New aspects on atrazine biodegradation

Abstract

ABSTRACT

Identification of an Indigenous Atrazine Herbicide Tolerant Microbial Consortium in Beans (Phaseolus vulgaris L.) as a Potential Soil Bioremediator

“…Assays relating minimum inhibitory concentration and type of microorganisms yield good results in terms of the number of species and tolerance to the herbicide. This last is compared to other studies [6,20,34,35]. Bacteria identified are inhibited to a greater extent from 5,000 mg L -1 of atrazine, except Rhizobium sp.…”

“…Due to its organizational structure, atrazine can experience natural or induced degradation processes such as: (i) hydrolysing and (ii) oxidative -hydrolytic, two very well studied degradation mechanisms. Reports [4][5][6][7][8] showed that atrazine degradation can be achieved by isolated microbial consortia species in combination with other bioremediation techniques.…”

Occurrence of Atrazine Biodegrading Bacterium "Ochrobactrum oryzae" In Agricultural Wastewater

“…Some bacterial strains metabolized atrazine to diethylatrazine or hydroxyatrazine, while others mineralized it by cleavage the ring. The catabolic pathway, enzymes and corresponding genes involved in atrazine degradation, were characterized in some bacterial strains (Mandelbaum et al, 1995;Sene et al, 2010 andWang et al, 2011).…”

s-triazine degrading bacterial isolate Arthrobacter sp. AK-YN10, a candidate for bioaugmentation of atrazine contaminated soil

“…It is an endocrine disruptor reported to cause sex reversal in frogs (Hayes et al 2002(Hayes et al , 2010. Furthermore, striazine compounds and their metabolites have been reported to induce mammary gland tumors in Sprague-Dawley female rats (Sene et al 2010). Hence, removal of these toxic compounds from the environment is important for the ecological balance.…”
