A new medium for the differentiation of B. coli in water analysis

ABSTRACT

B. coli (lactose +, indol +) may be isolated by the standard method not only from faeces and polluted waters, but also from unpolluted soils and unpolluted waters. As a standard indicator of faecal contamination its value is therefore unquestionable. Local experience indicates that the utilisation of citrate by B. coli may be of value in differentiating faecal from non-faecal B. coli in water analysis (Summary)
