The Arthrobacter sp. strain AK-YN10 is an s-triazine pesticide degrading bacterium isolated from a sugarcane field in Central India with history of repeated atrazine use. AK-YN10 was shown to degrade 99 % of atrazine in 30 h from media supplemented with 1000 mg L−1 of the herbicide. Draft genome sequencing revealed similarity to pAO1, TC1, and TC2 catabolic(More)
Molecular tools in microbial community analysis give access to information on catabolic potential and diversity of microbes. Applied in bioremediation, they could provide a new dimension to improve pollution control. This concept has been demonstrated in the study using atrazine as model pollutant. Bioremediation of the herbicide, atrazine, was analyzed in(More)
Accumulation of pesticides in the environment causes serious issues of contamination and toxicity. Bioremediation is an ecologically sound method to manage soil pollution, but the bottleneck here, is the successful scale-up of lab-scale experiments to field applications. This study demonstrates pilot-scale bioremediation in tropical soil using atrazine as(More)
We report a draft genome sequence of Alcaligenes sp. strain HPC1271, which demonstrates antimicrobial activity against multidrug-resistant bacteria. Antibiotic production by Alcaligenes has not been frequently reported, and hence, the availability of the genome sequence should enable us to explore new antibiotic-producing gene clusters. A lcaligenes sp.(More)
Alcaligenes sp. HPC 1271 demonstrated antibacterial activity against multidrug resistant bacteria, Enterobacter sp., resistant to sulfamethoxazole, ampicillin, azithromycin, and tetracycline, as well as against Serratia sp. GMX1, resistant to the same antibiotics with the addition of netilmicin. The cell-free culture supernatant was analyzed for possible(More)
OBJECTIVE Chronic exposure to atrazine and other pesticides is reported to cause metabolic disorders, yet information on effects of atrazine on expression of genes relevant to mitochondrial function is largely missing. In the present study, therefore, we investigated the expression of a battery of nuclear- and mitochondrial-encoded genes involved in(More)
We report the draft genome sequences of two tropical bacterial isolates capable of degrading the herbicide atrazine. Alcaligenes sp. strain EGD-AK7 and Arthrobacter sp. strain AK-YN10 were isolated from Indian agricultural soil in which sugarcane is grown, with a reported history of atrazine use. EGD-AK7 has the atzABCDEF genes and AK-YN10 has the trzN and(More)
Minimal traumatic brain injury (MTBI) often transforms into chronic neuropsychiatric conditions including anxiety, the underlying mechanisms of which are largely unknown. In the present study, we employed the closed-head injury paradigm to induce MTBI in rats and examined whether DNA methylation can explain long-term changes in the expression of the(More)
Strategies for bioremediation of atrazine, a pesticide commonly polluting groundwater in low concentrations, were studied in two boreal nonagricultural soils. Atrazine was not mineralized in soil without bioremediation treatments. In biostimulation treatment with molasses, up to 52 % of atrazine was mineralized at 10 °C, even though the degradation gene(More)
BACKGROUND Stress-induced chronic neuropsychiatric conditions such as anxiety are often co-morbid with gastrointestinal malfunctions. While we find enduring anxiety-like symptoms following minimal traumatic brain injury (MTBI) in rats, gastrointestinal consequences of MTBI remain elusive. METHODS In this study, we examined the effects of MTBI on a major(More)
