Abstract |
Various enteric organisms were exposed to axenic cultures of green and blue-green algae to determine what effect the algae might have. Tests were extended to 90 days to determine whether aftergrowth was possible. Mixed cultures of both green and blue-green algae were exposed to both single species and mixed cultures of enteric bacteria, at varying stages of the algae growth periods. Results indicated that mixed cultures do have a pronounced bactericidal effect on enteric organisms, while for single alga species, the effect is less pronounced. Also, the bactericidal effects are more specific for pathogens, with virtually no aftergrowth of pathogens detected. (WRSIC abstract) |
