Microorganisms and Fermentation of Traditional Foods

Abstract: Presentation de l'editeur : The first volume in a series covering the latest information in microbiology, biotechnology, and food safety aspects, this book is divided into two parts. Part I focuses on fermentation of traditional foods and beverages, such as cereal and milk products from the Orient, Africa, Latin America, and other areas. Part two addresses fermentation biology, discussing specific topics including microbiology and biotechnology of wine and beer, lactic fermented fruits and vegetables, coffee and cocoa fermentation, probiotics, bio-valorization of food wastes, and solid state fermentation in food processing industries.

Biosynthesis of tannin acyl hydrolase from tannin-rich forest residue under different fermentation conditions

Abstract: Caesalpinia digyna, a tannin-rich forest residue, was used as substrate for production of tannase and gallic acid. Media engineering was carried out under solid-state fermentation, submerged fermentation and modified solid state fermentation conditions for optimum synthesis of tannase and gallic acid (based on 58% tannin content in the raw material). Tannase vis-a-vis gallic acid recovery under modified solid-state fermentation condition was maximum. Conversions of tannin to gallic acid under solid-state fermentation, submerged fermentation and modified solid-state fermentation conditions were 30.5%, 27.5% and 90.9%, respectively.

Optimization of Lignin Peroxidase, Manganese Peroxidase, and Lac Production from Ganoderma lucidum Under Solid State Fermentation of Pineapple Leaf

Abstract: This study was undertaken to isolate ligninase-producing white-rot fungi for use in the extraction of fibre from pineapple leaf agriwaste. Fifteen fungal strains were isolated from dead tree trunks and leaf litter. Ligninolytic enzymes (lignin peroxidase (LiP), manganese peroxidase (MnP), and laccase (Lac)), were produced by solid-state fermentation (SSF) using pineapple leaves as the substrate. Of the isolated strains, the one showing maximum production of ligninolytic enzymes was identified to be Ganoderma lucidum by 18S ribotyping. Single parameter optimization and response surface methodology of different process variables were carried out for enzyme production. Incubation period, agitation, and Tween-80 were identified to be the most significant variables through Plackett-Burman design. These variables were further optimized by Box-Behnken design. The overall maximum yield of ligninolytic enzymes was achieved by experimental analysis under these optimal conditions. Quantitative lignin analysis of pineapple leaves by Klason lignin method showed significant degradation of lignin by Ganoderma lucidum under SSF.

Growth and laccase production by Pleurotus ostreatus in submerged and solid-state fermentation.

Abstract: Pleurotus ostreatus showed atypical laccase production in submerged vs. solid-state fermentation. Cultures grown in submerged fermentation produced laccase at 13,000 U l−1, with a biomass production of 5.6 g l−1 and four laccase isoforms. However, cultures grown in solid-state fermentation had a much lower laccase activity of 2,430 U l−1, biomass production of 4.5 g l−1, and three laccase isoforms. These results show that P. ostreatus performs much better in submerged fermentation than in solid-state fermentation. This is the first report that shows such atypical behavior in the production of extracellular laccases by fungi.
