ABSTRACT
Several researches have also motivated to enhance the biogas production through co-digestion, which refers to a combination of different wastes as substrates in the fermentation process. In general, biodegradable waste is known as biomass, which refers to the organic material and can be converted into high-value products by microorganisms or their enzymes. Chitinolytic enzyme is another important enzyme can be produced from fish processing waste by bacteria, fungi, yeasts, and viruses. Dairy plants in varying sizes also discharge a large amount of wastewater than any other food industries. Environment-friendly microorganisms are commonly used in bioremediation, which has proved to be effective in lowering industrial waste. Environmental scientists have studied on several processes to remove or detoxify organic and hazardous pollutants, like lead, copper, and cadmium, while bioconversion has aroused as an effective and environmental-friendly technique. Biodegradation is the most effective way of waste management than other methods while production of bioenergy through biodegradation is promising.
