1. Diversity of retrievable heterotrophic bacteria in Kongsfjorden, an Arctic fjord
Abstract The diversity and abundance of retrievable pelagic heterotrophic bacteria in Kongsfjorden, an Arctic fjord, was studied during the summer of 2011 (June, August, and September). Retrievable bacterial load ranged from 103 to 107 CFU L−1 in June, while it was 104-106 CFU L−1 in August and September. Based on 16S rRNA gene sequence similarities, a h

2. Culturable diversity of halophilic bacteria in foreshore soils
Halophilic bacteria are commonly found in natural environments containing significant concentration of NaCl such as inland salt lakes and evaporated sea-shore pools, as well as environments such as curing brines, salted food products and saline soils. Dependence on salt is an important phenotypic characteristic of halophilic bacteria, which can be used in th

3. Monitoramento temporal e espacial de contaminações bacterianas na produção de bioetanol: caracterização molecular por T-RFLP e detecção quantitativa por qPCRde comunidades formadoras de biofilmes / Temporal and spatial monitoring of bacterial contamination in bioethanol production: a molecular characterization by T-RFLP and quantitative detection by qPCR of community-formers biofilms
Bacterial contamination by Lactobacillus, Bacillus and Leuconostoc and other lactic acid bacteria is one of the main factors that affects the yield in alcoholic fermentation process. Biofilm formation protects the bacteria community and it is a permanent source of contamination. For characterization of these contaminations in (1) biofilms from centrifuge, ta

4. Screening and isolation of halophilic bacteria producing industrially important enzymes
Halophiles are excellent sources of enzymes that are not only salt stable but also can withstand and carry out reactions efficiently under extreme conditions. The aim of the study was to isolate and study the diversity among halophilic bacteria producing enzymes of industrial value. Screening of halophiles from various saline habitats of India led to isolati

5. Bacterial exopolysaccharide and biofilm formation stimulate chickpea growth and soil aggregation under salt stress
To compensate for stress imposed by salinity, biofilm formation and exopolysaccharide production are significant strategies of salt tolerant bacteria to assist metabolism. We hypothesized that two previously isolated salt-tolerant strains Halomonas variabilis (HT1) and Planococcus rifietoensis (RT4) have an ability to improve plant growth, These strains can

6. Caracterização da comunidade microbiana em ambientes salinos e suas possíveis aplicações biotecnológicas / Caracterization of the microbiol community in saline environments and their possible biotechnological applications
A água residuária da extração de petróleo é altamente salina e contém uma mistura complexa de hidrocarbonetos, muitos dos quais são altamente tóxicos. Com o aumento da preocupação em preservar o meio ambiente, as tecnologias voltadas para a recuperação e despoluição de áreas degradadas tem ganhado a atenção. A biorremediação tem sido util

7. Degradação de compostos aromaticos por microormanismos haloficos e aplicação destes na biorremediação da agua de petroleo / Degradation of aromatic compounds microoganism and their application in bioremediation of water production oil
Os microrganismos halofilicos sao aqueles capazes de viver em ambientes salinos. Dentre eles encontram-se, por exemplo, as bacterias halofilicas e as haloarqueias. Estas duas classes de organismos foram o objeto de estudo deste projeto. Estes microrganismos foram testados quanto a habilidade de degradacao de compostos monoaromaticos e poliaromaticos. A capac

8. Enzymatic and biodegrader activities of petroleum microorganisms from Campos Basin (Pampo Sul) / Atividades enzimaticas e de biodegração de microorganismos do petroleo da Bacia de Campos (Pampo Sul)
Amostras de águas de formação de petróleo e óleos foram coletadas na Formação Pampo, situada na Bacia de Campos, através das quais, aplicando-se diferentes condições de cultivo, foram recuperadas 92 linhagens de bactérias aeróbias. Dentre os isolados, obtidos, 29 foram identificados por técnicas moleculares baseadas em DNAr 16S, observando-se a

10. Synchronous Effects of Temperature, Hydrostatic Pressure, and Salinity on Growth, Phospholipid Profiles, and Protein Patterns of Four Halomonas Species Isolated from Deep-Sea Hydrothermal- Vent and Sea Surface Environments
Four strains of euryhaline bacteria belonging to the genus Halomonas were tested for their response to a range of temperatures (2, 13, and 30°C), hydrostatic pressures (0.1, 7.5, 15, 25, 35, 45, and 55 MPa), and salinities (4, 11, and 17% total salts). The isolates were psychrotolerant, halophilic to moderately halophilic, and piezotolerant, growing fastest

11. Functional Expression of the Ectoine Hydroxylase Gene (thpD) from Streptomyces chrysomallus in Halomonas elongata
The formation of hydroxyectoine in the industrial ectoine producer Halomonas elongata was improved by the heterologous expression of the ectoine hydroxylase gene, thpD, from Streptomyces chrysomallus. The efficient conversion of ectoine to hydroxyectoine was achieved by the concerted regulation of thpD by the H. elongata ectA promoter.

12. Development of a gene reporter system in moderately halophilic bacteria by employing the ice nucleation gene of Pseudomonas syringae.
The expression of the ice nucleation gene inaZ of Pseudomonas syringae in several moderate halophiles was investigated to establish its utility as a reporter for promoter activity and gene expression studies in these biotechnologically and environmentally important bacteria. A promoterless version of inaZ was introduced in two different restriction sites and
