“…Even fungus-like protists such as slime molds or myxomycetes could be involved in the biosorption of heavy metals [10]. Interestingly, the genus Trichoderma are among those fungal taxa that were reported resistant to many toxic compounds, including fungicides, herbicides, and other organic pollutants and, in some cases, can degrade these toxic contaminants [11,12]. The toxic trinitrotoluene (TNT) was degraded by T. viride [13].…”

“…may play an important role in an eco-friendly metal removal technology and have acquired an exceptional credit as part of a sustainable approach to bioremediation [17]. It is also worth mentioning that, unlike other pollutants, heavy metals can be removed from wastewater by a biosorbent through different mechanisms, such as: (i) chemical transformations involving phase changes, (ii) bioaccumulation, which includes metabolism-dependent processes leading to the metal transport into the fungal cells, and (iii) biosorption, which is a surface mechanism that does not involve any metabolic process [11,12]. The latter mechanism is considered to be the most significant in metal removals through fungal biomass and can be attributed to ion exchange, coordination, or covalent bonding to the cell wall.…”

Nickel contamination is a serious environmental issue that requires immediate action. In this study, 23 strains of Trichoderma were isolated from terrestrial and marine environments and identified using a polyphasic approach of morphological characterization and ITS gene sequence analysis. The Trichoderma strains were tested for their tolerance and biosorption of nickel. Our results showed the growth of all Trichoderma strains on Trichoderma Selective Medium (TSM) with 50–1200-ppm nickel, indicating their tolerance of this heavy metal even at a relatively high concentration. Six Trichoderma strains (three isolated from terrestrial substrates and three from marine substates) had the highest radial growth on TSM with 50-ppm Ni. Among these fungal isolates, Trichoderma asperellum (S03) isolated from soil exhibited the best growth after 2 days of incubation. For the biosorption of nickel, the accumulation or uptake efficiency by the six selected Trichoderma was determined in Potato Dextrose Broth (PDB) supplemented with 50-ppm Ni using a Flame Atomic Absorption Spectrophotometer (AAS). The percent uptake efficiency of the three strains of T. asperellum (S03, S08, and LL14) was computed to be up to 66%, while Trichoderma virens (SG18 and SF22) and Trichoderma inhamatum (MW25) achieved up to 68% uptake efficiency. Observation of the Trichoderma strains with Scanning Electron Microscopy (SEM) before and after the absorption of nickel showed very minimal damage on the hyphal and conidial surface morphology, but changes in the colonial characteristics were observed. Our study highlighted the potential of terrestrial and marine strains of Trichoderma for the bioremediation of nickel pollution.

“…It has been shown that fungi and bacteria are capable of metabolizing DDT in this way, and the biodegradation pathways utilizing this method have been established. The strains of bacteria and fungi that degrade DDT have been identified as an alternate pathway for microbial attack in aerobic environments [ 18 , 29 , 53 , 71 , 106 ].…”

“…The breakdown of DDT insecticides frequently produces both toxic and non-toxic intermediates, which should be taken into consideration when developing a remediation strategy. Microbes, such as fungi, bacteria, microalgae, and others, are reported for DDT breakdown and used as bioweapons to fight DDT chemicals and caught the researcher's attention in recent years [ 18 , 19 ]. DDT degradation is dependent on natural reactions in the environment, such as chemical, biological, and physical.…”

“…Because of low toxicity to mammalian cells, high insecticidal efficacy, low environmental persistence, and relatively low potential to induce resistance of insects, the pyrethroid compounds are represented by 20% of the World’s insecticide markets [ 9 ]. The hydrophobic characteristic of pyrethroid compounds not only causes the tight binding with soil organic matter and particles, but also prevents the passage of these compounds to groundwater and thus forming residues that ultimately decrease soil fertility, hinder plant growth, and disturb the soil microbiota [ 10 , 11 , 12 ].…”

Herein, bacterial isolate HIS7 was obtained from contaminated soil and exhibited high efficacy to degrade pyrethroid insecticide cypermethrin. The HIS7 isolate was identified as Lysinibacillus cresolivuorans based on its morphology and physiology characteristics as well as sequencing of 16S rRNA. The biodegradation percentages of 2500 ppm cypermethrin increased from 57.7% to 86.9% after optimizing the environmental factors at incubation condition (static), incubation period (8-days), temperature (35 °C), pH (7), inoculum volume (3%), and the addition of extra-carbon (glucose) and nitrogen source (NH4Cl2). In soil, L. cresolivuorans HIS7 exhibited a high potential to degrade cypermethrin, where the degradation percentage increased from 54.7 to 93.1% after 7 to 42 days, respectively. The qualitative analysis showed that the bacterial degradation of cypermethrin in the soil was time-dependent. The High-Performance Liquid Chromatography (HPLC) analysis of the soil extract showed one peak for control at retention time (R.T.) of 3.460 min and appeared three peaks after bacterial degradation at retention time (R.T.) of 2.510, 2.878, and 3.230 min. The Gas chromatography–mass spectrometry (GC–MS) analysis confirmed the successful degradation of cypermethrin by L. cresolivuorans in the soil. The toxicity of biodegraded products was assessed on the growth performance of Zea mays using seed germination and greenhouse experiment and in vitro cytotoxic effect against normal Vero cells. Data showed the toxicity of biodegraded products was noticeably decreased as compared with that of cypermethrin before degradation.
