Radix pseudostellariae L. is a common and popular Chinese medication. However, continuous monoculture has increased its susceptibility to severe diseases. We identified two pathogenic microorganisms, Talaromyces helicus M. (KU355274) and Kosakonia sacchari W. (KU324465), and their antagonistic bacterium, Bacillus pumilus Z. in rhizosphere soil of continuously monocultured R. pseudostellariae. N...

Bioslurry phase reactor augmented with ETP microflora was studied for the degradation of pendimethalin contaminated soil. The effect of substrate concentration on the process performance was evaluated in the slurry phase reactor operated in sequence batch mode under anoxic-aerobic-anoxic microenvironment with a total cycle period of 120 h. The performance of augmented slurry phase system was fo...

In this study, the impact of three different types of activated carbon (AC) on the bioaccessibility of 14C-phenanthrene in non-sterile and sterile soils was investigated. A single dose (1%) of each of the different AC (CB4, CP1 and AQ5000) was blended with soil spiked with 50 mg·kg−1 of 12C/14C-phenanthrene. The mineralisation of the 14C-phenanthrene was monitored over a 14 day incubation perio...

Soils contaminated with mineral oil hydrocarbons are often cleaned in off-site bioremediation systems. In order to find out which bacteria are active during the degradation phase in such systems, the diversity of the active microflora in a degrading soil remediation system was investigated by small-subunit (SSU) rRNA analysis. Two sequential RNA extracts from one soil sample were generated by a...

An abundance of hydrocarbon oxidizing microbes is found, not unexpectedly, in areas where extraordinary quantities of hydrocarbons exist in the biosphere. In particular, bacteria of the genus Mycobacterium develop in areas of oil and gas production and in areas of petroliferous gas seeps. One of these species, Mycobacterium paraffinicum n. sp., shows a high degree of specificity for petroleum h...

The plant surface, which is representative of the phylloplane and rhizoplane, is a characteristic habitat for microorganisms. In this review, the ecological roles of phytoepiphytic bacteria will be described. The phylloplane and rhizoplane, which are adjacent to the atmosphere and soil sphere respectively, accumulate topically and/or selectively release secondary metabolites that are specific t...

Invasive plant species can alter litter decomposition rates through changes in quality, environment conditions, and decomposer organisms (microflora soil fauna), but limited research has examined their direct impact on fauna. We assessed the abundance relative contribution of meso- macrofauna to a forest invaded by Ligustrum lucidum W.T. Aiton noninvaded subtropical mountain northwestern Argent...

Soil receptivity to arbuscular mycorrhizal (AM) fungi tests the capacity of a soil to favour the mycorrhizal development after inoculation. Thus, receptivity is a key criterion to assess whether the introduction of non-indigenous AM fungi will successfully improve plant growth. Two experiments were set up to investigate the receptivity of a moderately acidic wheat-growing soil of the Argentinea...

Probiotic therapy is based on the concept of normal healthy microflora. The development of novel means of characterising the gut microflora, in particular those based on the different levels of conservation in the ribosomal RNA sequences of different genera, have opened up new angles on the role of the gut microflora in health and disease. Components of the human intestinal microflora or organi...
