Growth of rhizopus oligosporus in sago effluent at different aeration

In recent years. there are increasing levels of pollution caused by industrial wastewater. Sago effluent discharged into the river contains hazardous compound, toxic chemical and organic materials. In order to overcome this problem, organic materials from sago effluent must be removed by using subme...
