Utilization of poultry manure extract in mixotrophic cultivation of Auxenochlorella protothecoides: effect of glucose enrichment on biomass growth and biochemical composition

Introduction

Significant amounts of poultry manure (PM) are produced due to intensification of agricultural production systems. Nutrient recovery and reutilization from agro-industrial wastes in the framework of the circular economy has thus received increasing attention. PM is rich in nutrients and protein content which renders it ideal as a low-cost microalgae growth medium. Microalgae can provide a valuable source of biomass due to their rapid growth rates and ability to grow in various substrates under heterotrophic or mixotrophic conditions. Mixotrophic cultivation could enhance the productivity by utilizing both inorganic and organic carbon substrates.
