2008 m. Nr. 3 Destruction of hemicellulose in rye straw by micromycetes
The ability of micromycetes to destruct hemicellulose and xylane – the main hemicellulose polysaccharide, – in herbal waste was investigated. We found that hemicellulose was most destructed after 60 days of micromycete cultivation. Its quantity after Chaetomium globosum cultivation was reduced down to 6.35%, Myrothecium verrucaria to 7.22%, Galactomyces geotrichum to 7.92% and Mortierella verticillata to 7.99%. The change of hemicellulose content was least after Sporotrichum pruinosum and Acremonium strictum cultivation. The numbers of fungi were 2.3 and 2.5 times lower than in the control sample. The more intensive xylane destruction in liquid fermentation conditions after 15 and 20 days was determined in samples with Myrothecium verrucaria (the content of sugars increased up to 37.3 and 75.93 mg%) and Galactomyces geotrichum (26.4 and 38.83 mg%). Keywords: micromycetes, hemicellulose, xylan |
