Light and growth medium effect on Chlorella vulgaris biomass production

Growth Medium Screening for Chlorella vulgaris Growth and Lipid Production

“…The findings indicated that a suitable medium for C. vulgaris cultivation (for mass or small scale culturing), is the major approach to algae products production (Blair et al, 2013) [43]. Nitrogen is the most important nutrients affecting the biomass growth and lipid accumulation (Griffiths & Harrison, 2009;Wang et al, 2014) [44,37].…”

Cultivation Of Microalgae (Chlorella vulgaris) For Biodiesel Production

“…Results in (12) showed that at the recommended (100 %) growth media composition (BBM medium), the algal growth was observed to be linear, however at 50 % composition; the growth followed an exponential trend. Further tests on nutrient concentration effect (nitrogen and phosphorous) have shown that low nitrogen concentrations can also stimulate algal growth.…”

“…Several studies reported the growth of microalgae in different light wavelengths. Red (600-700 nm) and blue lights (400-500 nm) stimulate the growth of microalgae, and the growth rates and lipid content of the microalgae differ with light intensity (12).…”

“…Results in (12) have shown that light wavelength has a noticeable effect on the algal growth rates. Red and green light did not show a positive trend in the growth rates compared to clear and blue light wavelengths.…”

“…Nutrients are required in large quantities, therefore utilization of cheap nutrient sources such as municipal wastewater and other industrial co-products is ideal for algal growth economics. Utilizing wastewater resources to replace growth media may alleviate the cultivation costs to some extent (12).…”
