ajst-1438	Huang, Luwen; Zhu, Liping	Research Progress of Natural Edible Blue Pigment	2022	6	.pdf	application/pdf	5275	293	44	There is also some research on the extraction of natural blue pigments from fungi, which can be grown in a short period of time and can be easily cultured to produce high density cultures, many of which are aromatic polyketides produced during secondary metabolism, and could be an additional source of natural blue pigment production.[18,34] . Although research on the use of microorganisms to extract natural blue pigments still ushers in many problems such as few sources of strains, culture protocols and isolation and purification methods have not yet reached the ideal requirements, but compared with other commonly used methods, the pigments produced by microbial fermentation processes still have many advantages, such as high production efficiency, large culture scale, not affected by climatic and environmental factors, which all make microorganisms as a natural blue pigment This makes microorganisms as a source of natural blue pigment provide a broader development prospect[36] .	cache/ajst-1438.pdf	txt/ajst-1438.txt
