对各种微生物降解聚(丁二酸四亚甲酯)-己二酸四亚甲酯(PBSA)的能力进行了筛选。从土壤样品中新分离到的菌株BS-3被选为最佳菌株。根据分类学研究，该菌株初步归属于Acidovorax属，最可能属于A.delafieldii种。菌株BS-3能降解固体PBSA和乳化PBSA，也能降解乳化聚丁二酸丁二醇酯。在降解过程中，在发酵液中观察到脂肪酶活性。与典型的脂肪酶底物三丁酸甘油酯或三油酸甘油酯相比，PBSA对该脂肪酶活性的诱导作用更强。这些观察结果有力地表明，该脂肪酶参与了菌株BS-3对PBSA的生物降解。(C)2000年欧洲微生物学会联合会。爱思唯尔科学公司出版，版权所有。
Various microorganisms were screened for their ability to degrade poly(tetramethylene succinate)-co-(tetramethylene adipate) (PBSA). Strain BS-3, which was newly isolated from a soil sample, was selected as the best strain. From taxonomical studies, the strain was tentatively ascribed to belong to the genus Acidovorax, most probably to the species A. delafieldii. Strain BS-3 could degrade both solid and emulsified PBSA, and also emulsified poly(tetramethylene succinate). During the degradation, a lipase activity was observed in the culture broth. This lipase activity was induced more strongly by PBSA than by tributyrin or triolein which are typical substrates of lipase. These observations strongly suggest that this lipase was involved in the PBSA biodegradation in strain BS-3. (C) 2000 Federation of European Microbiological Societies.
