AbstractObjective:The aim of this work was to study the optimal cultivation conditions for β-galactosidase production byBacillus licheniformisATCC 12759.Materials and methods:The screening of β-galactosidase production fromB. licheniformisATCC 12759 was performed by solid state fermentation method on media rich with rice bran (RB). Different factors were tested for the optimization of β-galactosidase production.Results:Certain fermentation parameters involving incubation time, incubation temperature, inoculum level, moisture content, initial pH, agitation speed, size of fermentation medium and optimum temperature of β-galactosidase activity were studied separately. Maximal amount of β-galactosidase production was obtained when solid-state fermentation (SSF) was carried out using RB, having inoculum level 35%, moisture content of 20%, initial pH 7.5 at 37°C for 48 h.Conclusion:Results indicated that optimal fermentation conditions play a key role in the maximum production of β-galactosidase fromB. licheniformisATCC 12759. This study shows the potential of the studied enzymes to be promoting candidates for the degradation of lactose and production of important bioproducts.

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.
