“…Inoculating Trichoderma can effectively control plant diseases caused by Botrytis cinerea [9], Fusarium oxysporum [10], Colletotrichum gloeosporioides [11] and other pathogens. Trichoderma also protects plants against drought stress [12] and heavy metal (Pb and Cd) stress [13]. In addition, Kulandaivelu et al [14] reported that Trichoderma can also enhance soil enzyme activity and nutrient elements as a biostimulant.…”

Trichoderma spp., which widely exist in nature, are always used as plant growth-promoting stimulants. However, there is little reporting about the combined use of Trichoderma strains to promote growth of plants. We explored two different Trichoderma strains (Trichoderma atroviride LX-7 and Trichoderma citrinoviride HT-1) and a mixture of the two on the growth-promoting effects of pakchoi. In this study, in vitro-promoting traits of two Trichoderma strains were determined, and six treatments were used: T. atroviride LX-7, T. citrinoviride HT-1, different mixtures of these two (1:1, 1:2 and 2:1) and no inoculation in the seed germination and pot experiment. The results showed that T.atroviride LX-7 and T. citrinoviride HT-1 had the ability of siderophore and indol acetic acid (IAA) production, and LX-7 had the capacity for potassium solubilization. The highest seed germination percentage (GP), germination energy (GE), germination index (GI), vitality index (VI) and growth of radicles and plumules was observed in the LX-7 + HT-1 (1:1) combination, the highest biomass and quality of plants was observed in the LX-7 + HT-1 (1:2) inoculation (followed by a single LX-7 or HT-1 strain inoculation), while the lowest values were obtained in the untreated seeds or plants. On the basis of this study, combined use of two Trichoderma strains had greater benefits for growth and quality of pakchoi, making this formulation attractive for future field applications.

“…Heavy metals eliminating from AR or GW inoculated by T. asperellum may be due to the presence of the efficacy groups such as carboxylic, hydroxyl, amine, and amide in fungal cells. These explanations were given in a recent study (Manna et al 2020). Analysis of organics of un-inoculated AR (C) and inoculated AR (T) by T. asperellum using GC indicated significant removal for the majority of tested compounds after treatment process, as shown in Table 3 and Figs.…”

“…AR and sewage water (SW) have become available in large quantities due to the increase in population and the rational and intensive use of fresh water. Therefore, these are being considered as carbonyl in fungi play a critical role during bioremediation of heavy metals from water sources (Manna et al 2020). In this sense, the application of AR in irrigation of plants without any treatment is often associated with some health risk.…”

Water safety and security has become a great problem in recent years, as the shortage of water resources in most countries is becoming an increasingly serious issue. Therefore, searching for new water sources or treating contaminated water has become a major requirement to covering the shortage of fresh water. The current study evaluated the impact of Trichoderma asperellum on the physicochemical characterization of agricultural run-off (AR) compared with groundwater (GW). Chemical oxygen demand (COD), biological oxygen demand (BOD5), ammonia, total nitrogen (TN), and total dissolved salts (TDS) of AR were higher than that of GW with 90, 90.2, 91.9, 78, and 61.6%, respectively. The addition of T. asperellum to AR caused the COD, BOD5, ammonia, TN, and TDS to decrease 47.2, 39.2, 16.2, 12.9, and 4.8%, respectively. Contents of metals in AR or GW were decreased by T. asperellum. Microbial analysis of soil irrigated by AR in contrast to irrigated by GW showed the presence of a high number of bacteria (32 × 106 CFU), actinomycetes (18 × 104 CFU), and fungi (13 × 104 CFU). Trifolium alexandrinum growth and its antioxidant enzymes activities (catalase, superoxide dismutase, and ascorbate peroxidase) were enhanced by AR inoculated by T. asperellum compared with un-inoculated AR or GW.

“…Por otro lado, biofiltros basados en Aspergillus heteromorphus fueron los más eficientes para eliminar el Cu y el Cr de los compost de RSOU (20%). Biofiltros basados en Trichoderma viride, Aspergillus heteromorphus, Rhizomucor pusillus y Aspergillus flavus fueron igualmente efectivos para provocar la toxicidad de Zn (∼30%) y Ni (> 30%) (Manna et al, 2020).…”

Fungal biomass potential: production and bioremediation mechanisms of heavy metals from municipal organic solid waste compost

et al. 2023

The compost produced based on municipal/urban organic solid waste (RSOM/U), is a valuable resource as a biofertilizer for agriculture, gardening, forestry and especially for soil remediation, whose production contributes to sustainable development through recycling of organic matter and nutrients. However, due to the raw materials used, the compost can have a significant content of heavy metals such as: cadmium (Cd), lead (Pb), arsenic (As), mercury (Hg) and selenium (Se), and contaminants such as potentially toxic trace elements that harm human health. These components can accumulate in plant tissues by absorption, giving rise to the possibility of being bioavailable to humans and animals. The fungal bioremediation of heavy metals in RSOM/U compost is highly efficient, cost-effective, available and friendly to the environment, therefore the removal of metals through this technique is a priority, if the purpose is to use it in agricultural soils. This review summarizes the studies based on the potential of fungal biomass for the bioremediation of heavy metals in RSOM/U compost, reporting information on RSOM/U-based compost, fungal biomass production and mechanisms of bioremediation of heavy metals by fungal biomass. In conclusion, the bioremediation of heavy metals using the fungal biomass in RSOM/U compost, with adequate segregation of raw material, coupled with bioremediation, could improve the removal of heavy metals in RSOM/U compost, and could be an ecological and viable alternative, which must be valued by intensifying its use.
