Abstract A set of 110 extremely halophilic archaeal strains were isolated from seven distinct saline habitats located in different regions Algeria. The physicochemical characterization the samples showed that these thalassohaline. carotenoid production varied 0.1 to 3.68 µg/ml. Based on their physiological characteristics and pigment production, 43 selected identified by means phenotypic tests 16S ribosomal RNA gene sequencing. Phylogenetic analysis indicated isolates corresponded class...
The genus Geobacillus is comprised of a diverse group spore-forming Gram-positive thermophilic bacterial species and well known for both its ecological diversity as source novel thermostable enzymes. Although the mechanisms underlying thermophilicity organism thermostability macromolecules are reasonably understood, relatively little evolutionary mechanisms, which underlie structural functional properties members this genus. In study, we have compared 29 genomes, with specific focus on...
Proteases have numerous biotechnological applications and the bioprospection for newly-thermostable proteases from great biodiversity of thermophilic microorganisms inhabiting hot environments, such as geothermal sources, aims to discover more effective enzymes processes at higher temperatures. We report in this paper production characterization a purified acid protease strain OA30, moderate bacterium isolated an Algerian spring. Phenotypic genotypic study OA30 was followed by extracellular...
Algeria has numerous natural hypersaline environments (sabkha and chott) located in the north south of country. In course screening microorganisms form these environments, we isolated characterized 44 haloarchaeal strains. According to their phenotypic characteristics comparative 16S rRNA sequence analysis, all isolates belonged family Halobacteriaceae including members related species genera Halorubrum, Haloterrigena, Halogeometricum, Halobacterium, Haloferax, Halomicrobium Haloarcula. Our...
ABSTRACT Geobacillus spp. are potential sources of novel enzymes, such as those involved in the degradation recalcitrant polymers. Here, we report a genome that may help reveal genomic differences between this strain and publicly available representatives same genus from diverse niches.
Abstract The members of the genus Thermoactinomyces are known for their protein degradative capacities. sp. strain AS95 is a Gram-positive filamentous bacterium, isolated from moderately saline water in Thamelaht region Algeria. This isolate thermophilic aerobic bacterium with capacity to produce extracellular proteolytic enzymes. exhibits up 99 % similarity Thermoactinomyces, based on 16S rRNA gene sequence similarity. Here we report phenotypic features together draft genome and its...
Natural hot environments can represent an important source of microbial biodiversity and biomole¬cules with great added value. In this work, we compare the diversity prokaryotic communities in Debagh Ouled Ali, two terrestrial springs located province Guelma (Algeria) using high-through¬put sequencing methods. Environmental DNA was extracted from 23 sediment samples collected 4 sampling sites these springs. Sequences V4 hypervariable region environmental 16S rRNA gene were obtained by MiSeq...
