Abstract

Microalgae is an essential source of renewable bioenergy like biofuels and biohydrogen production due to their high lipid content and rapid growth rate. These eukaryotic organisms exist in an array of habitats, encompassing photobioreactors, closed ponds, and open ponds. But in a photobioreactor or closed system, which provide controlled environment for the cultivation of microalgae a number of variables must be optimized. Because various physio-chemical factors i.e. nutrient availability, light intensity, temperature, pH, mixing/aeration, and salinity, affecting microalgal growth, proliferation, and morphology. However, techno-economic improvements can be made in optimizing and controlling the growth phase of biomass processing. Analysing every factor influencing algae growth and talking about the favourable conditions, strategies and methodology to optimization of factors to achieve better results is the main goal of this review paper. This review aims to serve as a valuable resource for future researchers or anyone who interested to produce maximum algae without any obstruction. A novel aspect of this research is the employment of how to optimize algal growth by adjusting various parameters in a photo bioreactor to improve large-scale cultivation productivity of algae. Thus, the present study aims to investigate factors affecting algae growth and their optimizing methodology which is based on the literature’s findings.
