitamins, and minerals which have several health benefits. Cyanobacterial toxins including microcystins can possibly contaminate these dietary supplements causing hepatotoxicity, tumour formation, and other disorders. The safe use of dietary supplements(More)
The performance of the quantitative polymerase chain reaction (qPCR) assay in the analysis of gene expression belonging to multigene families in tissues rich in secondary metabolites is technically complicated. Here, we present the qPCR analysis of PMT2 gene, a predominant member of a multigene family from tobacco, expressed in the root tissues and is(More)
New Delhi metallo-β-lactamase-1 gene (bla NDM-1 ) codes for New Delhi metallo-beta-lactamase-1 (NDM-1) enzyme that cleaves the amide bond of β-lactam ring, and provides resistance against major classes of β-lactam antibiotics. Dissemination of the plasmid borne bla NDM-1 through horizontal gene transfer is a potential threat to the society. In this study, a(More)
