OPTIMIZATION OF CULTIVATION CONDITIONS OF A NEWLY ISOLATED STRAIN CHLORELLA SP. LH2 FOR COOKING COCOON WASTEWATER TREATMENT
Cooking cocoon wastewater contains large quantities of biodegradable nutrients such as nitrogen, phosphorous, and other compounds that microalgae can consume for their growth. In this study, locally isolated Chlorella sp. LH2 was investigated as a means to remove contaminants in wastewater treatment...
