G. Flachowsky et al., In sacco degradability of wheat straw residues after growing of Lentinus tuberregium (Fr.) Fr., J APPL AN R, 20(1), 2001, pp. 33-40
The tropical fungus Lentinus tuberregium was cultivated on steamed wheat st
raw at various cultivation conditions (time, temperature, Moisture). After
harvesting of sclerotia/fruit bodies straw residues were directly weighed,
analysed and prepared for in sacco Measurements with three rumen fistulated
sheep. Lignin content of wheat straw decreased from 7.8% to 2.4% of straw
residues. The lignin loss varied between 59.0 and 89.7% and was more select
ive than the carbohydrates. Effective degradability of dry Matter of wheat
straw residues at the passage rate of 0.04 per h increased from 32.2 (untre
ated control) up to 64.4%. The results show that Lentinus tuberregium degra
ded lignin and improved dry Matter degradation Of residues in the rumen. Fu
rther investigations seem to be necessary to optimise the conditions of sol
id-state fermentation.
