The S. limacinum biomass productions were 9.52±0.08 g L-1 (AJ), 8.70± 0.05 g L-1 (GJ), and 8.58±0.02 g L-1 (SM). C. cohnii produced biomass as 3.45±0.06 g L-1 (GJ), 1.52±0.04 g L-1 (AJ), and 1.35±0.02 g L-1 (SM). The fruit juice-based media enhanced biomass production. It was observed that the lipid production of S. limacinum increased by 17.6% in the medium with apple juice (2.54±0.02 g L-1), while this increase was 65.3% in the grape juice-based medium (3.57±0.02 g L-1). The addition of apple juice caused an increase in the lipid amount 1.9 times higher (0.23±0.02 g L-1), while grape juice induced 5.3 times more lipid production in C. cohnii culture (0.50±0.03 g L-1). The study emphasized that these wastes or by-products can be considered as sustainable and financially supportive solutions to be alternatives to carbon sources in production with S. limacinum and C. cohnii cultures.
