Beta-glucosidase (BGL) is an enzyme involved in the hydrolysis of cellulose and plays an important role in many biological processes. This enzyme is widely available in animals, plants, and microorganisms. Expression of the recombinant enzyme in Escherichia coli is considered a suitable choice for high production via a fast growth rate and feasible manipulation.

In this study, sweetened black and green tea were utilized as substrate for kombucha fermentation. Linden, lemon balm, sage, echinacea, mint, and cinnamon infusions were added to kombucha to design a novel beverage with improved functional and organoleptic characteristics. After fermentation, the antioxidant capacity (AC) of the kombucha increased by 13.96% 2,2-diphenyl-1- picryl-hydrazyl-hydrate (DPPH), 48.90% ferric reducing antioxidant power (FRAP), and 55.54% cupric reducing AC (CUPRAC).

Three Trichoderma isolates (THDU-1, THDU-2, and THDU-3) were isolated from the root zone area of healthy bananas on the farm in Ba Thuoc district, Thanh Hoa province. All of these isolates showed high inhibitory activity against soil borne diseases Rhizoctonia solani and Sclerotium rolfsii. Our study proposed a protocol of Trichoderma mass multiplication using rice media based on solid substrate fermentation (SSF) to produce commercial product of Trichoderma.

The production of cellulases is an important strategy for the development of sustainable second-generation ethanol production processes. The present study was undertaken to select cheap and efficient agricultural residue suitable for cellulase production using fungus Humicola insolens. Six different agricultural residues viz., paddy straw, soybean pod husk, sugarcane bagasse, groundnut shells, corn stalks and pigeonpea pod husk were used as substrate in the solid state fermentation medium.

Amylase producing thermophilic bacterial strain was isolated from Jeori hot water spring, Rampur Bushahr of Shimla district of Himachal Pradesh, India and identified as Bacillus thuringiensis J2 using 16S rRNA gene sequencing and deposited in NCBI gene bank vide accession number |KY990713|. Medium components and process parameters were optimized with respect to substrate concentration, carbon sources, nitrogen sources, incubation period, pH and temperature for an enhanced amylase production.

The present results reported that leaves and twigs of AN contained higher levels of CP, FAT, and NFE than in AH treatments. They had significant (P< 0.05) effects on dry matter intake (DMI), lambs' body weight, and digestibility. In contrast, Degradability, higher gas production and in vitro fermentation range of BH to that these substrates had a higher nutritional value than the other browse species. Lambs receiving BH consumed (P< 0.05)more feed compared to those received AH or AN.
