Biodegradation of polyorganosiloxanes

Abstract

Biodegradation of various polyorganosiloxanes (about 30 substances) under the influence of several biotype bacteria strain (16 types) were studied. A special procedure of biodegradation and analytical methods of evaluation the degree of degradation were applied. It was found that nearly all polysiloxanes tested are biodegradable but the degree of degradation depends on their composition and structure, as well as on the type of bacteria strain chosen.

Decolorization and biodegradation of Reactive Blue 13 by Proteus mirabilis LAG

“…mirabilis is a Gram negative, facultative anaerobic bacterium. Along side, Pseudomonas aeruginosa, and Klebsiella pneumoniae, the organism has been reported to degrade organosilicone compounds [27]. While only few reports are available on the ability of the organism to decolorize azo dyes [28], no report exists to the best of our knowledge on its ability to mineralize such dyes.…”

Tailored design of Cu2O nanocube/silicone composites as efficient foul-release coatings

“…At the turn of 1970s, the possibility of their biodegradation has been proven. 48,49 Only few studies that focus on the biodegradation of various siloxanes have been reported. Nevertheless, the lack of studies did not affect the general assessment that polysiloxanes are a group of polymers that is difficult to biodegrade.…”

Efficient removal of siloxanes and volatile organic compounds from sewage biogas by an anoxic biotrickling filter supplemented with activated carbon

“…and Pseudomonas aeruginosa. Of them, P. aeruginosa is a facultative anaerobe that can proliferate with nitrate as a terminal electron acceptor and has been described as a siloxane-biodegrading species capable of producing biosurfactant molecules (Li et al, 2014;Rahman et al, 2002;Rościszewski et al, 1998).…”
