GCMS and FTIR spectral analysis of aqueous methylparathion biotransformation by the microbial mpd strains of Pseudomonas aeruginosa and Fusariumspp was written by Krishnaswamy, Usharani. And the article was included in Archives of Microbiology in 2021.Formula: C6H12O2 This article mentions the following:
This study aimed to find out the effective biotreatment processes of aqueous methyl parathion in stipulations of its biotransformation by potential indigenous mpd strains of Pseudomonas aeruginosa and Fusariumspp. Microbial biotransformation study of methyl parathion in contaminated synthetic wastewater at optimum conditions by P. aeruginosa mpd-5 (at temperature 33 °C, pH 7, under the aerobic condition with inoculum d. of 108cells/mL) and by Fusarium spp mpd-1 (at temperature 30 °C, pH 7, under the aerobic condition with inoculum d. of 25 mgL-1 dry biomass) was carried out. The major biodegradation compounds formed during the biotreatment process were analyzed by spectral studies using GCMS and FTIR. GCMS anal. of bacterial transformed compounds was p-nitrophenol, dimethylaminophenol, and glycyl-L-proline of 2-(3-methylpiperidino-4-5, 6-benzothiazin-4-one) and 2, 5-piperazinodione 3, 6-bis (2-methylpropyl). And the fungal transformed compounds were observed to be p-nitrophenol, phenol,2,4-Bis(1,1-Dimethylethyl), beta-L-arabinopyranoside-Me, Cyclobutanethiol, 3-2(4)-thiophenone, dihydro-5-(1-methylethyl), Benzene,1,3-bis(1,1-di-Me ethyl), Butanoic acid, 2-Me Me ester, and L-(+)-Ascorbic acid. The FTIR spectra of the mol. and the products of methyl parathion are observed to be changed in structures. It can be concluded from the aforementioned results and discussions that P. aeruginosa mpd-5 and Fusarium spp mpd-1 can be used in the biotreatment of pesticide wastewater having the high methyl parathion concentration and is possible by the indigenous microbial strains; they utilize as phosphate and carbon source of energy. Hence the strains can be used as a whole microbial cell, or its bioactive metabolites can be applied for the biotreatment of pesticide wastewater and potentially degrade methylparathion. In the experiment, the researchers used many compounds, for example, Methyl2-methylbutyrate (cas: 868-57-5Formula: C6H12O2).
Methyl2-methylbutyrate (cas: 868-57-5) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Formula: C6H12O2
