title: [Comparison of the efficiency of 2 culture media in the recovery of heterotrophic bacteria damaged with chlorine].
abstract: In this study, culture mediums R2A and m-HPC were compared with respect to their efficiency in the recuperation of injured heterotrophic bacteria present in water, which previously was treated with chlorine. The results of total counts obtained by membrane filtration, show that medium R2A was better than m-HPC. These two culture mediums are indicated by the 16th edition of Standard Methods for the Examination of Water and Waste-water. The results obtained may be due to the low concentration of organic matter, or to the presence of yeast extract in the R2A medium.
