25. Atividade antibacteriana de culturas láticas isoladas de salame tipo italiano
Bactérias láticas foram isoladas durante o processamento de salame tipo italiano, obtido a partir de duas plantas de processamento, no Estado do Paraná. Para o isolamento, foram utilizados os meios MRS, D-MRS e M17. Um total de 484 isolados teve sua atividade antibacteriana testada sobre Listeria monocytogenes (Laboratório de Microbiologia - UFV), Staphy

26. Produção e caracterização de hidrolisado pancreatico de isolado proteico de soja para nutrição clinica
This work dealt with the pancreatic hydrolysis of soy protein isolates (SPI) for the production of a low molecular weight hydrolysis, as well as the biochemical and nutritional characterization of the product. The selected process was a discontinuous one at 37° C in deionized water and without pH adjustment in order to minimize concentration of inorganic io

27. A Method of Profiling Microbial Communities Based on a Most-Probable-Number Assay That Uses BIOLOG Plates and Multiple Sole Carbon Sources
A new approach to the community-level BIOLOG assay was proposed. This assay, which we call the BIOLOG-MPN assay, is a most-probable-number (MPN) assay that uses BIOLOG plates and multiple sole carbon sources, and the profiles obtained by this assay consist of MPNs estimated for the substrates in the BIOLOG plates. In order to demonstrate the performance of t

28. Application of Carbon Source Utilization Patterns To Measure the Metabolic Similarity of Complex Dental Plaque Biofilm Microcosms
Biolog technology was applied to measure the metabolic similarity of plaque biofilm microcosms, which model the complex properties of dental plaque in vivo. The choice of Biolog plate, incubation time, and incubation conditions strongly influenced utilization profiles. For plaque biofilm microcosms, Biolog GP2 plates incubated anaerobically in an H2-free atm

29. BIOLOG - a DNA sequence analysis system in PROLOG.
BIOLOG contains facilities for the analysis of nucleic acid sequences. These facilities are available through queries and commands of the underlying implementation language PROLOG. Familiarity with PROLOG is gained by using the built-in BIOLOG functions. This experience should enable the user to extend the current system and define new facilities.

30. Analysis of BIOLOG GN Substrate Utilization Patterns by Microbial Communities
BIOLOG GN plates are increasingly used to characterize microbial communities by determining the ability of the communities to oxidize various carbon sources. Studies were done to determine whether the BIOLOG GN plate assay accurately reflects the catabolic potential of the inoculum used. To gain insight into which populations of microbial communities contrib

31. Preliminary evaluation of Biolog, a carbon source utilization method for bacterial identification.
The Biolog Identification System (Biolog, Inc., Hayward, Calif.) is a new bacterial identification method that establishes an identification based on the exchange of electrons generated during respiration, leading to a subsequent tetrazolium-based color change. This system tests the ability of a microorganism to oxidize a panel of 95 different carbon sources

32. Evaluation of Biolog for identification of members of the family Micrococcaceae.
The Biolog Identification System (Biolog, Inc., Hayward, Calif.) was challenged at two separate laboratories with 113 coded isolates, including 33 type strains of staphylococci, 5 strains of Micrococcus spp., and 1 strain of Stomatococcus mucilaginosus. Test parameters between the sites were controlled as much as possible. Discrepancies were arbitrated by us

33. Evaluation of Biolog system for identification of some gram-negative bacteria of clinical importance.
The Biolog system (Biolog, Inc., Hayward, Calif.) was evaluated for the identification of 55 gram-negative taxa (789 strains) likely to be encountered commonly in clinical laboratories. The Biolog system performed best with oxidase-positive fermenters and biochemically active nonfermenters and had the most problems with unreactive nonfermenters. It gave sign

34. Phenotypic and genotypic characterization of phenanthrene-degrading fluorescent Pseudomonas biovars.
A total of 41 phenanthrene degraders were isolated from a former coal gasification site by using Pseudomonas-selective Gould's S1 medium. All isolates were found to belong to the fluorescent Pseudomonas group and were subjected to characterization by phenotypic methods, including classical taxonomic tests, API 20NE, and Biolog GN, and the strains were furthe

35. Evaluation of the Biolog automated microbial identification system.
Biolog's identification system was used to identify 39 American Type Culture Collection reference taxa and 45 gram-negative isolates from water samples. Of the reference strains, 98% were identified to genus level and 76% to species level within 4 to 24 h. Identification of some authentic strains of Enterobacter, Klebsiella, and Serratia was unreliable. A to

36. Biochemical and Molecular Characterization of Obesumbacterium proteus, a Common Contaminant of Brewing Yeasts
We have evaluated the effectiveness of API 20E, Biolog testing, plasmid profiling, ribotyping, and enteric repetitive intergenic consensus (ERIC)-PCR to characterize, classify, and differentiate nine bacterial isolates of the common brewery contaminant Obesumbacterium proteus. Of the five typing techniques, Biolog testing, plasmid profiling, and ERIC-PCR pro
