Abstract:
ABSTRACTEnvironmental gradients are expected to promote the diversification and coexistence of ecological specialists adapted to local conditions. Consistent with this view, genera of phototrophic microorganisms in alkaline geothermal systems generally appear to consist of anciently divergent populations which have specialized on different temperature habitats. At White Creek (Lower Geyser Basin, Yellowstone National Park), however, a novel, 16S rRNA-defined lineage of the filamentous anoxygenic phototrophChloroflexus(OTU 10, phylumChloroflexi) occupies a much wider thermal niche than other 16

Abstract:
Improving the strength and stability of cement-based structures in adverse environmental conditions with associated anthropogenic influences is possible through the development and implementation of nature-like and nature-friendly technologies. The ability of urobacteria to precipitate calcium carbonate can be useful in the manufacture of self-healing and reinforced concrete, in the crack healing and the restoration of concrete structures. Hypersaline environment is an ecological niche for search for microorganisms that are resistant to increased alkalinity, changing environmental conditions a

Abstract:
The rapid emergence of bacterial resistance to antibiotics has urged the need to find novel bioactive compounds against resistant microorganisms. For that purpose, different strategies are being followed, one of them being exploring secondary metabolite production in microorganisms from uncommon sources. In this work, we have analyzed the genome of 12 Streptomyces sp. strains of the CS collection isolated from the surface of leaf-cutting ants of the Attini tribe and compared them to four Streptomyces model species and Pseudonocardia sp.

Abstract:
To investigate the diversity of industrially useful microorganisms from fermented agricultural products in the Sacheon region, 128 strains were isolated and analyzed phylogenetically. The analysis indicated that the isolates were categorized into three phyla, eight families, 13 genera, and 33 species. The Bacillaceae family, which was the main taxon, comprised 88.3% of the isolates and included four genera and 22 species: Bacillus, Exiguobacterium, Fictibacillus, and Metabacillus. The Caryophanaceae family, which was the second most abundant taxon, comprised 3.9% of the isolates, including two

Abstract:
Endolichenic microorganisms represent a new source of bioactive natural compounds. Lichens, resulting from a symbiotic association between algae or cyanobacteria and fungi, constitute an original ecological niche for these microorganisms. Endolichenic fungi inhabiting inside the lichen thallus have been isolated and characterized. By cultivation on three different culture media, endolichenic fungi gave rise to a wide diversity of bioactive metabolites. A total of 38 extracts were screened for their anti-maturation effect on Candida albicans biofilms. The 10 most active ones, inducing at least

Abstract:
The market for probiotic foods has grown significantly in recent years. Some microorganisms isolated from food fermentations, mainly lactic acid bacteria (LAB) and yeasts, may have probiotic potential. During the fermentation of cocoa and coffee, a plethora of microorganisms are involved, including yeasts and lactic acid bacteria (LAB), several of which may have probiotic potential. For this reason, this study aimed to overview the probiotic potential of some LAB and yeasts isolated from these fermentation processes. For this purpose, a search was conducted in several specialized databases (Go

Abstract:
In previous research, volatile organic compounds (VOCs) emitted by various bacteria into the chemosphere were suggested to play a significant role in the antagonistic interactions between microorganisms occupying the same ecological niche and between bacteria and target eukaryotes. Moreover, a number of volatiles released by bacteria were reported to suppress quorum-sensing cell-to-cell communication in bacteria, and to stimulate plant growth. Here, volatiles produced byPseudomonasandSerratiastrains isolated mainly from the soil or rhizosphere exhibited bacteriostatic action on phytopathogenic

Abstract:
Spore formers are ubiquitous microorganisms commonly isolated from most environments, including the gastro-intestinal tract (GIT) of insects and animals. Spores ingested as food and water contaminants safely transit the stomach and reach the intestine, where some of them germinate and temporarily colonize that niche. In the lower part of the GIT, they re-sporulate and leave the body as spores, therefore passing through their entire life cycle in the animal body. In the intestine, both un-germinated spores and germination-derived cells interact with intestinal and immune cells and have health-b

On the Israeli side it was shown that higher medicarpin levels are exuded following the application of Rhizobium meliloti to the rhizosphere but the specific biochemical pathway governing medicarpin pro
