Abstract

Solid state fermentation (SSF) was applied for production of fungal enzyme preparations from Phanerochaete chrysosporium, Aspergillus oryzae, Aspergillus giganteus and Trichoderma virens using cotton seed-coat fragment waste as a carbon source and enzyme inducer. Lignin-holocellulose matrix of cotton seed coat fragment proved to be effective in inducing production of ligninolytic, cellulolytic and xylanolytic enzymes in solid-state fermentation. The effect of the enzymes produced by SSF on greige linen fabric is discussed and evaluated. In the first experiment the hydrolytic and accompanying oxidative enzymes in the buffer extract of the whole SSF cultures were used for fabric treatment. In the second trial, the enzymes produced in situ (whole SSF material-mixture of fungal biomass, residual substrate and enzymes) were used for the treatment. Weight loss, reducing sugar liberation and removal of colouring materials were measured. The results showed that at equal enzyme charges the intact SSF materials were more efficient than the enzyme extracts. Of the six strains evaluated, Ph. chrysosporium VKM F-1767 was the most effective in removing colouring matters from greige linen fabric.
