Mixed-species Pseudomonas biofilms: a novel and sustainable strategy for malachite green dye decolorization and detoxification.

This study investigated the application of mixed biofilms formed by two Pseudomonas strains (NAA22 and NAA23) for bio-decolorization of malachite green (MG) dye. The isolated strains displayed biofilm formation and MG decolorization capabilities. Mixed biofilms exhibited significantly greater biofilm formation and MG decolorization (94.

Heavy metal status and oxidative stress in diesel engine tuning workers of central Indian population.

Objective: To assess the oxidative stress induced due to heavy metal exposure. Exposed populations are selected from an engine tuning station and control from the same area with no occupational exposure.

Method: Standard methods were followed for enzymatic assay, and heavy metals in blood and urine were analyzed by using inductively coupled plasma-optical emission spectrophotometer after microwave digestion.
