TL;DR: A solid state fermentation system for the production of ethanol from apple pomace with a Montrachet strain of Saccharomyces cerevisiae is described in this paper, where the yields of ethanol varied from about 29g to more than 40g per kg of apples, depending on the samples fermented.
Abstract: A solid state fermentation system for the production of ethanol from apple pomace with a Montrachet strain of Saccharomyces cerevisiae is described. The yields of ethanol varied from about 29g to more than 40g per kg of apple pomace, depending on the samples fermented. Separation of up to 99% of the ethanol from spent apple pomace was achieved with a rotary vacuum evaporator. The results of this study indicate that the alcoholic fermentation of apple pomace might be an efficient method of alleviating waste disposal problems with the concomitant production of ethanol.

TL;DR: As found with wheat straw, all other substrates tested were degraded more slowly byDichomitus squalens than bySporotrichum pulverulentum, and the best method to supress potential competitors was to heat the substrate to 90°C for 24 h.
Abstract: The fermentation profiles ofSporotrichum pulverulentum andDichomitus squalens showed distinct differences.D. squalens digested the substrate more slowly thanSporotrichum pulverulentum. The relative degradation rates of total organic matter and lignin also differed considerably.

TL;DR: Trichoderma harzianum was selected from 30 strains of cellulolytic fungi with the aim of producing cellulases by solid state fermentation of lignocellulosic substrates with special attention to cellulase production, apical growth and conidia production.
Abstract: Trichoderma harzianum was selected from 30 strains of cellulolytic fungi with the aim of producing cellulases by solid state fermentation of lignocellulosic substrates. Special attention was paid to cellulase production (i.e. carboxymethylcellulase and filter paper activity), apical growth and conidia production. Under the conditions of our experiments, T. harzianum exhibited the highest cellulasic activities with 1,315 IU/l of carboxymethyl cellulose and 80 IU/l of filter paper activity. Apical growth (1 mm/h) and yield of conidial production (3.25 x 10(10) conidia/g of substrate dry weight) were also valuable characteristics of this strain in the use of solid state fermentation.
