Xenobiotics enhance laccase activity in alkali-tolerant γ-proteobacterium JB

摘要

Various genotoxic textile dyes, xenobiotics, substrates (10 μM) and agrochemicals (100 μg/ml) were tested for enhancement of alkalophilic laccase activity inγ-proteobacterium JB. Neutral Red, Indigo Carmine, Naphthol Base Bordears and Sulphast Ruby dyes increased the activity by 3.7, 2.7, 2.6 and 2.3 fold respectively. Xenobiotics/substrates like p-toluidine, 8-hydroxyquinoline and anthracine increased it by 3.4, 2.8 and 2.3 fold respectively. Atrazine and trycyclozole pesticides enhanced the activityby 1.95 and 1.5 fold respectively.
