Abstract: The strains No.1834 and No.1835 were isolated from soil samples collected in Guilin, China. They were found to produce two different polyether antibiotics which is effective in preventing and controlling the chicken diseases caused by Emeria tenella.Based on their morphology and chemical composition of cell wall,they are identified to belong to the genus Streptomyces. In comparison with all the known species of Streptomyces, the strains seem to resemble Streptomyces hygroscopicus subsp. duam-yceticus Seino,S. hygroscopicus subsp. aabomyceticus Seine et al., S. hygrospinosus Yan et al. and S. hygrospinosus var. kunmingensis Yan et al.. However, it was significant differences from the above organisms in the following aspects, the color of spore mass and substrate mycelium, the utilization of carbon sources and the production of antibiotics. As a result of the above mentioned characteristics, it is named Streptomyces hygrospinosus subsp. guilinesis n. subsp..
