2023/9/24/ · 4.3.1 Oriental Fermented Food. Mixed cultured fermentation is noticeably more common in the far east than in the western world. These include countries like Japan, India, Taiwan, China, Korea, Pakistan, Thailand, and Indonesia (Ray et al., 2014).In oriental fermentation, a few genera and species of microorganisms are selected, which in the
2020/4/29/ · Moisture is required for an SSF to be carried out in the best way. De Souza SR, Da Silva R, Gomes E (2004) Pectinase production by fungal strains in solid-state fermentation using agro-industrial bioproduct. Braz Arch Biol Technol 47(5):813–819 ... (1998) pH regulation in solid state culture through the initial ratio between oxidized
moisture content and water activity (α w). During the fermentation, too much water would compact the sub-strate, impede oxygen transfer, and favor contamination. On the other hand, too little moisture creates adverse conditions which inhibit growth and enzymes especially hydrolase production and limit the transfer of nutrients.
2015/10/8/ · Here, we discuss ten general strategies behind the successful development of industrial microbial strains through systems metabolic engineering. We illustrate their implementation using several
Industrial Fermenters. Fermenters are containers used to grow (‘ culture ’) microorganisms like bacteria and fungi in large amounts. These can then be used for brewing beer, making yoghurt and mycoprotein and other processes not involving food, like producing genetically modified bacteria and moulds that produce antibiotics (e.g. penicillin
2015/1/1/ · The top layer (80% butanol and 20% water) is returned to the butanol column, and the bottom layer (4% butanol and 96% water) is returned to the beer column. Approximately 35,000 lb stream is consumed for every ton of solvents produced. Fig. 24.22. Process flow sheet of butanol-acetone-ethanol fermentation.
2023/7/29/ · Withering as a first fermentation step has a significant impact on final product sensory attributes as it induces certain biochemical interactions that play a pivotal role in product aroma (Soheili-Fard et al. 2015).Prior to any fermentation steps, the fresh green tea leaf is composed of 30% catechins while other compounds belong to other
2021/6/9/ · Initial moisture and water activity, the nature and size of the solid particles, inoculum volume, and additional nutrients also affect the efficacy of the solid-state fermentation [92,98]. All these factors must be optimized applying strategies, which include factorial design and response surface methodologies, artificial neural network and
Solid-state fermentation (SSF) is defined as the growth of microorganisms in moist, nonsoluble substrate with low water content [1,2]. SSF is employed in the production of enzymes such as pectinases [3], cellulases, xylanases and lipases [4], biopesticides, edibles products, and a wide variety of secondary metabolites [1].
2023/6/29/ · Comparing fermentation media, 2SMol presented a final pH of 5, lower than 5.5 obtained for industrial molasses. For the fermentation cycles, a similar wine-pH pattern was observed with a decrease
2015/12/28/ · The document discusses bioreactors, also known as fermenters. It provides information on: (1) Bioreactors use living cells or enzymes to generate a higher value product from a lower value substrate. They are commonly used for food processing, fermentation, and waste treatment. (2) Bioreactors can be classified based on the agent
2022/3/8/ · A fermenter (bioreactor) is a closed vessel with sufficient aeration, agitation, temperature, and pH regulation arrangements and a drain or overflow vent to extract the waste biomass along with its products from cultured microorganisms. The fermenter is intended for the production of biological products. The fermenter’s design and mode of
2003/3/1/ · This aseptic fermenter was used for different purposes and to improve simultaneous control of temperature and moisture content. Although heat transport to the bioreactor wall was improved, this device becomes inefficient for larger volume [11] because heat removal only through the wall becomes increasingly inefficient as the volume
