Lactobacillus acidipiscis sp. nov. and Weissella thailandensis sp. nov., isolated from fermented fish in Thailand

S Tanasupawat, O Shida, S Okada and K Komagata Department of Microbiology, Faculty of Pharmaceutical Sciences, Chulalongkorn University, Bangkok 10330, Thailand Eleven strains of homofermentative, rod-shaped lactic acid bacteria and five strains of heterofermentative, sphere-shaped lactic acid bacteria were isolated from fermented fish (pla-ra and pla-chom) in Thailand. They were identified as new species and named Lactobacillus acidipiscis sp. nov. and Weissella thailandensis sp. nov., respectively, on the basis of phylogenetic analysis of the 16S rRNA gene sequences, DNA relatedness and phenotypic characteristics. The type strain of L. acidipiscis is FS60-1(T) (=PCU 207(T)=NRIC 0300(T)=HSCC 1411(T)=JCM 10692(T)=TISTR 1386(T)) and the type strain of Weissella thailandensis is FS61-1(T) (=PCU 210(T)=NRIC 0298(T)=HSCC 1412(T)=JCM 10695(T)=TISTR 1384(T)).
