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...

Mota, Monalize Salete; Gomes, Cesar Bauer; Souza Júnior, Ismail Teodoro; Moura, Andréa Bittencourt.
Braz. j. microbiol; 48 (1), 2017
Abstract This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial com...
