AI Article Synopsis

  • Various strains of Aspergillus and Penicillium were treated with colchicine, EMS, or UV irradiation to enhance their ability to convert alpha-pinene to verbenol.
  • The best-performing variant was the UV-treated Aspergillus strain, achieving a significant 15-fold increase compared to the original.
  • Similarly, UV-treated Penicillium also showed strong results with an 8-fold increase, while changes in colony traits, spore size, and DNA content were observed across all variants.

Article Abstract

Variants of Aspergillus sp. and Penicillium sp. obtained after treatment with colchicine, ethyl methanesulphonate (EMS), or ultraviolet (UV) irradiation indicated varying levels of significant increases in their efficiency to transform alpha-pinene to verbenol. In case of Aspergillus sp. the UV-induced variant was the best performer with a 15-fold increase in biotransformation efficiency compared to the wild type. In case of colchicine and EMS-induced variants the biotransformation increases were 2- and 8-fold, respectively. The UV-induced variant of Penicillium sp. was capable of eight fold increase in efficiency while the colchicine- and EMS-induced variants were 1.5- and 2-fold, respectively. The variants were characterised with respect to changes in colony morphology, spore dimension, DNA content, and products formed, viz. verbenol and verbenone.

In the search for novel natural products with hepatoprotective effects against acetaminophen-induced acute liver injury, the marine-derived fungus WHUF0198 was investigated. Seventeen undescribed pyranopyridone alkaloids, aculeapyridones A-Q (-), were isolated by bioactivity-guided fractionation of an extract obtained by coculture of the WHUF0198 with the mangrove-associated fungus sp. DM27.

Jiangsu Provincial Key Lab for Solid Organic Waste Utilization, Key Lab of Organic-Based Fertilizers of China, Jiangsu Collaborative Innovation Center for Solid Organic Wastes, Educational Ministry Engineering Center of Resource-Saving Fertilizers, Nanjing Agricultural University, Nanjing, China.

Bacillus velezensis SQR9 or Trichoderma harzianum NJAU4742-amended bioorganic fertilizers might significantly improve the soil microbial community and crop yields. However, the mechanisms these microorganisms act are far away from distinctness. We combined amplicon sequencing with culturable approaches to investigate the effects of these microorganisms on pear tree growth, rhizosphere nutrients and microbial mechanisms.

Airborne microorganisms in hospitals present significant health risks to both patients and employees. However, their pollution profiles and associated hazards in different hospital areas remained largely unknown during the extensive use of masks and disinfectants. This study investigated the characteristics of bioaerosols in an urban general hospital during the COVID-19 pandemic and found that airborne bacteria and fungi concentrations range from 87±35 to 1037±275 CFU/m and 21±15 to 561±132 CFU/m, respectively, with the outpatient clinic and internal medicine ward showing the highest levels.

January 2025

Laboratory for Taxonomic Study and Collection of Cultures of Microorganisms, Gause Institute of New Antibiotics, St. Bolshaya Pirogovskaya, 11, 119021 Moscow, Russia.

In this study, two compounds have been isolated from the Arctic-derived fungus INA 13460. Structural elucidation, performed using 2D NMR and HR-ESIMS data, has identified the compounds as stereoisomers of secalonic acids, dimeric tetrahydroxanthones. The absolute configurations of these stereoisomers have been determined through conformational NMR analysis and circular dichroism spectroscopy.
