Microbial diversity in soils suppressive to diseases.

species are cosmopolitan soil phytopathogens from the division , which produce mycotoxins and cause significant economic losses of crop plants. However, soils suppressive to diseases are known to occur, and recent knowledge on microbial diversity in these soils has shed new lights on phytoprotection effects. In this review, we synthesize current knowledge on soils suppressive to diseases and the role of their rhizosphere microbiota in phytoprotection.

Two novel species isolated from wheat rhizospheres in Serbia: Pseudomonas serbica sp. nov. and Pseudomonas serboccidentalis sp. nov.

Pseudomonas strains IT-194P, IT-215P, IT-P366 and IT-P374 were isolated from the rhizospheres of wheat grown in soils sampled from different fields (some of them known to be disease-suppressive) located near Mionica, Serbia. Phylogenetic analysis of the 16S rRNA genes and of whole genome sequences showed that these strains belong to two potentially new species, one containing strains IT-P366 and IT-194P and clustering (whole genome analysis) next to P. umsongensis DSM16611, and another species containing strains IT-P374 and IT-215P and clustering next to P.

Endorhizosphere of indigenous succulent halophytes: a valuable resource of plant growth promoting bacteria.

The adaptability of halophytes to increased soil salinity is related to complex rhizosphere interactions. In this study, an integrative approach, combining culture-independent and culture-dependent techniques was used to analyze the bacterial communities in the endorizosphere of indigenous succulent halophytes Salicornia europaea, Suaeda maritima, and Camphorosma annua from the natural salt marshes of Slano Kopovo (Serbia). The 16 S rDNA analyses gave, for the first time, an insight into the composition of the endophytic bacterial communities of S.

Biomagnetic Priming-Possible Strategy to Revitalize Old Mustard Seeds.

Different priming methods were developed to improve seed germination and the early growth of seedlings. This study aimed to examine the combined effect of bacterial inoculation and static magnetic field on white mustard (Sinapis alba L.) germination.

Listeria monocytogenes - Danger for health safety vegetable production.

The microbiologically contaminated vegetables represent a risk for consumers, especially vegetables without thermal processing. It is known that human pathogen bacteria, such as Listeria monocytogenes, could exist on fresh vegetables. The fresh vegetables could become Listeria-contaminated if they come in touch with contaminated soil, manure, irrigation water.

Copper-tolerant yeasts: Raman spectroscopy in determination of bioaccumulation mechanism.

Modern, efficient, and cost-effective approach to remediation of heavy metal-contaminated soil is based on the application of microorganisms. In this paper, four isolates from agricultural and urban contaminated soil showed abundant growth in the presence of copper(II) sulfate pentahydrate (CuSO·5HO) up to 2 mM. Selected yeasts were identified by molecular methods as Candida tropicalis (three isolates) and Schwanniomyces occidentalis (one isolate).
