“…It clearly states that consortium of bacteria has improved the quality of methane produced and have the reduced incubation period of 5 days rather than 10 days for control. The four steps in AD are a complete package for the removal of COD toxicity from industrial wastewaters [66]. From hydrolysis to methanogenesis each step works in a unique way to reduce or decompose macro molecules/polymers into smaller molecules/monomers.…”

The Baker yeast industry wastewater is a substantial environmental concern because of industrial contamination, representing a large reservoir of untapped resources. Anaerobic digestion (AD), a multi-stage biological process, can promote sustainability by producing methane (CH4) from baker’s yeast effluent. This manuscript presents a novel method for isolating bacterial strains from animal remnants and effluent produced during baker's yeast manufacturing. The method is intended to preferentially discover bacterial strains that not only can survive but also show increased growth and metabolic activity in particular environmental circumstances. The bacterial consortia, which was kept separate, not only reduced the incubation duration by five days but also decreased BOD and COD levels by 45% and 51.3%, respectively. Additionally, it increased the purity of methane to 73%. This technique proposes a hopeful method for treating industrial effluents with high levels of COD and BOD, which is in line with the objective of achieving zero discharge and promoting water recycling. AD as compared to membrane filtration, coagulation, electrocoagulation, ozonation, aerobic digestion is feasible and economical process. Sustainability is ensured by production of methane and wastewater treatment.
