Some Observations on the Viability of Sewage Bacteria in Relation to Self‐purification of Mussels

Abstract

SUMMARY: Autoclaved sea water and water removed from the shell cavity of mussels supported the growth of coli‐aerogenes bacteria. Attempts to reproduce conditions which had favored multiplication of coli‐aerogenes bacteria in purified mussels failed. ‘Enrichment’ of sea water by repeated re‐use for storage of successive lots of mussels, in conjunction with sand filtration and aeration under conditions equivalent to 60 weeks of approved purification, did not promote the growth of coli‐aerogenes bacteria. A culture of Salmonella typhi and Salm. paratyphi B survived for a few days only in sea water favourable to the slow multiplication of Bacterium coli type I.

Factors Affecting the Survival of Bacteria in Sea Water1

“…It was concluded that the rapid death of bacteria in sea water was due to some extent to an autochthonous microflora of antibiotic-producing organisms. Ketchum et al (1949) observed that a second inoculum of E. coli in sea water died more rapidly than the first, and Sherwood (1952) found that sea water which had supported growth of E. coli did not favor prolonged survival of Salmonella typhosa or S. paratyphi. These results were interpreted in terms of microbial antagonism and the production of antibiotic substances.…”
