Biotechnological exploitation of Antarctic-derived fungi

Abstract

The Antarctic continent is characterized by restrictive environmental conditions of climate, habitat and biogeography. The main organisms adapted to the harsh conditions of this environment are the micro-organisms, which have potential application in several biotechnological processes. Among the enzymatic arsenal of fungi stand out ligninases, cellulases, xylanases, lipases and proteases that have wide application in various sectors of socio-economic importance. The present work aims to use the 350 fungi (~250 filamentous fungi and 100 yeasts) maintained in the research collection of Microbial Resources Division (CPQBA / UNICAMP), which were recently isolated from samples of terrestrial and marine Antarctic ecosystems in order to: a) select fungi able to produce environmental and/or industrial enzymes; b) produce and optimize the production of such enzymes by the selected fungi; c) characterize biochemically the enzymes highly produced; d) detect and characterize the genes that code for the production of the highly produced enzymes; e) taxonomically identify fungi that have potential for biotechnological applications and; f) deposit the isolates identified in the Collection of Antarctic Micro-organisms structured within the scope of Brazilian Collection of Microorganisms Environment and Industry - CBMAI (CPQBA / UNICAMP). It is worth to mention that new yeast strains are being obtained from four different samples of marine sediments, which will also be prospected and studied in this work. (AU)
