Application of Anabaena azotica- and Chlorella pyrenoidosa-Based Algal Biotechnology in Green Production of Algae-Rich Crataegi fructus.

Nitrogen-fixing Anabaena and Chlorella pyrenoidosa algal biotechnology are known as new agricultural inputs due to their characteristics and are widely used in the field of agricultural planting. This paper discusses the application of algal biotechnology based on nitrogen-fixing Anabaena sp. The advantages of algal biotechnology based on nitrogen-fixing Anabaena and Chlorella pyrenoidosa in terms of yield, sugar content, polyunsaturated fatty acid content, and high-quality yield of hawthorn were compared.
