Catabolic pathways generate energy by utilizing: carbohydrates, proteins and fats in metabolic cycles. 564 METABOLIC PATHWAYS j Production of Secondary Metabolites of Bacteria Encyclopedia of Food Microbiology, Second Edition, 2014, 561-569 Author's personal copy. , 2001), various primary and secondary metabolites, bioprocess such as bioleaching, biopulping, biobenefication, bioremediation (Classen et al. Recent reports underpin the finding that gut microbial glycerol metabolism leading to the formation of reuterin is an additional source of endogenous acrolein. The third edition of Microbial Ecology of the Oceans features new topics, as well as different approaches to subjects dealt with in previous editions. If the terms are summed (-85. Metabolic engineering allows for the rewiring of basic metabolism to overproduce both native and non-native metabolites. Research tools. Microbial production of resveratrol has been achieved in engineered microbial systems based on the natural biosynthesis pathway of stilbenes. Considerable progress has been made in the microbial production of various plant specialized metabolites over the past decade. Learning Objectives Describe how primary and secondary metabolites can be used in industrial microbiology to obtain amino acids, develop vaccines and antibiotics, and isolate chemicals for organic synthesis. pigments, odorants, and pheromones).
