Análise do crescimento da microalga Chlorella vulgaris em soro do leite

Abstract

Cultivating the microalgae Chlorella vulgaris in whey represents a promising strategy at the intersection of biotechnology and waste management. Chlorella vulgaris, known for its ability to adapt to different substrates, demonstrates promising results in environments enriched with organic carbon from whey. Whey, a byproduct of the dairy industry, provides a nutrient-rich source, including carbon, nitrogen, and minerals, creating ideal conditions for the growth of Chlorella vulgaris. This cultivation results in efficient biomass production, standing out as a profitable strategy for microalgae production and an alternative for the utilization and reduction of the pollutant load in whey. The versatility of this microalga, coupled with the efficiency in utilizing whey, highlights this approach as a significant contribution to the sustainable production of microalgal biomass, with potential applications in nutritional and energy sectors. Therefore, this method not only revalues industrial waste but also drives the search for efficient solutions at the interface of biotechnology and waste management. In this study, the microalga achieved the highest growth rate at a 50% concentration of whey diluted in distilled water.
