Novel combination of feed enzymes to improve the degradation of Chlorella vulgaris recalcitrant cell wall

Research Areas: Science & TechnologyABSTRACT - In this study, a rational combination of 200 pre-selected Carbohydrate-Active enzymes (CAZymes) and sulfatases were tested, individually or combined, according to their ability to degrade Chlorella vulgaris cell wall to access its valuable nutritional compounds. The disruption of microalgae cell walls by a four enzyme mixture (Mix) in comparison with the control, enabled to release up to 1.21g/L of reducing sugars (p<0.001), led to an eight-fold increase in oligosaccharides release (p<0.001), and reduced the fuorescence intensity by 47% after staining with Calcofuor White (p<0.001). The Mix treatment was successful in releasing proteins (p<0.001), some MUFA (p<0.05), and the benefcial 18:3n-3 fatty acid (p0.05), total carotenoids were increased in the supernatant (p<0.05) from the Mix treatment, relative to the control. Taken together, these results indicate that this four-enzyme Mix displays an efective capacity to degrade C. vulgaris cell wall. Thus, these enzymes may constitute a good approach to improve the bioavailability of C. vulgaris nutrients for monogastric diets, in particular, and to facilitate the cost-efective use of microalgae by the feed industry, in general.info:eu-repo/semantics/publishedVersio

Cole, Randall Knight

Memorial Statement for Professor Randall Knight Cole, M.S., Ph.D. (1912-2006) who was Assistant Professor (1931), Professor (1950) of Animal Breeding and Poultry Husbandry, and Emeritus Professor (1973) of Genetics in the College of Agriculture. After retirement, he continued to maintain an office in the Department of Poultry and Avian Diseases until 1996 when he transferred to the Department of Microbiology and Immunology in the College of Veterinary Medicine. "Professor Cole's major contributions to science were associated with the role of genetics in disease resistance and susceptibility." He also "taught courses in genetics of the fowl and avian anatomy and participated in teaching of the introductory course in poultry diseases." The memorial statements contained herein were prepared by the Office of the Dean of the University Faculty of Cornell University to honor its faculty for their service to the university
