Fermentation Parameters

In this study, agriculture waste palm empty fruit bunch (EFB) was used as carbon/cellulose source in solid state fermentation for cheaper cellulase production. Fermentation operation parameters, such as: solid to liquid ratio, temperature, and pH, were varied to study the effect of those parameters towards crude cellulase activity. Two different fungi organisms, Trichoderma viride and Trichoderma reesei were used as the producers. Extracellular cellulase enzyme was extracted using simple contact method using citrate buffer. Assessment of the extracted cellulase activity by filter paper assay showed that Trichoderma viride is the superior organism capable of producing higher cellulase amount compared to Trichoderma reesei at the same fermentation condition. The optimum cellulase activity of 0.79 FPU/g dry substrate was obtained when solid to liquid ratio used for the fermentation was 1:1, while the optimum fermentation temperature and pH were found to be 30 °C and 5.5, respectively. The result obtained in this research showed the potential of EFB utilization for enzyme production. Copyright © 2018 BCREC Group.

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.

Cellulases, among many enzymes, have been highlighted in several areas of expertise, such as food, textiles, pulp and paper and wastewater treatment of effluents and residues. There is also the challenge of producing biofuels, where currently cellulases have been widely applied in the production of cellulosic ethanol, where it is used during the stage of hydrolysis of lignocellulosic biomass for conversion of cellulose to glucose. Studies have been developed in order to produce this enzyme through a process of solid state fermentation from lignocellulosic agroindustrial wastes, thus reducing the cost of enzyme production, and adding value to the residue. The aim of this work was to produce cellulases from the stalk of the cashew bagasse using Trichoderma reesei LCB 48. The study of the cellulase production was performed using 22 factorial design with central point in quadruplicate. The washed stalk of the cashew bagasse inoculated with T. reesei was evaluated for the production of cellulases with initial moisture contents of 45, 55 and 65% and in the presence of inorganic nitrogen ((NH4)2SO4) at concentrations 0.5, 0.75 and 1%. The fermentation was developed over 238 hours, and during this period the parameters analyzed were pH, moisture, AR and enzyme activity expressed in CMCase. Peak production of cellulase enzyme expressed in CMCase was achieved with 238 hours which value was 0.71 U/g (0.095 U/mL), under the conditions of 45% initial moisture content and 1% of nitrogen source. This activity was obtained in only one stage of the biotechnological process, the solid state fermentation; the next ones are concentration and purification. The using of experimental design methodology allowed us to observe the initial substrate moisture is the determining variable in the production of enzymes CMCases, and the minimum moisture level (45%) showed the highest production values of CMCase.

Solid-state fermentation (SSF) is a promising technology for producing bioproducts from organic wastes. The objective of this study is to assess the feasibility of using digestate as substrate to produce hydrolytic enzymes, mainly cellulase and xylanase, by exploring three different inoculation strategies: (i) SSF with autochthonous microbiota; (ii) non-sterile SSF inoculated with Trichoderma reesei and (iii) sequential batch operation to select a specialized inoculum, testing two different residence times. Native microbial population did not show a significant cellulase production, suggesting the need for a specialized inoculum. The inoculation of Trichoderma reesei did not improve the enzymatic activity. On the other hand, inconsistent operation was achieved during sequential batch reactor in terms of specific oxygen uptake rate, temperature and enzymatic activity profile. Low cellulase and xylanase activities were attained and the main hypotheses are non-appropriate biomass selection and some degree of hydrolysis by non-targeted proteases produced during fermentation.
