CULTURE CHARACTERISTICS OF 20 LIGNICOLOUS BASIDIOMYCETES SPECIES THAT SYNTHESIZE VOLATILE ORGANIC COMPOUNDS
Journal Title: Analele Stiintifice ale Universitatii Alexandru Ioan Cuza din Iasi, Serie noua, Sectiunea II a. Biologie vegetala - Year 2013, Vol 59, Issue 2
Abstract
This study aims to identify the lignicolous basidiomycetes species that synthetize volatile organic compounds with potential applications in various industries: food industry, cosmetics and perfumery or in agriculture. These species are among the very few organisms that thanks to their complex enzymatic system can degrade lignin, one of the most abundant and resistant biopolymers. With this purpose in mind, we have collected fruiting bodies from different phytocenoses and the lignicolous basidiomyctes species were identified by their macroscopic and microscopic characteristics. From the context of the fresh fruiting bodies small fragments of dikaryotic mycelium were extracted and inoculated on classic and adapted synthetic media and incubated in the dark at a temperature of 25°C. 20 species of lignicolous basidiomycetes, belonging to 8 families and 3 orders were isolated in pure culture. The isolates were analyzed in vitro and the main characteristics that were observed are: the general aspect of the surface and the reverse of the colonies, the changing in color and the growth rate of the mycelium and also the specific odor which indicates the presence of the organic volatile compounds.
