“…Brevibacillus borstelensis as well as S. albogriseolus in our study were found to reduce sulfosulfuron into aminopyrimidine and a rearranged amine due to the cleavage or opening of the sulfonylurea bridge of the sulfosulfuron as also discussed elsewhere (Sondhia and Singhai 2008; Saha et al 2003). Similarly, consortium containing B. borstelensis and S. albogriseolus grown together reduced sulfosulfuron into aminopyrimidine and a rearranged amine which may have resulted because of the cleavage or opening of the sulfonylurea bridge of the sulfosulfuron (Saha et al 2003; Saha and Kulshrestha 2002).…”

“…4) and is degradation products have been identified as 1-(2-ethylsulfonylimidazo[1,2-a]pyridine)-3-(4,6-dimethoxypyramidin-2-yl), 1-(2-ethylsulfonylimidazo [1,2-a]pyridine)-3-sulfonamide and 4,6-dimethoxy-2-aminopyramidine (Sondhia and Singhai 2008). Breakdown of pesticides could occur by plants, animals, soil, water and UV radiations, but degradation by microbes, especially fungi and bacteria, is foremostly important (Arya and Sharma 2014a, b, 2015, 2016).…”

“…chlorosulfuron, nicosulfuron, flazosulfuron, triasulfuron and sulfosulfuron was studied and their degradation followed first order kinetics and none of the pesticides were detected after 120 min of illumination except chlorosulfuron (Fenoll et al 2012). Sondhia and Singhai (2008) have shown in their study, the cleavage of the sulfonylurea bridge to form 1-(2-ethylsulfonylimidazo [1, 2-a] pyridine)-3-sulfonamide and 4, 6-dimethoxy-2-aminopyramidine. Ramesh et al (2007) through LCMS/MS analysis on water and fish samples, explored the presence of metabolites, ethyl sulfone, aminopyrimidine, desmethyl sulfosulfuron, sulphonamide, guanidine and a rearranged amine.…”

Use of herbicides, in particular sulfosulfuron, at more than recommended doses has raised major concerns about the health hazards for animals and humans. In the present study, isolation of sulfosulfuron-degrading Brevibacillus borstelensis and Streptomyces albogriseolus from the field soils in the northwestern region of India was carried out where the use of sulfosulfuron is predominant, and further assessed for their potential to degrade sulfosulfuron individually and together in a consortium form under lab conditions. Concentration of sulfosulfuron was reduced from 10 to 7.72 µg/ml in 12 h to 5.13 µg/ml in 20 h by B. borstelensis and the metabolites detected by LCMS–MS were aminopyrimidine and a rearranged amine in 12 and 20 h of growth. Similarly, S. albogriseolus reduced the concentration of sulfosulfuron from 10 to 6.74 µg/ml in 12 h to 6.62 µg/ml in 20 h with aminopyrimidine and a rearranged amine as metabolites. B. borstelensis and S. albogriseolus together also reduced the concentration of sulfosulfuron from 10 µg/ml in initial hour to 8.34 µg/ml in 12 h to 6.66 µg/ml in 20 h. Hence, B. borstelensis and S. albogriseolus provide a safer, inexpensive and effective way to bio-remediate the harmful and toxic sulfosulfuron from the environment if further explored at a larger field scale in near future.

“…Excessive herbicide usage has caused serious ecological and environmental problems, such as resistance and shifts in weed population . The presence of herbicides may adversely affect human and animal health due to bioaccumulation of residues in crop produce . The results of the audit on pesticide residues in cereal grains throughout Poland in 2013 shows that 34% of samples of cereal grains contained such residues but below the maximum allowed residue limit, 3% contained residues over the maximum allowed limit, and 1% of the samples contained illegal substances in the samples analyzed .…”

BACKGROUND: Higher alcohols and esters have a negative impact on ethanol quality; therefore, to analyze the influence of mycotoxins and pesticides on higher alcohols and esters formation during ethanol production from contaminated cereal grains is of outstanding importance. RESULTS:In this study, the yield of ethanol and the composition of volatile by-products (acetaldehyde, methyl acetate, ethyl acetate, methanol, propanol, isobutanol, amyl and isoamyl alcohols) after fermentation of wheat grains artificially contaminated with Fusarium sporotrichioides and pesticides (triasulfuron and sulfosulfuron) were analyzed. Wheat grains contamination with triasulfuron significantly reduced ethanol yield and increased isobutanol and ethyl acetate content. Moreover, wheat grains infection with F. sporotrichioides significantly increased methyl acetate, ethyl acetate, isobutanol, and amyl and isoamyl alcohols content. Significant differences between pesticides and wheat variety on volatile compounds formation in ethanol has been estimated. CONCLUSION:The results showed that grains contaminated with F. sporotrichioides and pesticides significantly influenced the process of alcoholic fermentation that leads to variation of by-products in ethanol, including higher alcohols, esters, and aldehydes.

“…Oxyfluorfen was also shown to drift from application sites to nearby areas and has the potential to adversely affect terrestrial plants and aquatic ecological systems at all levels (US EPA 1992). At harvest detection of low residues, levels in soil may be due to adsorption of oxyfluorfen in soil due to high organic matter content (Shelton and Parkin 1991;Wauchope et al 1992;WSSA 1994;Sondhia 2005Sondhia , 2008bSondhia, Singhai, and Singh 2007;Sondhia and Singhai 2008). In addition to organic matter, the clay content can also play an important role in degradation rate of pesticides (Sondhia 2008a).…”

Oxyfluorfen is a post-emergence herbicide used for control of annual and perennial broad-leaf weeds and sedges in rice. There is increasing concern about persistence of pesticide residues in soils, agricultural products and subsequent contamination of ground water through runoff, leaching and drift. Thus, persistence of oxyfluorfen was evaluated under field conditions in a rice cropping system. Oxyfluorfen was sprayed at 240 and 500 g ai ha À1 application rates to the rice crop as post-emergence herbicide. Paddy grains, straw and soil samples were collected at harvest and analyzed for oxyfluorfen residues by HPLC. Straw samples contained 0.01 and 0.03 mg g À1 oxyfluorfen residues at 240 and 500 g ha À1 concentrations, respectively. In the soil, 0.028 and 0.03 mg g À1 of oxyfluorfen residues were detected when applied at 240 and 500 g ai ha À1 , respectively. However, in rice grains, 0.018 and 0.106 mg g À1 of oxyfluorfen residues were found in 240 and 500 g ai ha À1 treated plots. In light of the potential adverse effects of oxyfluorfen, it is important to determine herbicide levels in these crops.
