Assimilation of lemonade-processing wastewater by yeasts.
Of the five species of yeasts examined in shake-flask studies at 30 degrees C, only Candida utilis and Saccharomyces fragilis gave higher cell yields (>2.5 g /liter) in 32 h and reduced approximately 87% of the biological oxygen demand in lemonade-processing wastewater fortified with 0.05% ammonium sulfate and 0.01% potassium phosphate. The latter, however, settled more rapidly than the former.
