Fungi isolated from olive ecosystems and screening of their potential biotechnological use.

This study investigated the fungi diversity of fresh olive (Olea europaea L.) fruits, olive paste (crushed olives) and olive pomace (solid waste) and screened and quantified enzymatic activities with biotechnological applications. Fungi were randomly isolated from olive cultivars from Castilla La Mancha region (Spain).

Extracellular beta-glucosidase production by the yeast Debaryomyces pseudopolymorphus UCLM-NS7A: optimization using response surface methodology.

beta-Glucosidase production by Debaryomyces pseudopolymorphus UCLM-NS7A using a simple nutrient medium containing cellobiose was evaluated under several biochemical and physiological parameters in submerged fermentation. Enzyme induction was also examined using different carbon and nitrogen sources. Cellobiose and ammonium nitrate were the best C and N sources to enhance beta-glucosidase production.
