Electron. j. biotechnol; 40 (), 2019
Background: Plastic waste is a serious problem because it is difficult to degrade, thereby leading to global environment problems. Poly(lactic acid) (PLA) is a biodegradable aliphatic polyester derived from renewable resources, and it can be degraded by various enzymes produced by microorganisms. This st...

Poly(DL-lactide)-degrading enzyme production by immobilized Actinomadura keratinilytica strain T16-1 in a 5-L fermenter under various fermentation processes

Panyachanakul, Titiporn; Kitpreechavanich, Vichien; Tokuyama, Shinji; Krajangsang, Sukhumaporn.
Electron. j. biotechnol; 30 (), 2017
Background: Poly(DL-lactic acid), or PDLLA, is a biodegradable polymer that can be hydrolyzed by various types of enzymes. The protease produced by Actinomadura keratinilytica strain T16-1 was previously reported to have PDLLA depolymerase activity. However, few studies have reported on PDLLA-degrading e...

A novel pH-stable, endoglucanase (JqCel5A) isolated from a salt-lake microorganism, Jonesia quinghaiensis

Lin, Ling; Liu, Xiaozhou; Zhou, Yating; Guan, Linyan; Jiajia, He; Huang, Weiqian.
Electron. j. biotechnol; 19 (6), 2016
Background: Endoglucanase, one of three type cellulases, can randomly cleave internal p-1,4-linkages in cellulose polymers. Thus, it could be applied in agricultural and industrial processes. Results: A novel endoglucanase gene (JqCel5A) was cloned from Jonesia quinghaiensis and functionally expressed in...
