摘要

研究人员评估了储存在国家非致病微生物收集(CNMN)中的细菌、放线菌和微菌的生长和降解LDPE的能力。检出假单胞菌属、芽孢杆菌属、链霉菌属、红球菌属细菌15株,青霉属、曲霉属微菌15株。在所研究的菌株中,放线菌对LDPE的降解效果优于杆菌和假单胞菌,青霉菌对LDPE的降解效果优于曲霉菌。

Screening of low density polyethylene degrading microorganisms
Bacteria, actinobacteria, and micromycetes stored in the National Collection of NonPathogenic Microorganisms (CNMN) were assessed for the capacity to grow and degrade LDPE. There were tested 15 strains of bacteria from genera Pseudomonas, Bacillus, Streptomyces, and Rhodococcus, and 15 strains of micromycetes from genera Penicillium and Aspergillus. Among the studied bacterial strains, actinobacteria were more effective in LDPE degradation than bacilli and Pseudomonas spp. The members of genus Penicillium, in comparing with Aspergillus spp., degraded LDPE more actively.
