Chlorella vulgaris has attracted the attention of researchers since the 1930s. The first attempts at industrial use of Chlorella were so promising that it was dubbed a superfood. However, scaling up production resulted in rising economic costs that were disproportionate to the final product. This led to Chlorella being forgotten for many decades. A new surge of interest arose in the early 21st century, when methods were developed to grow Chlorella at significantly lower costs. One effective way to quickly increase Chlorella biomass is the use of growth stimulants. In our laboratory, indomethacin and humic acids were studied as such stimulants. Adding these substances to Chlorella culture media accelerated growth by 10-20 times. Considering the small quantities of these substances required to enhance growth and their low cost, this technology will significantly reduce production costs when growing Chlorella and make the process more economically feasible.
