Augmented complete mineralization of glyphosate in wastewater via microbial degradation post CWAO over supported Fe-CNF

Effects of Free or Immobilized Bacterium Stenotrophomonas acidaminiphila Y4B on Glyphosate Degradation Performance and Indigenous Microbial Community Structure

“…Some degraders are capable of degrading 90% of the present glyphosate within 5 days under the optimal capacity, such as Ochrobactrum sp. GDOS (504 mg L –1 within 2.5 days), Ochrobactrum intermedium Sq20 (500 mg L –1 within 4 days), Comamonas odontotermitis P2 (1.5 g L –1 within 5 days), and Bacillus cereus CB4 (6 g L –1 within 5 days). − Recently, Gupta et al used a bacterium, Providencia vermicola, combined with an advanced oxidation process (AOP), to achieve complete degradation of glyphosate (100 mg L –1 ) within 4 h.…”

Decomposition and mineralization of glyphosate herbicide in water by radical and non-radical pathways through peroxymonosulfate activation using Co3O4/g-C3N4: a comprehensive study

“…In strongly alkaline environments ( e.g. pH 11), the main existing form of PMS is SO 5 ; 2 thus, the reactions can take place to form reactive oxygen species ( e.g. , 1 O 2 , O 2 ˙ − , and HO˙) (reactions (7) and (14)–(18)).…”

“…92,97 The wet oxidation method has the advantage of treating Gly at high content (e.g., 100 mg L −1 ) but its disadvantage is that the reaction conditions occur at high temperature and high pressure with relatively low decomposition efficiency. 2,94 The comparison results show that our study has some advantages such as low doses of catalyst (50 mg L −1 ) to activate PMS (200 mg L −1 ), which can decompose Gly at a very high efficiency of 87.18% after a short reaction time of 30 s. The decomposition of Gly is mainly caused by oxygen species of 1 O 2 and O 2 ˙−. Meanwhile, the activation of PMS by heterogeneous catalysis using Co 3 O 4 /g-C 3 N 4 does not require an energy supply (e.g.…”

“…5 Therefore, several methods for controlling Gly residues in an aqueous medium have been reported. The methods for removing Gly from pollution sources are mainly adsorption 6,7 and oxidation processes, such as wet air oxidation conditions, 8 catalytic wet air oxidation under atmospheric conditions, 2,9 catalytic activation, 10,11 and photocatalysis. 12 Among them, advanced oxidation processes (AOPs) are more promising than the other methods since AOPs can mineralize toxic and hard-biodegradable pollutants or partially decompose them into simple and less toxic compounds.…”

“…However, Gly concentrations range from 50 to 76 mg L −1 as a result of improper rinsing of the herbicide container. 2 This causes severe effects on many organisms, causing genotoxicity, cytotoxicity, nuclear aberrations, hormonal disruption, chromosomal aberrations, and DNA damage. Its toxicity occurs in unicellular and multicellular organisms and has also been observed in many vertebrates, including humans.…”
