1. Isolamento de enterococos e coliformes fecais de ostras (Crassostrea rhizophorae) comercializadas na praia do futuro, Fortaleza, CearÃ. / Isolation of enterococos and fecais coliformes of oysters (Crassostrea rhizophorae) sold in the beach of the Futuro, Fortaleza, CearÃ.
Foram estimados o NÃmero Mais ProvÃvel (NMP) de enterococos e de coliformes termotolerantes de 60 amostras de ostras (Crassostrea rhizophorae) comercializadas em duas barracas: A e B, na Praia do Futuro em Fortaleza â CE, no perÃodo de setembro de 2000 a setembro de 2001. Cada amostra constava de 25 indivÃduos, totalizando assim a anÃlise de aproximada

2. Microbiology Study of a Hypersaline Lake in French Somaliland
In a study of a lake having a higher concentration of salts than the Dead Sea, all of the heterotrophic bacteria isolated were aerobes; no strictly anaerobic strains were found. Ninety percent of the strains were euryhalines and ten percent were strict halophiles. The extreme halophiles belonged to the species Halobacterium trapanicum and Halococcus morrhuae

3. Thermal Inactivation of a Deep-Sea Barophilic Bacterium, Isolate CNPT-3
The barophilic deep-sea bacterium, isolate CNPT-3, was inactivated by exposures to temperatures between 10 and 32°C at atmospheric pressure. Inactivation in samples from warmed cell suspensions was measured as the loss of colonyforming ability (CFA) at 10°C and 587 bars. At atmospheric pressure, there was a slow loss of CFA even at 10°C. The loss of CFA w

4. Obligately barophilic bacterium from the Mariana trench.
An amphipod (Hirondellea gigas) was retrieved with decompression in an insulated trap from an ocean depth of 10,476 m. Bacterial isolates were obtained from the dead and cold animal by using silica gel medium incubated at 1000 bars (1 bar = 10(5) Pa) and 2 degrees C. The isolate designated MT41 was found to be obligately barophilic and did not grow at a pres

5. Search and Discovery Strategies for Biotechnology: the Paradigm Shift
Profound changes are occurring in the strategies that biotechnology-based industries are deploying in the search for exploitable biology and to discover new products and develop new or improved processes. The advances that have been made in the past decade in areas such as combinatorial chemistry, combinatorial biosynthesis, metabolic pathway engineering, ge

6. Amplification of a 500-Base-Pair Fragment from Cultured Isolates of Mycobacterium bovis
The presence of a 500-bp fragment which amplifies a region from the genome of Mycobacterium bovis (J. G. Rodriguez, G. A. Meija, P. Del Portillo, M. E. Patarroyo, and L. A. Murillo, Microbiology 141:2131–2138, 1995) was evaluated by carrying out PCR on 121 M. bovis isolates. The M. bovis strains, previously characterized by culture and biochemical tests, w

7. Phylogenetic analysis of a natural marine bacterioplankton population by rRNA gene cloning and sequencing.
The identification of the prokaryotic species which constitute marine bacterioplankton communities has been a long-standing problem in marine microbiology. To address this question, we used the polymerase chain reaction to construct and analyze a library of 51 small-subunit (16S) rRNA genes cloned from Sargasso Sea bacterioplankton genomic DNA.
