Effect of elevated temperature on Trichoderma viride SL-1 in solid state fermentations SunTao LiuBeihui LiuDeming LiZuohu 2017 Cellulase productions in solid state fermentation (SSF) by Trichoderma viride SL-1 were conducted in a column. Periodically oscillating the temperature in the range of 30-50¡C in symmetrical or asymmetrical modes had no adverse effect on productivity. Effective activation of spore germination was found when the spores were treated twice at 30¡C for 30 min. The results are useful in the performances of SSF processes.
