“…This black, dimorphic yeast is a dematiaceous fungus that is often found on dead wood, sewage sludge, and soil (Rayne and Boddy, 1988). Exophiala jeanselmei can utilize a variety of aromatic compounds as carbon and energy sources in pure culture, including urethanes, styrene, phenol, and other benzene-related compounds (Cox et al, 1993;Mid-delhoven, 1993;Owen et al, 1996). When used in biological reactors, E. jeanselmei has been shown to be tolerant of low moisture content and acidic environments (Cox et al, 1993).…”

“…Cadeias poliméricas contendo grupos funcionais hidrolisáveis podem ser clivadas enzimaticamente para produzir fragmentos de baixa massa molar que podem vir a ser repolimerizados. 58,59 Um poli(éster-uretano) (PEU) foi preparado pela ROP de oligô-meros cíclicos de éster-uretano, que foram preparados pela biodegradação de diuretanodiol (DUD) e diéster ácido dicarboxílico utilizando uma lipase de Candida antarctica (Novozym 435) e pela policondensação direta de DUD e diéster ácido dicarboxílico. Uma massa molar maior de PEU foi obtida pela ROP de éster-uretano cíclico (101.000 g/mol) quando comparado à policondensação direta de diéster ácido dicarboxílico com DUD (31.000 g/mol), ambas catalisadas por esta lipase, em condições de reação de 110 ºC.…”

“…Urethane compounds of low molecular mass can be hydrolyzed by microorganisms, and this hydrolysis is catalyzed by an esterase (Matsumura et al, 1985;Marty and Vouges, 1987;Pohlenz et al, 1992;Owens et al, 1996;Oshiro et al, 1997). But the investigation on bond degradation is not very extensive, and it is not clear yet if PU bonds are hydrolyzed directly or following breakdown into low-molecular-mass compounds (Filip, 1978;Jansen et al, 1991).…”
