The surge of Antibiotic Resistant Bacteria (ARB) in the environment is poised to be the next health threat. World Health Organisation's (WHO's) Global Antimicrobial Surveillance System (GLASS) report indicates that developing countries may be at a greater risk. Among various factors, the major driver here could be untreated wastewater and poor sanitation.

Analysis of the physicochemical properties and functions of indigenous microbes of the contaminated sites are essential in deciding the strategy for bioremediation. This study analyses both parameters at two geographically distant sites, with different crude oil sources, and compares the metabolic capability of soil bacteria with reference to different contamination sources and the age of the contaminated site.

Two novel triterpenoid glycosides have been isolated from butanolic seeds extract of two varieties of Lathyrus plants, i.e. Lathyrus ratan and Lathyrus aphaca.
View Article and Find Full Text PDFA novel oleanen type triterpenoid glycoside has been isolated from butanolic seed extracts of Cassia angustifolia. Its structure was elucidated as 3-O-{beta-D-glucuronopyranosyl-(1 --> 4)-[beta-D-galactopyranosyl-(1 --> 2)]-beta-D-xylopyranosyl-(1 --> 3)-beta-D-glucopyranosyl}-2, 16alpha-dihydroxy-4, 20-hydroxy methyl olean-12-ene-28-oic acid on the basis of spectral evidence (i.e.
