The presence of EPS produced by bacterial cells contributes to slime colonies formation in solid medium and increased viscosity in liquid medium. This paper proposes an alternative method for screening EPS-producing lactic acid bacteria using solid medium-containing discs of filter paper that are saturated with active cultures. The screening was carried out under different culture conditions varying the type of sugar, pH, and temperature. EPS production was visualized by the presence of mucoid colonies on the discs, which was confirmed by the formation of a precipitate when part of this colony was mixed with absolute alcohol. The established conditions for obtaining a high number of isolates producing EPS were 10% sucrose, pH 7.5 and 28 ºC. This method proved to be effective and economical because several strains could be tested on the same plate, with immediate confirmation.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-04-29T14:00:51Z No. of bitstreams: 1 Milton Ricardo de Abreu Roque.pdf: 3240469 bytes, checksum: e0aece3686bd76f91c3d9159dd78b6fb (MD5)Approved for entry into archive by Patricia Barroso (pbarroso@ufba.br) on 2014-05-01T13:00:09Z (GMT) No. of bitstreams: 1 Milton Ricardo de Abreu Roque.pdf: 3240469 bytes, checksum: e0aece3686bd76f91c3d9159dd78b6fb (MD5)Made available in DSpace on 2014-05-01T13:00:09Z (GMT).
