What are the main microorganisms for biological phosphorus removal? How to realize biological phosphorus removal?

Mainly bacteria and fungi. Bacteria: Pseudomonas, Buddleja, Arthrobacter, Corynebacterium, Flavobacterium, Xanthomonas, Mycobacterium, Thiobacillus, etc. Fungi include Aspergillus, Penicillium, Trichoderma, Yeast, etc.

Algae can also degrade organophosphorus, such as phosphorus bacteria and parathion.

There are two main ways to degrade phosphorus: one is that microorganisms themselves contain enzyme genes that can degrade phosphorus. The other is that there is no enzyme system for degrading phosphorus by microorganisms themselves. When phosphorus enters the environment, due to the survival needs of microorganisms, the genes of microorganisms recombine or mutate in the process of adapting to the environment, resulting in a new enzyme system for degrading phosphorus.
