Lignite fly ash (LFA) is the by-product of thermal power stations. The Blue Green Algae Spirulina platensis grows well in the alkaline pH of the LFA, which also contains an array of micronutrients and macronutrients that aid the growth of Spirulina platensis.

In India, Neyveli Lignite Corporation (NLC) liberates tonnes of LFA as a waste product, which highly pollutes the local soil and water.

The present work was planned to utilize the LFA at different concentrations for the laboratory cultivation of Spirulina platensis in order to recycle LFA waste and minimize environmental pollution.

In this study, Spirulina platensis was cultivated in conical flasks containing Zarrouk’s medium alone [SP1] and Zarrouk’s medium with three different concentrations of LFA supplementation (0.5 g/l [SP2], 1.0 g/l [SP3], and 1.5 g/l [SP4]) .

Among the four different supplementations used, SP4 which contains 1.5 g Lignite fly ash in one litre of Zarrouk’s medium highly induces the growth and protein content of Spirulina platensis when compared to other supplementations.
