Abstract: The microbes found in Pu-Er tea, microbes in relation to the post fermentative processing, microbes in relation to Pu-Er tea quality and the growth traits of main microbes were reviewed . It was pointed out that fundamental studies on the post fermentative microbes of Pu-Er tea should be strengthened; a bank of the post fermentative microbes of Pu-Er tea should be established; and a systematic study on those microbes with identified impacts on Pu-Er tea quality should be given high priority .

Key words: Pu- er tea
