VILLEGAS BLANCO, Maikel Fausto. Assessment of Agar Blue Bromotimol Lactose introduced in BioCen using reference strans. Rev Cubana Invest Bioméd [online]. 2009, vol.28, n.1, pp. 0-0. ISSN 1561-3011.

OBJECTIVE: to show results obtained in evaluations performed in agar blue bromotimol lactose culture media produced in BioCen, Cuba, and that marketed by Merck, Germany, created for microorganism differentiation, specially the Enterobacter ones, due to its ability for lactose fermentation. METHODS: we assayed a total of 13 certified strains and another isolated from water sample, from Research Department of Culture Media (BeioCen). RESULTS: values or Growing Relative Index for 10 strains were above 90 %, with 71,5% of total, while that only 4 strains shoed lower values to a 28,5 % of total. All strains exceeded the recommended value (>70%). CONCLUSIONS: strains evaluated in both products showed similarity as regard its response and to morphologic features of colonies.
