2023/11/29/ · The following are the enzymes which are majorly used in the food industries and produced by the utilization of fruit and vegetable wastes: 3.1 Amylases. Amylases are starch-degrading enzymes that aid in the hydrolysis of internal alpha 1–4 glycosidic linkages in polysaccharides while preserving the end products’ alpha anomeric structure (Saini et al.
2022/12/12/ · Solid-state fermentation (SSF) is part of the pathway to consolidate waste as a relevant alternative for the valorization of organic waste. The objective of SSF is to produce one or several bioproducts of added value from solid substrates. Solid-state fermentation can use a wide variety of organic waste as substrates thus, it is an excellent
Solid-state fermentation (SSF) is a biotechnological process that uses solid or semisolid matrices as substrates with the necessary amount of water for the growth and metabolism of microorganisms (Singh Nee Nigam and Pandey 2009).. The most important factors for proper fermentation are the inoculum volume of the microorganisms, humidity, temperature, pH,
2016/7/27/ · The bioconversion systems led to the production of 250 mL/kg of ethanol at 90° after distillation of the CDPW juice at 78°. bioethanol was produced by fermentation of date palm fruit waste ...
2020/12/1/ · Abstract and Figures. This study was aimed to produce enzymes by co-culturing of Bacillus megaterium and Saccharomyces cerevisiae using fruit waste as sole substrate in submerge fermentation
2023/8/1/ · Free sugars from fruit wastes were evaluated for the production of poly(3-hydroxybutyrate) (PHB) in Paraburkholderia sacchari fed-batch bioreactor fermentations. Different initial sugar concentration, carbon to inorganic phosphorus (C/IP) ratio, IP addition during feeding and volumetric oxygen transfer coefficient (k L a) were evaluated to promote
2012/10/1/ · Fermentation yielded 670 NL biogas/kg volatile solids (VS) with the CSTR and 550 NL biogas/kg VS with the FBR. The productivities were 3.9 NL biogas/ (L*d) with the CSTR and 3.4 NL biogas/ (L*d) with the FBR. The average methane concentration was approximately 60% for both reactor systems.
Food waste (FW) is an inevitable portion of food eliminated from the food supply chain (FSC). FW is composed of biomass that can be either dumped into sewer lines, landfills, and sea or reutilized for composting, harvesting, bioenergy production, anaerobic digestion, and incineration (Lin and Tanaka 2006).FW includes those components of food items that are
The study explores the effects of different pH ranges (5.5–8) and food to microorganism (F/M) ratios (0.5–2) on the H2 production from fruit and vegetable waste (FVW). The study was performed via dark fermentation of mixed FVW without temperature control. The study highlights the effect of different kinetic parameters, such as lag time (λ), maximum H2
2023/9/25/ · 1. Introduction. For decades, lithium-ion batteries (LIBs) have been the most dominant type of secondary energy storage due to their high energy density, high cyclability and compact size (Or et al., 2020; Li et al., 2018a).The LIBs market in 2021 was valued at USD 41.97 billion and is forecasted to grow to a staggering USD 182.5 billion in 2030, with a
39.4.2 Fermentation of agri-food waste. Fermentation is a process of converting the organic material into various products using different microbes, such as bacteria and fungi. There are several different products that could be produced through fermentation, for example, fuels, chemicals, pharmaceuticals, etc.
2023/10/30/ · Preparing the Fruits for Fermentation. Before starting the fermentation process, it’s important to properly prepare the fruits. This includes washing them thoroughly and removing any stems, seeds, or pits. Some fruits may also need to be chopped or mashed to release their juices.
2020/6/3/ · Abstract. The world’s second-largest producer of fruits is India, and the fruit processing industries generate tons of fruit waste in the form of peels, stones, seeds, and pomace, which comprise about 30–40% of fruit weight. Being high on biological oxygen demand, this waste if left untreated is a potential hazard to the environment.
2018/10/8/ · Their results revealed that the production of alcohol with fermentation of pawpaw fruit waste using baker’s yeast was 2.82–6.60% (v/v) in 72 h of fermentation. Potato peel waste was used for ligninolytic enzymes production like manganese peroxidase, laccase, lignin peroxidase and aryl alcohol oxidase using solid state fermentation by
2017/2/1/ · 1. Introduction. In Chinese cities, fruit and vegetable waste (FVW), a type of municipal solid waste, is generated at a substantial rate of approximately 1.3 million tons per year; however, reports suggest that less than 20% of this waste is properly treated (Shen et al., 2013, Liu et al., 2012).Therefore, new and optimized treatments for FVW are required.
