چکیده

Blue mold is one of the most serious postharvest diseases in apples caused by Penicillium expansum. The purpose this study to determine effect ε-poly-L-lysine (ε-PL) on pathogenicity P. expansum and explore potential mechanism from perspective organic acid. investigates ε-PL treatment growth acid production vitro vivo. When concentration was 50 mg/L, inhibited decrease pH value delayed medium. For example, third day culture, reduced medium 6.1 4.15, at 34.4%. reached 1000 or 2000 infection fruits effectively inhibited. During expansum, gluconic main factors leading falling local environment. After treatment, accumulation decreased, activity glucose oxidase suppressed, then decline environmental slowed down. In addition, after activities cell-wall-degrading enzymes, such as cellulase (CL) polygalacturonase (PG), different areas expansum–apple interaction were also affected change. results show that affecting slowing fruit tissues, so affect This first time interfering with acids clarified.

Cloning of ε-poly-L-lysine (ε-PL) synthetase gene from a newly isolated ε-PL-producing Streptomyces albulus NK660 and its heterologous expression in Streptomyces lividans

ε-Poly-L-lysine (ε-PL), showing a wide range of antimicrobial activity, is now industrially produced as a food additive by a fermentation process. A new strain capable of producing ε-PL was isolated from a soil sample collected from Gutian, Fujian Province, China. Based on its morphological and biochemical features and phylogenetic similarity with 16S rRNA gene, the strain was identified as Str...

Enhancement of ε-poly-l-lysine (ε-PL) production by a novel producer Bacillus cereus using metabolic precursors and glucose feeding

Epsilon poly-L-lysine (ε-PL) is a homo-biopolymer with approximately 25-30 L-lysine residues. It is a promising natural biopolymer widely used in food and pharmaceutical industry. The present work reports enhanced production of ε-PL with a novel producer Bacillus cereus using amino acids and TCA cycle intermediates in the fermentation medium. Among the various amino acids and TCA cycle intermed...
