“…As seen in Table 1 , the major classes of phospholipids identified in T. harzianum cultures were PC and PE. This is in line with previous data on Trichoderma fungi [ 36 , 42 , 43 ]. The content of PC and PE were in the ranges of 15.50–66.44 and 29.85–73.84% of total cell phospholipids, respectively.…”

While there has been intensive research on the influence of microplastics (MPs) on aquatic organisms and humans, their effect on microorganisms is relatively little-known. The present study describes the response of the Trichoderma harzianum strain to low-density polyethylene (LDPE) microparticles. MPs, either separately or with metolachlor (MET), were added to the cultures. Initially, MP was not found to have a negative effect on fungal growth and MET degradation. After 72 h of cultivation, the content of fungal biomass in samples with MPs was almost three times higher than that in the cultures without MPs. Additionally, a 75% degradation of the initial MET was observed. However, due to the qualitative and quantitative changes in individual classes of phospholipids, cell membrane permeability was increased. Additionally, MPs induced the overproduction of reactive oxygen species. The activity of superoxide dismutase and catalase was also increased in response to MPs. Despite these defense mechanisms, there was enhanced lipid peroxidation in the cultures containing the LDPE microparticles. The results of the study may fill the knowledge gap on the influence of MPs on filamentous fungi. The findings will be helpful in future research on the biodegradation of contaminants coexisting with MPs in soil.

“…Membrane lipids are particularly sensitive to toxic chemicals in the surrounding environment. It has been well documented that toxic compounds induce qualitative and quantitative changes in the composition of membrane-forming lipids and thus disrupt the integrity of the cell membrane [ 70 , 71 , 72 ]. Omic methods, including lipidomics, have been used over the years to explore the mechanisms through which fungi adapt to stressful conditions.…”

“…In another study, an increase in the PC/PE ratio was observed in Metarhizium robertsii cultures exposed to atrazine [ 75 ] or Beauveria bassiana cultures exposed to insecticides λ-cyhalothrin, α-cypermethrin, and deltamethrin [ 76 ]. On the other hand, a study showed a decrease in the PC/PE ratio, possibly leading to a decrease in membrane fluidity in the biomass of Trichoderma harzianum IM 0961 exposed to 2,4-D [ 72 ] or M. robertsii treated with TBT [ 70 ]. This suggests that microorganisms use different strategies to alter phospholipid membranes to maintain cell stability in the presence of various environmental contaminants.…”

The ascomycete fungus Nectriella pironii, previously isolated from soil continuously contaminated by dye industry waste, was used for the biodegradation of phenanthrene (PHE), benz[a]anthracene (B[a]A), and benz[a]pyrene (B[a]P). The degradation of polycyclic aromatic hydrocarbons (PAHs) by N. pironii was accelerated in the presence of landfill leachate (LL) collected from the area of fungus isolation. The rate of cometabolic elimination of PHE and B[a]P in the presence of LL was, respectively, 75% and 94% higher than in its absence. LC-MS/MS analysis revealed that PAHs were converted to less-toxic derivatives. The parallel lipidomic study showed changes in membrane lipids, including a significant increase in the content of phosphatidylcholine (PC) (almost double) and saturated phospholipid fatty acids (PLFAs) and a simultaneous reduction (twofold) in the content of phosphatidylethanolamine (PE) and unsaturated PLFAs, which may have promoted the fungus to PHE + LL adaptation. In the presence of PHE, an intense lipid peroxidation (fivefold) was observed, confirming the stabilization of the cell membrane and its extended integrity. Determining the course of elimination and adaptation to harmful pollutants is essential for the design of efficient bioremediation systems in the future.

“…Most Trichoderma strains also produce volatile and non-volatile toxic metabolites that inhibit colonization by antagonized microorganisms; among these Trichoderma: A Biofertilizer and a Bio-Fungicide for Sustainable Crop Production DOI: http://dx.doi.org/10.5772/intechopen.102405 metabolites, the production of harzianic acid, alamethicins, tricholin, peptaibols, antibiotics, 6-penthyl-a-pyrone, massoilactone, viridin, gliovirin, glisoprenins, heptelidic acid and others have been described [47][48][49][50]. This phenomenon has been observed in various fungi including Trichoderma, which can produce a multitude of compounds with antagonistic properties including cell wall degrading enzymes such as cellulase, xylanase, pectinase, glucanase, lipase, amylase, arabinase, and protease, volatile metabolites such as 6-n-pentyl-2H-pyran-2-one (6-PAP) [51-53], and several antibiotics such as trichodermin, trichodermol, gliovirin, gliotoxin, viridin, herzianolide, pyrones, peptaibols, ethylene and formic aldehyde [50, 54,55]. In general, strains of T. virens with the best efficiency as biocontrol agents can produce gliovirin [50].…”

Trichoderma - Technology and Uses

Trichoderma has been studied widely. It has been found to play a major role in agricultural production. Around the world scientists and farmers have taken advantage of this knowledge. It is reported to improve plant growth of many crops such as tomato, lettuce, maize, beans, cabbage sugarcane and many more crops. There are two broad categories where Trichoderma plays a major role which is its use as a biofertilizer as well as a biofungicide. Its use as a biofertilizer has been aggravated by its ability to produce volatile compounds, ability to solubilize phosphates making them available to the plant. Moreover, farmers use it as a biofertilizer because it improves the uptake of macro and micro nutrients by the plant. As a biofungicide, Trichoderma is not to control many pathogens from various crops. This includes the control of pathogens such as Rhizoctonia, Phytophthora, Rhizoctonia, Sclerotinia, Phythium, Fusarium, Sclerotinia species and Galumannomyces. The mechanisms used by Trichoderma as a biofungicide includes, antibiosis, mycoparasitism, competitive advantage in the rhizosphere as well as priming of the crop self-defense mechanisms. The purpose of this book chapter is to highlight the importance of Trichoderma in agriculture as a biofertilizer and biofungicide.
