“…In the present study, eight Al-resistant fungi were successfully isolated from the acidic forest soil, but no bacteria were isolated, which is consistent with the results of Kawai et al [13], suggesting that fungi were more resistant to acidity and Al toxicity [17]. As one of the most important components of soil ecosystems, soil microbes are involved in the degradation and purification of soil pollutants [18][19][20], and play crucial roles in the process of nutrient cycling and energy flow in the soil ecosystem. Furthermore, they enhance the stress tolerance of plants [11,21].…”

Acidic red soil from a forest in Jiangxi Province was selected to isolate aluminum (Al)-resistant microbes, from which eight fungi were isolated. Two strains (S4 and S7) were found to be extremely tolerant to Al concentrations of up to 550 mmol L -1 and could grow at low pH levels (3.20-3.11). Morphological and 26S rDNA sequence analyses indicated that strain S4 belonged to Eupenicillium, while strain S7 was an unclassified Trichocomaceae. Further investigation showed that both strains were endowed with the ability to resist Al; strain S4 accumulated such a substantial amount of Al that its growth was limited to a larger extent than strain S7. The lower amounts of Al adsorbed in the mycelium and the much larger amounts of Al retained in the medium, in addition to the color change of the culture solution, implied that these two strains may resist Al by preventing Al from entering the cell and by chelating Al by secreting unique metabolites outside of the cell.

“…No other researchers observed that the amount of zinc exert so strong influence on the incidence of any soil fungus. Although there are numerous works dealing with impact of heavy metals among them zinc, on the growth and activity of Trichoderma fungi [10,13,14,15,16], no characteristic difference in the reaction to zinc was found among Trichoderma species. Our data on the zinc reaction of T. harzianum species agree with that statement.…”

Abstract. The growth requirements of Trichoderma fungi that are wide spread saprotrophic soil microorganisms, are quite similar, therefore it is essential to define the environmental factor(s) along which they divide the available ecological niches. For this reason, we determined chemical and physical properties of 24 soil samples from different localities of Hungary, the presence of Trichoderma species and the relationships between two groups of data were analyzed with different statistical methods. The coexistence of 13 identified Trichoderma spp. proved to be a general phenomenon, which provided a good opportunity to explore the dividing environmental factors. Only redundancy analysis gave a reasonable model from 26 abiotic soil parameters. However, the number of variables was two times higher than that of species, thus the model was built in step-by-step process during which the explanation power of parameters was assessed with Monte Carlo permutation test. The best possible model of 13 soil properties explained 66.19 % of variance in the occurrence of Trichoderma species. Their positions in the triplots showed the separation of their niches along some of the investigated abiotic environmental variables. The available Zn-content had the highest explaining power however the in vitro zinc tolerance test did not justify its importance.

“…Analysis of REEs sorption to individual soil constituents could not only distinguish and measure the relative importance of the various soil constituents to REEs fate. This method has the advantage of avoiding the interference of background REEs in soil (Ledin et al, 1999).…”

“…In this paper, lanthanum, a major component in REEsmicrofertilizer, has been selected to represent rare earth elements. Five common soil constituents (quartz, feldspar, kaolinite, goethite, humic acid) have been chosen as adsorbents in consideration of their amount in soil or adsorption capacity (Ledin et al, 1999). Kaolinite is a major clay mineral in soil.…”
