In 2019, a staggering 931 million tons of food went to waste, which is equal about 17% all the available in stores. Dealing with this waste and managing wastewater from various industries will be among world’s top challenges soon. This because global population expected grow around 9 billion people by 2050. Food processing effluent characterized valuable material considerable concentrations, including proteins lipids low concentrations heavy metals toxicants. Developing an integrated management system for food-processing should focus on recovering abundant resources, improving economic value process, mitigating organic contaminant effluent. state-of-the-art review processes industry. The latest treatment different sectors reviewed. encompass physicochemical recovery techniques, such as precipitation, membrane technology, solvent extraction, foam fractionation, adsorption, aqueous two-phase systems. Additionally, it delve into bio-treatment that leverage microorganisms and/or enzymes utilize nutrients found cost-effective substrates production products. includes detailed examination microalga biomass within Finally, put forward future research directions aimed at integrating principles circular economy developing comprehensive

This study aims to produce a mix of enzymes through Solid State Fermentation (SSF) raw materials. Four different, easily available, agro-industrial wastes were evaluated as SSF substrates for production by Cryphonectria parasitica (Murr.) Barr. environmental strains named CpA, CpB2, CpC4, and CpC7. Among the tested wastes, organic wheat bran human use animal feed better supports C. growth protease without any supplements. SDS-PAGE analyses highlighted presence three bands corresponding an extracellular laccase (77 kDa), endothiapepsin (37 carboxylesterase (60.6 kDa). Protease, laccase, esterase activities in 15 days, showing maximum activity at day 9 (3955.6 AU/gsf,). Conversely, best was achieved after days. The hypovirulent CpC4 strain showed highest (93.8 AU/gsf 2.5 U/gsf, respectively). These results suggest feasibility large-scale industrially relevant process on low value

Alkaline proteases are widely used in industrial processes due to their high pH tolerance and thermal stability. In present work, the protease producing ability of Bacillus strains (Bacillus subtilis PTCC 1254, B. 1156 1715) was studied. 1254 showed highest proteolytic activity therefore, strain selected as biological agent submerged fermentation. Cell growth kinetic model investigated using Malthus Logistic equations, which were relatively well fitted experimental data. The maximum specific rate for models 0.187 0.377 h-1, respectively. optimum culture conditions defined follows: 9, temperature 37°C, fermentation time 72 h, agitation speed 150 rpm 4% inoculum with medium contained 1 g/l CaCl2, 0.6 K2HPO4, KH2PO4, 0.2 MgSO4.7H2O, 2 sugarcane bagasse 4 corn bran carbon nitrogen sources. A 25% v/v wastewater containing starchy waste main substrate. Under conditions, alkaline 117.43 U/ml achieved. Also, obtained able remove blood stain from cotton fabric hydrolyze gelatin X-ray film. Thus, this potential applications detergent photographic industries.
