This study presents the isolation and molecular characterization of bacterial strains utilizing 1, 7, 7-Trimethylbicyclo (2.2.1) heptane-2-one (camphor) as a sole source of carbon, isolated from the biomass sludge sample collected from an effluent treatment plant of Mathura Refinery Limited (MRL), India. Initial screening was carried out where the 16S rDNA PCR was performed using reported eubac...
room temperature. In plain broth there was surface growth, indicated by a whitish ring in contact with the glass, and a viscid sediment, partially disintegrating on shaking. In gelatine stab, growth occurred without liquefaction. Fermentation and biochemical reactions were as follows : No change in glucose, maltose, lactose, sucrose, mannitol or salicin. M.R. and V.P. reactions negative; no red...
The kinetics of denitrification and the causes of nitrite and nitrous oxide accumulation were examined in resting cell suspensions of three denitrifiers. An Alcaligenes species and a Pseudomonas fluorescens isolate characteristically accumulated nitrite when reducing nitrate; a Flavobacterium isolate did not. Nitrate did not inhibit nitrite reduction in cultures grown with tungstate to prevent ...
The enzyme 2,4'-dihydroxyacetophenone dioxygenase (DAD) catalyses the conversion of 2,4'-dihydroxyacetophenone to 4-hydroxybenzoic acid and formic acid with the incorporation of molecular oxygen. Whilst the vast majority of dioxygenases cleave within the aromatic ring of the substrate, DAD is very unusual in that it is involved in C-C bond cleavage in a substituent of the aromatic ring. There i...
