1Cell walls of filamentous fungi – challenges and opportunities for biotechnology
Applied Microbiology and Biotechnology, Год журнала: 2025, Номер 109(1)
Опубликована: Май 24, 2025
Abstract The cell wall of filamentous fungi is essential for growth and development, both which are crucial fermentations that play a vital role in the bioeconomy. It typically has an inner rigid core composed chitin beta-1,3-/beta-1,6-glucans rather gel-like outer layer containing other polysaccharides glycoproteins varying between within species. Only fraction fungal species used biotechnological production enzymes, organic acids, bioactive compounds such as antibiotics large amounts on yearly basis by precision fermentation. Most these products secreted into medium must therefore pass through walls at high transfer rates. Thus, mutants have gained interest industrial enzyme production, although causal relationship productivity requires further elucidation. Additionally, extraction valuable biopolymers like chitosan from spent biomass, predominantly walls, represents underexplored opportunity circular Questions persist regarding effective their repurposing valorization processes. This review aims to address issues promote research understanding optimize use. Key points • highly complex important biotechnology. Cell show promising potential improve secretion. Recent studies revealed enhanced avenues chitin/chitosan biomass. Graphical

0Bioprospecting of endophytic fungi from semidesert candelilla (Euphorbia antisyphilitica Zucc): Potential for extracellular enzyme production
Journal of Basic Microbiology, Год журнала: 2024, Номер 64(7)

Abstract Endophytic microbial communities colonize plants growing under various abiotic stress conditions. Candelilla ( Euphorbia antisyphilitica Zucc.) is a shrub that develops functionally in arid and semi‐arid zones of Mexico; these conditions generate an association between the plant microorganisms, contributing to production enzymes as defense mechanism for resistance stress. The objective this research was isolate identify endophyte fungi candelilla bioprospection endophytic enzyme using by‐products. Fungi were isolated identified ITS1/ITS4 sequencing. Their potency index (PI) evaluated producing endoglucanase, xylanase, amylase, laccase. Fermentation carried out at 30°C 8 days 200 rpm, with measurements every 2 days, by‐products substrate. All exhibited higher cellulase, laccase activities on 2nd, 6th, 8th day fermentation, respectively, fermentation. fungus Aspergillus niger ITD‐IN4.1 showed highest amylase activity (246.84 U/mg), genus Neurospora cellulase activity, reaching up 13.45 FPU/mg, strain sp. ITD‐IN5.2 (3.46 U/mg). This work provides first report diversity E. its potential role production.

3The Effect of a Magnetic Field on the Enzymatic Activities of Common Airborne Aspergillus Strains Isolated from Indoor Environments
Aerobiology, Год журнала: 2025, Номер 3(1), С. 2 - 2

The aim of this study was to evaluate the effect an extremely low-frequency oscillating magnetic field on enzymatic activities common airborne Aspergillus sp. strains that were isolated from indoor environments. A D-optimal experimental design with three factors applied: density (0.5 2 mT), exposure time h), and (A. ellipticus, A. japonicus, flavus, fumigatus). response variables exoenzymatic indexes (cellulolytic, amylolytic, proteolytic, lipolytic, hemolytic) pH, as a measure organic acid production. ellipticus highest producer acids, japonicus pathogenic fumigatus. Different magnetobiological effects observed: enzyme secretion in remaining strains, we detected no appreciable (Ilip Iprot flavus), inhibition ellipticus; Icel Iamil japonicus; fumigatus), stimulation. Predictive quadratic models obtained, mT for h treatment regime influenced fungal activity. These physiological changes following could be during sporulation must thus considered aeromicrobiology studies. They can also beneficial obtaining industrial-use enzymes, but detrimental biodeterioration different materials human health.
