Abstract:

Seedlings of Pinusradiata D. Don. were grown in containers in three autoclaved soils and inoculated with three ectomycorrhizal fungi: Rhizopogonluteolus Fr. and Nord., Paxillusinvolutus Batsh. ex Fr., or Hebelomacrustuliniforme Quélet. General soil microfloras from four soils were added and ectomycorrhizal infection was assessed at 3 and at 4 months. Infection was enhanced or impeded by the soil microfloras, depending largely on the soil on which the plants were grown and on the mycorrhizal fungus. Enhancement of infection by added microflora was more frequent than reduction. The results are d

Abstract:

Phosphorus (P) scarcity poses a significant challenge to sustainable agriculture, impacting plant growth and crop productivity. While arbuscular mycorrhizal (AM) fungi have been extensively studied for their role in enhancing phosphorus acquisition, this review explores the potential of diverse microflora as alternative solutions. The diverse microflora groups, including rhizobacteria, actinomycetes, and cyanobacteria, contribute to phosphorus availability through various mechanisms. These microfloras produce organic acids, enzymes, and chelators that enhance phosphorus solubility and minerali

Abstract:

Soil is an excellent culture media for the growth and development of various microorganisms.

The amount proposition of different components in soil varies with localities in climate.

<p>All the biotechnologies intended for improvement of environmental conditions are based on the ability of microorganisms for hydrocarbon oxidizing. In the development of biotechnological approaches for soil re-cultivation the extent of soil pollution has to be taken into account. Among the advantages of a technology employing mineral nutrient substrates for enhancing the oxygenizing activity of soil microflora its cost-effectiveness is very important. When dealing with highly polluted soils, more complex methods for soil restoration are called for; however, these are much more labour-e

Abstract:

ABSTRACT Degradation of polycyclic aromatic hydrocarbons (PAHs) and survival of bacteria in soil was investigated by applying different inoculation protocols. The soil was inoculated with Sphingomonas paucimobilis BA 2 and strain BP 9, which are able to degrade anthracene and pyrene, respectively. CFU of soil bacteria and of the introduced bacteria were monitored in native and sterilized soil at different pHs. Introduction with mineral medium inhibited PAH degradation by the autochthonous microflora and by the strains tested. After introduction with water (without increase of the pore water sa

Abstract:

We studied the microflora of Quebec sphagnum peat moss samples taken from five different locations in a peat moss processing plant: soil, drying stacks, sedimented dust (walls and floor), and in bagged peat moss. Large numbers of microorganisms were found; the predominant ones were of the genus Monocillium (up to 112 × 106 colonies/g of dry peat) and the genus Penicillium (320 × 104 colonies/g dry weight). These moulds were more abundant in the processed peat moss than in the peat soil (e.g., Monocillium: soil, 138 × 103; processed peat, 112 × 106). Aspergillus spp. were absent in all five sam

Soil bacterial and fungal communities were investigated in relation to soil type and farm management practices after vegetation harvesting in autumn. Soils from fields cultivated with Phaseolus vulgaris (bean) and Pyrus comminus (pear) and nonarable, natural areas were studied. Microbial diversity was analysed using cultivation-dependent methods (isolation of pure cultures) and cultivation-independent methods (direct extraction of DNA from soil, followed by PCR amplification of the 16S rRNA and 18S rRNA genes). The use of cultivation-dependent methods revealed that there were no differences in

Aim: Soil represents one of the most diverse habitats found on our planet. Soil organisms play crucial roles within ecosystems by exerting influence over physical properties and processes, as well as contributing to carbon and energy fluxes and the cycling of nutrients. The activity and composition of soil organisms are significantly impacted by land use and land management practices. In this study, we examined the predominant functional groups present in soil two different soil management systems viz., organic and integrated nutrient management (INM). Methods: We collected soil samples

Abstract:

New Caledonian ultramafic soils have relatively high metal content, which normally induces toxicity in plants and microflora. The relationships between extractable metal concentrations, especially Ni and Co, and different microbiological factors were analysed by statistical methods. For this purpose, some physico-chemical and microbiological characteristics of 40 ultramafic soil samples were estimated: organic carbon, pH, extractable metals (Ni, Co, Fe, Mn and Mg), microbial density, total microbial activity and percentage of microorganisms tolerant to Ni.

The ecotoxicological effect of pesticide formulations at the concentration range of half of the normal field rate (0.5FR), normal field rate (FR), 2FR, 4FR and 8FR respectively on representative microflora and mesofauna soil sentinels was investigated. Inhibition effects over the 1, 2, 3 and 4 hr period of exposure in Winogradsky media were observed for microflora. Avoidance responses were observed for mesofauna in pesticide spiked soils after a 48 hr exposure period. Generally, there was a corresponding decrease in mesofauna population with increase in pesticide concentrations. The LC50 value

Abstract:

SynopsisThe evolutionary significance of natural fire disturbance regimes in the development of post-fire fungal and herb communities is examined. Before a fire the soil microflora exhibits a general fungistasis, microbial competition is great, nutrients are limiting, and carbonicolous ascomycetes are in a dormant phase. Also in mature chaparral shrub communities the soil microflora is implicated in soil toxicity that prevents seeds of some species from germinating in the interval between burns. Fire results in the deposition of ash and charred wood, a release of nutrients, the elimination of

Relative soil moisture for the territory of the Wadi El K'sob catchment area was estimated by using the Sentinel-1/Multispectral Instrument (MSI) and Landsat-8/Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) optical multispectral data. Elevation data of the sampling points range from 398 to 1081 meters
