Abstract:
This study investigated the bacterial communities in a spring barley monoculture site subjected to two different input regimes for over 12 years: a conventional chemical/fertiliser regime, and a reduced input regime. A culture independent approach was performed to compare the bacterial communities through 16S rRNA gene PCR-DGGE. PCO analysis revealed that the rhizosphere has a strong structuring effect on the bacterial community. Moreover, high inputs of agrichemicals lead to an increase of phosphorus level in the soil and a concomitant reduction of the bacterial diversity. These results may h

Abstract:
Chemical precipitation in combination with biological treatment is a commonly used method for removal of turbidity and dissolved organic carbon (DOC) from drinking water. DOC is largely removed during biological treatment, which includes ozonation and filtration through a biologically active carbon (BAC) filter. Ozone converts humic substances into a biologically labile form that is mineralised by bacteria living in the following BAC filter. This study shows that this approach is often not efficient for removal of DOC from waters with a high amount of humic substances. During chemical treatmen

Ammonium sulphate and an ammonium sulphate-ammonium phosphate mixture were applied at 200 kg N ha-1 and 200 kg P ha-1 at three clearcut sites within the Interior Cedar-Hemlock biogeoclimatic zone in southern British Columbia. N mineralised under aerobic and anaerobic conditions, nitrification, biomasses of fungi and bacteria,the abundance of protozoa, and the trophic structure of nematode communities were studied at 4, 12, 16, and 28 mo after fertilisation. Nitrogen mineralised under aerobic conditions was greater in fertilised soil than in non-fertilised soil at 4 and 16 mo after fertiliser a

Abstract:
Background: Exposure of seeds to high salinity can cause reduced germination and poor seedling establishment. Improving the salt tolerance of peanut (Arachis hypogaea L.) seeds during germination is an important breeding goal of the peanut industry. Bacterial communities in the spermosphere soils may be of special importance to seed germination under salt stress, whereas extant results in oilseed crop peanut are scarce. Methods: Here, bacterial communities colonizing peanut seeds with salt stress were characterized using 16S rRNA gene sequencing. Results: Peanut spermosphere was composed of fo

Abstract:
Bacteria of the genus Bacillus are known for their ability to mineralize organic phosphorus compounds. Phytates constitute up to 60–80% of the total plant phosphorus and almost 50% of soil organic phosphorus. Phytates phosphorus is unavailable for plants. Bacillus can synthesize phosphatases both wide spectrum of action, and highly specific phytases that catalyze the hydrolysis of phytates. Therefore, the aim of this work was to study the growth and phytase activity of Bacillus subtilis IMV B-7023, which is the component of the ”Azogran” complex bacterial preparation for plant growing.

Abstract:
AbstractSoil P pools are strongly driven by microbial activities, and vice versa, P pools shape bacterial communities and their functional potential. Biological soil crusts (biocrusts) represent a microbial hotspot for nutrient turnover. We compared biocrusts and bulk soil samples from different temperate beech (Fagus sylvatica L.) forests representing a gradient in soil texture, nutrient concentrations, and pH values at biocrust peak biomass. We measured the total and plant-available P and N concentrations and assessed the bacterial potential to mineralize (phoD, phnX), solubilize (gcd), and

Abstract:
The soil microbial component plays a critical role in maintaining the soil functionality, performing several vital functions such as soil formation, decomposition of dead and decayed organic matter, circulation of macro and micro elements and transformation of toxic chemicals into non-toxic forms. Various Bacillus species, including B. megaterium, are known to fix atmospheric nitrogen. To ensure nitrogen fixation and diversity analysis of diazotrophs, the most widely used gene marker is nifH, which is responsible for synthesis of proteins of the nitrogenase complex.

Abstract:
Bacteria of the Bacillus genus can synthesize specific phytase enzymes. This property is especially important for soil bacteria. It helps to mineralize phytin and phytates and to provide these bacteria and plants (in the root zone of which they live) with the available phosphorus. Our previous studies have demonstrated that the Bacillus subtilis IMV B-7023 strain exhibits a phytase activity and can use phytate as a nutrition source. It is a component of the «Azogran» complex bacterial preparation for crop production. As known, abiotic environmental factors can influence the phytase activity of

Abstract:
Ultisols has problems of low availability of nutrients, especially phosphorus. To improve soil phosphate and P fertilizer efficiency, it is necessary to develop biofertilizer such as phosphate solubilizing microbes. Phosphate solubilizing microbes (PSM) have the capability of dissolving soil phosphorus which have been adsorbed and can mineralize organic P to become inorganic P, hence increasing the avalibility of P in the soil. Phosphate solubilizing bacteria (Pseudomonas mallei and Pseudomonas cepacea) and phosphate solubilizing fungi (Penicillium sp. and Aspergillus sp) were selected based o
