Twenty-four bacteria and 8 fungi were isolated from 8 different kind industrial producing
sprouts．Molecular identification showed that these 24 bacteria belong to 8 genus（Klebsiella，Enterobacter，
Pseudomonas，Acinetobacter，Pectobacterium，Empedobacter，Delftia and Comamonas），and were all
G-，and 7 of them were not typical plant pathogen，except Pectobacterium．Four genus（Acinetobacter，
Enterobacter，Klebsiella and Pseudomonas）were isolated from 2 or over 2 sprouts，and the other 4 genus
were only isolated from one kind sprout．The result implied that there was host specialization in these bacteria．
Eight fungi belong to 3 genus（Fusarium，Alternaria and Rhizopus）．Fungi isolated from the other 6 sprouts
all belong to Fusarium，Alternaria and Rhizopus fungi were only isolated from water spinach and radish sprout，
respectively．The water spinach and radish sprouts showed different rot symptoms after inoculated by 4 bacteria，
and the black soya bean sprouts showed different rot symptoms after inoculated by 3 fungi．These results indicated
that microorganism from environment during production process could also cause sprout diseases．
