WebNov 1, 2006 · Introduction. Streptococcus oligofermentans is a newly characterized species belonging to the mitis group of oral streptococci (Tong et al., 2003).It was initially isolated from the dental plaques of carious-free humans in China. Epidemiological studies have not found any correlation between S. oligofermentans and dental caries, suggesting that this …
WebS. oligofermentans as responsible for this biological activity. Consequently, the lox mutant of S. oligofermentansalso showed dramatically reduced inhibitory effects against S. mutans and also exhib-ited greatly impaired growth in the presence of the lactate produced by S. mutans. These data indicate that S. oligofermentans possesses the ... WebSeveral growth conditions were examined in the model, namely: S. oligofermentans was inoculated 24 h before S. mutans or vice versa; the growth medium was supplemented with 0.2% sucrose or 0.4% glucose; biofilms were grown under a constantly neutral pH or pH-cycling condition, which included 8 h of neutral pH and 16 h of pH 5.5.
