主 题:cultivation growth factors heme sandwich agar plate uncultured bacteria
摘 要:In the classical microbial isolation technique,the isolation process inevitably destroys all microbial interactions and thus makes it difficult to culture the many microorganisms that rely on these interactions for *** this study,we designed a simple coculture technique named the“sandwich agar plate method,which maintains microbial interactions throughout the isolation and pure culture *** total yield of uncultured species in sandwich agar plates based on eight helper strains was almost 10-fold that of the control *** uncultured species displayed commensal *** study found that heme was the growth-promoting factor of some marine commensal *** genomic analysis revealed that heme auxotrophies were common in various biotopes and prevalent in many uncultured microbial ***,our study supported that the survival strategies of heme auxotrophy in different habitats varied *** findings highlight that cocultivation based on the“sandwich agar plate methodcould be developed and used to isolate more uncultured bacteria.
