the impact of phenolic-contaminated water on microbial community structure was assessed using biolog microarrays techniques. the following biolog plates were used: gen iii plates, new test panel for identification of both gram-negative and gram-positive bacteria, ecoplates microarray for evaluation of functional diversity of microbial communities and phenotype microarrays (pms) for characteriza...

Nine strains of Erwinia amylovora were isolated from new host plants in Bulgaria--chokeberry and strawberry. The strains were characterized morphologically and biochemically using the API 20E and BIOLOG system. It was established that they showed three different API 20E metabolic profiles, not found by previous studies of E. amylovora. All strains were identified as E. amylovora due to their me...

One hundred and fifty-nine isolates representing 16 genera and 53 species of yeasts were processed with the Biolog MicroStation System for yeast identification. Thirteen genera and 38 species were included in the Biolog database. For these 129 isolates, correct identifications to the species level were 13.2, 39.5 and 48.8% after 24, 48 and 72 hours incubation at 30 degrees C, respectively. Thre...

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. We report on a preliminary investig...

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 atmosphere gave the clearest profile. To...

Bacteria of the Rhizobium genus form a group microorganisms existing in environment two forms: symbiotic, root nodules Fabaceae sp. plants and free-living, saprophytic soil environment. The subject this study was genetic identification characterization metabolic activity different strains from bacteria. conducted on 16 bacteria collection Department Agricultural Microbiology, Institute Soil Sci...

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 significantly better results when the Mic...
