“…The ones that are positively correlated with Tricholoma are small fungi with saprotrophic features, such as Umbelopsis or Trichoderma, which were reported to be the dominant genera of some mycorrhizal fungi. Trichoderma can increase the success rate of ectomycorrhizal infection [ 78 ]. Umbelopsis , which has the second-highest relative abundance biomarkers in PB, was also the dominant genus in the habitat of Tricholoma in Gyeongju in Southern Korea [ 79 ].…”

Soil origin, mycorrhizal plant partners and environmental factors affect the growth and development of SongRong (Tricholoma matsutake). In order to clarify the relationships of fungi–bacteria networks and various influence factors in the habitat of SongRong, we chose three collection sites with a Quercus mongolica pure forest (plot A without SongRong was used as the control sample site), Q. mongolica mixed Rhododendron dauricum (plot B) and Q. mongolica mixed with R. dauricum and Pinus densiflora (plot C). By using high-throughput sequencing, we obtained a total of 4930 fungal and 55501 bacterial amplicon sequence variants (ASVs) based on internally transcribed spacer ribosomal RNA (ITS rRNA) and 16S ribosomal RNA (16S rRNA) sequencing via the Illumina NovaSeq platform. In the habitat soil of SongRong (plot B and plot C), alpha or beta diversity and species compositions of fungi and bacteria were different from plot A. The fungal–bacterial networks follow the selection rule that few dominant genera account for the greater relative abundance. Forest types, but not the host itself, drove the fungal–bacterial networks of the forest soil, and soil physicochemical characteristics and texture affected their abundance. The abundance of Tricholoma was affected by the fungal and bacterial abundance in the habitat.

“…Isolate Tc-013 has similarities in colony appearance, hyphal branching morphology , and hyphal and spore diameter dimensions toTrichoderma esperellum (Sutarman, 2022;Sutarman, Jalaluddin, Li'aini, & Prihatiningrum, 2021). BLAST search results (NCBI, 2022) showed 100% similarity to T. asperellum (Sequence ID: MT102403.1).…”

The study’s goal is to find the best native fungus from rice husk waste so that a solid biofertilizer can be made with high-husk flour as a carrier material and an inert agent. This study was conducted on agricultural land in Seloliman Village, Trawas District, and Mojokerto Regency. Biofertilization and biological agent formulation activities carried out at Muhammadiyah University of Sidoarjo’s Microbiology Laboratory aided the research. The experiment was conducted using a factorial randomized block design. The first factor consisted of three treatments: no fungi, Trichoderma sp., and Aspergillus sp. The second factor consists of soil treatment and apical treatment. The six treatment combinations were repeated four times (24 samples). The variables measured comprised plant height, number of panicles, weight of grain per plant, weight of 100 grams of grain, and the efficacy of biological agents in improving plant growth and productivity. All data underwent analysis of variety and then an HSD test at the 5% significance level to identify disparities among treatments. The study reveals that isolates Tc-013 and As-022 were identified as Trichoderma esperellum and Aspergillus flavus or A. oryzae, respectively. The application of Trichoderma and Aspergillus caused a decrease in the intensity of disease symptoms, reaching 64.7% and 37.3%, an increase in plant height and number of panicles, and an increase in the weight of 100 grains of 59.89 and 49.35%, respectively, as compared to the control treatment where the fungus was not applied.

This study aims to determine the type of metabolites contained in the extraction of Ipomea carnea canopy biomass and its inhibitory effect in vitro against Trichoderma asperellum Tc-Jjr-02 which has been tested as an active ingredient in bio fungicides and biofertilizers. The initial stage of the research is the determination of the metabolites contained in the extract with methanol solvent through Gas Chromatography-Mass Spectrophotometry (GCMS) analysis. The next step was an in vitro test of the extract's inhibitory power to the growth of T. asperellum fungal colonies during the incubation period of up to 96 hours. The results of GCMS analysis of extracts with methanol solvents obtained 24 types of metabolites, some of which can inhibit fungal growth. Crude extract of canopy biomass of I. carnea at a concentration of 2% inhibited the growth of all Trichoderma isolates by 20.97±3.36% (Tc-Jjr-02), 38.15±32.59% (Tc-Sba-01), and 45.30±1.86% (Tc-Jro-01), while at a concentration of 20% inhibited isolates Tc-Sba-01 and Tc-Jro-01 were 35.19±4.90% and 42.59±1.85% in vitro at 96 hours after inoculation, respectively. The isolate of T. esperellum Tc-Jjr-02 has the potential to be formulated with I. carnea biomass as compost in the future.
