background and objectives: the usepa has suggested faecal enterococci as the primary bacterial indicators. of more importance is their direct correlation with swimmer-associated gastroenteritis in recreation water quality monitoring. in contrast to other seawater bodies with 3.5% salinity, the recreational waters in the southern coast of the caspian sea possess its own salinity (about 1% w/v) a...

Inactivation of E. coli and Klebsiella pneumoniae by addition H2O2 10 mg L?1 into natural well water samples containing total iron concentrations (around 0.3 L?1) under simulated solar light was followed bacterial culturability (plate count) viability (DVC-FISH). Results showed that both bacteria totally reduced while only completely depleted for in depending concentration. Post-irradiation eff...

The marine toxic dinoflagellate Ostreopsis lenticularis Fukuyo 1981 is implicated as the major vector in ciguatera fish poisoning in the southwest coast of Puerto Rico. Studies have demonstrated that bacteria play a role in the production of ciguatoxin by the dinoflagellate and that different clonal cultures of Ostreopsis harbor different culturable bacterial symbionts. It was recently demonstr...

An environmental isolate of Salmonella Enteritidis (SE), grown to the logarithmic phase, rapidly lost culturability by the addition of 3 mM H2O2 to cultures grown in Luria-Bertani (LB) medium; however, some H2O2-treated bacteria regained their culturability in M9 minimal medium, if sodium pyruvate was present at at least 0.3 mM. In addition, most pyruvate analogues, such as bromopyruvate or phe...
