Some intermediate bio-transformants during biodegradation of high molecular weight phenanthrene and fluoranthene by cyanobacterial species – Aulosira fertilissima ghose was written by Nirmal Kumar, J. I.;Barot, Megha;Khan, Shamiyan R.. And the article was included in International Journal of Applied Sciences and Biotechnology in 2013.Quality Control of Dimethyl decanedioate This article mentions the following:
The PAHs compounds are known to be carcinogenic, teratogenic, mutagenic and toxic to all living organism. Handful of literature is available on biodegradation of these compounds by bacteria and fungi, however, scanty work is done by using microalgae on biodegradation of these two PAHs. In this investigation, the efficiency of Aulosira fertilissima Ghose to remove fluoranthene (0.001gm.ml-1), phenanthrene (0.001gm.ml-1) and a mixture of both (each at concentration of 0.0005gm.ml-1) were evaluated for intermediate bio-transformants during biodegradation by using GCMS. The result showed that the efficiency of Aulosira fertilissima for removal and biodegradation of phenanthrene was higher than fluoranthene, indicate fluoranthene was more stable and recalcitrant. PAHs uptake after 7-days of treatment was 80% and 66% of these phenanthrene and fluoranthene ,resp. by the cyanobacteria .The synergetic effect of fluoranthene on phenanthrene was observed, presence of fluoranthene stimulate the degradation of phenanthrene due to which phenanthrene produce more bio-transformants . Some intermediates were observed like Me linoleate, 4-(2,2- dimethyl-6-methylenecyclohexylidene)-3-methyl-,(Z)- etc. for phenanthrene biodegradation process while 2,3-dihydrofluoranthene, (1R,5R)-2-isopropyl-5-methylcyclohexanol, for fluoranthene degradation Moreover, 3-isopropylidene-2,2-dimethyl-6-phenyl-1,4-oxathiane, 7- phenyltridecane, diphenylacetylene, for mixture of two PAHs applied. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Quality Control of Dimethyl decanedioate).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Quality Control of Dimethyl decanedioate
