TL;DR: De-oiled Jatropha curcas seed cake, a plentiful by-product of biodiesel industry was used as substrate for the production of a useful xylanase from Sporotrichum thermophile in solid state fermentation, which seem potentially useful in the food industries.

TL;DR: In this paper, the effects of moisture level, particle size and inoculum concentration on enzyme synthesis from P. chrysogenum were investigated using a fungal culture of Penicillium chryogenum.
Abstract: Summary Solid-state fermentation (SSF) was carried out using corncob leaf (CL), rye straw (RS), wheat straw (WS) and wheat bran (WB) as substrates for a-amylase production by a fungal culture of Penicillium chrysogenum. The effects of moisture level, particle size and inoculum concentration on enzyme synthesis from P. chrysogenum were investigated. Optimal moisture levels of substrates were 75, 65, 65 and 55 % for CL, WS, WB and RS substrates, respectively. Optimal particle size and inoculum concentration for the production of a-amylase were: >1 mm, 20 %; >1 mm, 20 %; 1 mm, 20 % and >1 mm, 30 % for CL, WS, WB and RS, respectively. WB showed the highest enzyme production with 160 U/mL under optimum conditions. The other enzyme activities were 28, 49 and 45 U/mL using CL, RS and WS, respectively.

TL;DR: Comparisons of the enzymes production under the same SSF conditions indicated that FPase produced by A. niger USM AI 1 was about 35.3% higher compared to Trichoderma reesei, showing that the performance of this newly designed SSF bioreactor is acceptable and potentially used as prototype for larger-scale biore actor design.
Abstract: Novel design solid state bioreactor, FERMSOSTAT, had been evaluated in cellulase production studies using local isolate Aspergillus niger USM AI 1 grown on sugarcane bagasse and palm kernel cake at 1 : 1 (w/w) ratio. Under optimised SSF conditions of 0.5 kg substrate; 70% (w/w) moisture content; 30∘C; aeration at 4 L/h·g fermented substrate for 5 min and mixing at 0.5 rpm for 5 min, about 3.4 U/g of Filter paper activity (FPase) was obtained. At the same time, comparative studies of the enzymes production under the same SSF conditions indicated that FPase produced by A. niger USM AI 1 was about 35.3% higher compared to Trichoderma reesei. This shows that the performance of this newly designed SSF bioreactor is acceptable and potentially used as prototype for larger-scale bioreactor design.
