Abstract:

Wine lees, the residue left behind after racking or bottling of wine, are predominantly composed of dead yeast cells, ethanol, phenolic compounds, and tartrates. Yeast extract (i.e., commercial yeast extract), a highly nutritious powder derived from commercially cultivated yeast biomass, is commonly used in nutrient media as a nitrogen source. In the context of by-product valorization, wine lees could potentially be used to produce a substitute for commercial yeast extract (CYE). In our study we investigated the growth and fermentative ability of two major winemaking microorganisms, Lactiplant

Abstract:

The peel of mangosteen (Garcinia mangostana L.) constitutes a larger proportion of the fruit in comparison to its flesh. The peel extract product manufactured by nutraceutical industries does not require using the fruit flesh. To increase the shelf life and value of the product, the development of a mangosteen powder drink can be carried out. Therefore, this research aims to determine the characterization of initial raw materials and factors influencing consumer preferences for instant mangosteen powder drink to improve the acceptance of the product. The data collected were analyzed through de

The amylolytic fungal strains Rhizopus microsporus and Trichoderma viride with high α-amylase activity were isolated from coconut meat waste and soil from cassava dumpsite respectively. Some factors that affect the secretion of the enzyme were optimized. Optimum amylase production from R. microsporus and T. viride were obtained at pH 7 and 9 at 50OC and 60OC respectively. Five different agro wastes (corn starch, potato starch, rice bran powder, cassava peel powder, wheat husk powder) used as substrates for alternative source of carbon revealed cassava peel to be the best substrate for alpha am

Bacillus subtilis produced a high level of keratinolytic protease using chicken feather powder as substrate. With feather powder as substrate, physical factors such as incubation time, pH and temperature were optimized for increased keratinolytic protease production by Bacillus subtilis. The enzyme production was enhanced when using maltose as carbon source and yeast extract as nitrogen sources. SDS-PAGE analysis indicated

The results indicated that the buffer pair formed when the pH was adjusted to 4.5 stabilized the pH of the medium by sequestering protons
