“…This is in accordance with investigations showing that the copper cation concentration at 0.75 mmol dm −3 promotes the growth of Trichoderma species. 13 Experiments performed on T. viride spore survival in CS/ ALG/(Cu+TV) revealed that during storage at room temperature the number of spores was almost constant in the smaller microcapsule, whereas in larger microcapsules somewhat increased (Table 1). It seems that smaller microcapsules were fully loaded with T. viride spores and there was no space for their germination.…”

“…In light of the importance of T. viride as a biocontrol agent, showing a high ability to accumulate and compatibility with macro-and micronutrients, 12,13 simultaneous encapsulation of copper cations and T. viride could give wider opportunities in both plant nutrition and protection. The aim of this work was to prepare chitosan/alginate microcapsules simultaneously loaded with copper cations and T. viride (CS/(ALG/(Cu +TV)) for plant protection and nutrition.…”

Novel chitosan/alginate microcapsules simultaneously loaded with copper cations and Trichoderma viride have been prepared and characterized. Information about the intermolecular interactions between biopolymers and bioactive agents was obtained by Fourier transform infrared spectroscopy. Encapsulation of T. viride spores and the presence of copper cations in the same compartment does not inhibit their activity. Microcapsule loading capacity and efficiency as well as swelling behavior and release depend on both the size of the microcapsule and bioactive agents. The in vitro copper cation release profile was fitted to a Korsmeyer-Peppas empirical model. Fickian diffusion was found to be a rate-controlling mechanism of release from smaller microcapsules, whereas anomalous transport kinetics controlled release from larger microcapsules. The T. viride spore release profile exhibited exponential release over the initial lag time. The results obtained opened perspectives for the future use of chitosan/alginate microcapsules simultaneously loaded with biological and chemical agents in plant nutrition and protection.

“…Also, they represent an alternative to conventional fertilizers and contribute to the conservation of soil biodiversity (Dominguez-Nuñez et al 2015). Soil microorganisms are getting more and more popular as bioremediation agents as well (Kavamura et al 2008Jovičić Petrović et al 2014;Atanasković et al 2015).…”

Surface mining causes major destruction of natural landscapes and ecosystems. The most fertile, surface soil layer is lost permanently, together with vegetation, wildlife, and micro flora. Post-mining areas are characterized with diverse edaphic, topographic, hydrographic conditions, which complicate land restoration. Successful establishment of forest ecosystems on such land depends mostly on selection of tree species. The chosen plants must be capable of tolerating a wide range of acidity, fertility, moisture, and have potential to ameliorate such substrates for more demanding species. But, reforestation of heavily damaged ecosystems, such as post-mining areas, demands a new approach in seedlings production. This new approach takes into account specific requirements of habitat and integrates them into "targeted production of planting material". A good strategy for successful reforestation of post-mining areas is the input of organic matter (compost, mulch). Also, current knowledge and experiences emphasize the potential of beneficial microorganisms such as, mycorrhizal fungi (MF) and plant growth promoting rhizobacteria (PGPR). The majority of studies that deal with beneficial interactions between trees and microorganisms are focused on the mycorrhiza, while plant growth promoting rhizobacteria are less present in silviculture. In this study, the focus is on the reforestation challenges of two mining basins, Majdanpek and Kolubara and suggests beneficial microorganisms as potential solution. The study presents results of several years' researches on plant response to the presence of mycorrhizal fungi and PGPR. The substrates used for plant growth were Majdanpek and Kolubara mine deposals. Mycorrhizal seedlings were grown in Majdanpek mine deposal, and at the end of the experiment they had 30% higher biomass in comparison to control (seedlings without mycorrhiza). Seedlings linked with fungi had a higher survival rate. Deposals from Kolubara Mining Basin were used as a substrate for seedlings inoculated with PGPR. In the first experiment, Scots pine and Norway spruce were inoculated with Azotobacter chroococcum, Bacillus megaterium, B. circulans, B. licheniformis, B. pumilus, B. amyloliquefaciens. Inoculation resulted with higher biomass production (Scots pine 43%, Norway spruce 34%). Similar results were obtained in the second experiment where Scots pine and black locust were inoculated with Bacillus licheniformis, Aeromonas hydrophila, Pseudomonas putida and Burkholderia cepacia. Both species had higher biomass (around 20%) in comparison to un-inoculated control. The results confirmed the fact that early establishment and successful growth of vegetation on devastated areas depends on the presence and activity of soil microbes. Microorganisms as a "nature's solution" pose the potential to alleviate reforestation challenges of anthropogenic devastated landscapes. Their presence and activity is crucial for ecosystem stability. In areas with compromised balance, their introduction is justified action fo...

“…There efficiency could be further enhanced by inoculation of selected rhizospheric microbes in the plant rhizosphere [18,19]. Petrovic et al [20] isolated a Cu tolerance Trichoderma species capable of scavenging toxic Cu from the soil. Preliminary success inspired several researches to search novel yet potential microbial inoculants which have multifaceted mode of action including scavenging of heavy metals toxicity from the contaminated soil and water.…”

Heavy Metals Scavenging Potential of Trichoderma asperellum and Hypocrea nigricans Isolated from Acid Soil of Jharkhand

Trichoderma asperellum (NAIMCC-F-03167) and Hypocrea nigricans (NAIMCC-F-03168) were isolated from the acidic soil of the vicinity of Litchi orchard, Ranchi, Jharkhand and were characterized on the basis of morphological, molecular and biochemical features. Both strains are fast growing, light to dark green, highly sporulative and have ability to cover 90 mm Petri dish within 96 h of inoculation. Biochemcial estimation of both isolates indicated significant cellulase and phosphate solubilisation activity. Highest cellulase activity was observed in T. asperellum (5.63 cm) followed by H. nigricans (5.10 cm) and phosphate solubilisation index was observed maximum in T. asperellum (1.93) followed by H. nigricans (1.39). Moreover, these isolates were molecularly identified on the basis of ribosomal DNA based sequences database and phylogenetic analysis in NCBI GenBank as T. asperellum (NCBI-KM 438015) and H. nigricans (NCBI-KJ910335). Negetive effect on sporulation of Lead (Pb) and Cadmium (Cd) was observed while in heavy metal scavenging potential, T. asperellum (88.9% Cd) showed highest scavenging potential followed by H. nigricans (87.2% Cd) while in Pb scavenging potential, H. nigricans (88% Pb) followed highest scavenging potential followed by T. asperellum (81.30% Pb) after 21 days of inoculation from 30 lg/ml heavy metals concentrated broth medium. If both potential bioagents can apply in Cd and Pb affected soil/water will be helpful in scavenging of heavy metals as well as management of phosphorus deficiency and soilborne fungal diseases.
