Evaluation of Growth and Production of High-Value-Added Metabolites in and Grown on Crude Glycerol under Heterotrophic and Mixotrophic Conditions Using Monochromatic Light-Emitting Diodes (LEDs).

This study aimed to examine the impact of crude glycerol as the main carbon source on the growth, cell morphology, and production of high-value-added metabolites of two microalgal species, namely and , under heterotrophic and mixotrophic conditions, using monochromatic illumination from light-emitting diodes (LEDs) emitting blue, red, yellow, and white (control) light. The findings indicated that both microalgae strains exhibited higher biomass yield on the mixotrophic growth system when compared to the heterotrophic one, while generally performed better than . In mixotrophic mode, the use of different monochromatic illumination affected biomass production differently on both strains.

Continuous Culture of on Biodiesel Derived Glycerol under Mixotrophic and Heterotrophic Conditions: Growth Parameters and Biochemical Composition.

As crude glycerol comprises a potential substrate for microalga fermentation and value added products' biosynthesis, was grown on it under heterotrophic and mixotrophic conditions and its growth kinetics were evaluated in a continuous system under steady state conditions. Increasing initial glycerol concentration (from 30 to 50 g/L) in the heterotrophic culture led to reduced biomass yield () and productivity (), but favored lipid accumulation. Under heterotrophic conditions, the microalga was found to grow better (biomass up to 7.

Effects of Monochromatic Illumination with LEDs Lights on the Growth and Photosynthetic Performance of in Photo- and Mixotrophic Conditions.

This study examined the effects of monochromatic illumination (blue, red, green and yellow) employing light-emitting diodes (LEDs), trophic conditions (photoautotrophic and mixotrophic), and nitrogen availability (high and low peptone concentration) on the growth and biochemical composition of . The results revealed that mixotrophic conditions did not favor , giving lower growth rates compared to heterotrophy (dark conditions). However, mixotrophy gave significantly higher growth rates compared to photoautotrophy.
