Production and immobilization of enzymes by solid-state fermentation of agroindustrial waste.

The recovery of by-products from agri-food industry is currently one of the major challenges of biotechnology. Castilla-La Mancha produces around three million tons of waste coming from olive oil and wine industries, both of which have a pivotal role in the economy of this region. For this reason, this study reports on the exploitation of grape skins and olive pomaces for the production of lignocellulosic enzymes, which are able to deconstruct the agroindustrial waste and, therefore, reuse them in future industrial processes.

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).

Yeast biodiversity from oleic ecosystems: study of their biotechnological properties.

The aim of this study was to know the yeast biodiversity from fresh olive (Olea europaea L.) fruits, olive paste (crush olives) and olive pomace (solid waste) from Arbequina and Cornicabra varieties. Yeasts were isolated from fruits randomly harvested at various olive groves in the region of Castilla La Mancha (Spain).
