This study hypothesized that geographic segregation of certain extreme natures the same kind could be an indicator access to new natural microbial resources. Root-layer fungi and soil properties native well-conserved volcanic topographies from two geographically segregated ocean islands beside Korean Peninsula were analyzed. Four sampling sites represented volcanoes’ unique characters (tuff layer, caldera, steep cliffs) examined. A total 1356 operational taxonomic units classified into 7 phyla 196 genera obtained. Soil analysis showed sand proportion varied 32.0–57.4%, silt, 39.4–64.8%. The tuff layer terrain was only as silt soil. Corg contents ranged 2.78–15.12%; TN, 0.159–0.843; salinity, 0.001–0.019; pH, 5.0–7.4. larger island area, less oceanic salinity inflow, but TN decreased, pH increased. Shannon diversity index 4.81–5.23 higher at or center islands. As (distance) increased, taxa commonly identified decreased. Thus, isolation features (e.g., islands) may a preferential clue accessing broader range potential

The fungal green synthesis of nanoparticles (NPs) has gained great interest since it is a cost-effective and easy handling method. process simple because fungi secrete metabolites proteins capable reducing metal salts in aqueous solution, however the mechanism remains largely unknown. aim this study was to analyze secretome Trichoderma harzianum strain during mycobiosynthesis zinc iron nanoparticles. Different profiles secreted by fungus grown culture media or filtrate were observed through SDS‒PAGE LC‒MS/MS analysis identifying 99 304 proteins, respectively. Particularly, metabolic processes stress response mainly oxidoreductases, identified. Successfully, ZnO FeO NPs synthesized characterized transmission electron microscopy, energy dispersive X-ray spectroscopy, dynamic light scattering, thermogravimetric, FTIR analysis. revealed organic compounds acting as probably capping agents. This research first report which proteomic identifies multiple enzymes involved biogenic NP biosynthesis from T. harzianum, its role clearly demonstrated formation zincite magnetite

Introduction Alternaria solani is a challenging pathogen in the tomato crop globally. Chemical control rapid approach, but emerging fungicide resistance has become severe threat. The present study investigates use of culture filtrates (CFs) three species Trichoderma spp. to this disease. Methods Highly virulent A. strain and fungal strains viz., T. harzianum (Accession No: MW590687), atroviride MW590689) longibrachiatum MW590688) previously isolated by authors were used study. efficacy mitigate early blight disease tested under greenhouse field conditions, experiments conducted different seasons 2020 using variety “doucen”. Results discussion CFs , significantly inhibited vitro mycelial growth (62.5%, 48.73%, 57.82%, respectively, followed 100%). In GC–MS analysis CF volatile compounds harzianic acid (61.86%) linoleic (70.02%) hydroxymethylfurfural (68.08%) abundantly present. Foliar application considerably reduced severity (%) all treatments, (18.03%), (31.91%), (23.33%), infected (86.91%), positively affected plant biomarkers. greenhouse, plants treated with demonstrated higher flavonoids after 6 days inoculation, whereas phenolic increased 2 days. CF-treated antioxidant enzymes, i.e., phenylalanine ammonia-lyase (PAL) peroxidase (POD), 4 days, polyphenol oxidase (PPO) was healthy controls. open both as compared naturally plants, exhibited fruit yield than results conclude that can be potential biocontrol candidate promising alternative for sustainable production.

Nanocompounds are widely used in many fields such as environmental, medicine, or agriculture. Nowadays, these nanocompounds mainly synthesized by chemical methods, causing environmental pollution and potential health problems. Thus, microorganisms have been investigated nanoparticle green biosynthesizers. The main research is focused on the synthesis of nanoparticles (NPs) using algae, yeast, bacteria, fungi. Among them, fungi most used, due to their simple effective mycosynthesis. Fungi well other organisms involved NPs use secondary metabolites (SMs) mediate catalyze reactions produce metal (MNPs) being able act capping agents producing different physicochemical characteristics biological activities MNPs. various for mycosynthesis
