1. Halotolerant bacteria in the São Paulo Zoo composting process and their hydrolases and bioproducts
Halophilic microorganisms are able to grow in the presence of salt and are also excellent source of enzymes and biotechnological products, such as exopolysaccharides (EPSs) and polyhydroxyalkanoates (PHAs). Salt-tolerant bacteria were screened in the Organic Composting Production Unit (OCPU) of São Paulo Zoological Park Foundation, which processes 4 ton/day

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. Extracellular proteases of Halobacillus blutaparonensis strain M9, a new moderately halophilic bacterium
Halophilic microorganisms are source of potential hydrolytic enzymes to be used in industrial and/or biotechnological processes. In the present study, we have investigated the ability of the moderately halophilic bacterium Halobacillus blutaparonensis (strain M9), a novel species described by our group, to release proteolytic enzymes. This bacterial strain a

4. Taxonomic study and partial characterization of antimicrobial compounds from a moderately halophilic strain of the genus Actinoalloteichus
A moderately halophilic actinomycete strain designated AH97 was isolated from a saline Saharan soil, and selected for its antimicrobial activities against bacteria and fungi. The AH97 strain was identified by morphological, chemotaxonomic and phylogenetic analyses to the genus Actinoalloteichus. Analysis of the 16S rDNA sequence of strain AH97 showed a simil

5. Influência dos nutrientes nitrogênio e fósforo na degradação anaeróbia do pentaclorofenol e na diversidade microbiana dos sedimentos enriquecidos do Estuário de Santos-São Vicente, Estado de São Paulo / Influence of nitrogen and phosphorus nutrients on the anaerobic degradation of pentachlorophenol and on the natural microbial diversity of sediments from the Santos-São Vicente estuary, state of São Paulo, Brazil
The research presented here aimed to determine the optimal nutritional conditions for the use of sediment from the Santos-São Vicente estuary in the state of São Paulo, Brazil, as an inoculum for a horizontal-flow anaerobic immobilized biomass reactor (HAIB) applied to the anaerobic degradation of pentachlorophenol (PCP), seeking to apply the technology on

6. Isolamento e caracterização de haloarqueas cultivadas em compostos aromaticos e construção de ferramentas moleculares para o estudo da secreção proteica no Dominio Archaea / Isolation and characterization of haloarqueas grown in aromatics and construction of molecular tools to study the protein secretion in the Domain Archaea
O metabolismo de compostos aromáticos depende de fatores físico-químicos como temperatura, pH e salinidade, e é bem conhecido e caracterizado em microrganismos mesófilos e em condições ambientais moderadas. No entanto, pouco se conhece sobre o metabolismo desses compostos em ambientes hipersalinos. este trabalho, cinco ambientes hipersalinos foram ana

8. Biology of Moderately Halophilic Aerobic Bacteria
The moderately halophilic heterotrophic aerobic bacteria form a diverse group of microorganisms. The property of halophilism is widespread within the bacterial domain. Bacterial halophiles are abundant in environments such as salt lakes, saline soils, and salted food products. Most species keep their intracellular ionic concentrations at low levels while syn

9. Bioenergetic Aspects of Halophilism
Examinination of microbial diversity in environments of increasing salt concentrations indicates that certain types of dissimilatory metabolism do not occur at the highest salinities. Examples are methanogenesis for H2 + CO2 or from acetate, dissimilatory sulfate reduction with oxidation of acetate, and autotrophic nitrification. Occurrence of the different

10. Genome sequence of Haloarcula marismortui: A halophilic archaeon from the Dead Sea
We report the complete sequence of the 4,274,642-bp genome of Haloarcula marismortui, a halophilic archaeal isolate from the Dead Sea. The genome is organized into nine circular replicons of varying G+C compositions ranging from 54% to 62%. Comparison of the genome architectures of Halobacterium sp. NRC-1 and H. marismortui suggests a common ancestor for the

11. Accumulation of Poly (β-Hydroxybutyrate) by Halobacteria
Some species of extremely halophilic archaebacteria, Halobacteriaceae, have been shown to accumulate large amounts of poly (β-hydroxybutyrate) under conditions of nitrogen limitation and abundant carbon source. The production of poly (β-hydroxybutyrate), at least in large quantities, was restricted to two carbohydrate-utilizing species, Halobacterium medit

12. Ectoine from halophilic microorganisms induces the expression of hsp70 and hsp70B′ in human keratinocytes modulating the proinflammatory response
The heat shock proteins (Hsps) have an important role in the cytoprotection and repair of cells and tissues. One potential mechanism of protection is the ability of Hsp to inhibit genetic expression of proinflammatory cytokines, the transcription of which is dependent on nuclear factor–kappa B (NF-κB) activation. In this study, we evaluated the ability of
