Article Synopsis
  • Elevating microbial loads in soil from organic waste contamination can lead to new soil-borne pathogens and disruptions in nutrient cycling.
  • Atmospheric-pressure non-thermal plasma gas was tested and found to inactivate over 90% of bacterial cells and fungal spores in treated samples, significantly reducing microbial presence.
  • Plasma treatment also improved soil fertility, boosting spinach plant growth and nitrate levels, while only slightly affecting microbial diversity, suggesting it could be an effective soil sanitation method.

In this study, we aimed to examine the growth, physiological and biochemical status, and responses to salinity stress of bok choy ( subsp. ) cultivated in a hydroponic system with a plasma-treated solution. Plasma gas generated using a cylindrical dielectric barrier discharge or air (control) was injected into Hoagland nutrient solution once a week for different durations (0, 5, and 10 min).

While the biological role of naturally occurring nitric oxide (NO) in filamentous fungi has been uncovered, the underlying molecular regulatory networks remain unclear. In this study, we conducted an analysis of transcriptome profiles to investigate the initial stages of understanding these NO regulatory networks in , a well-established model filamentous fungus. Utilizing RNA sequencing, differential gene expression screening, and various functional analyses, our findings revealed that the removal of intracellular NO resulted in the differential transcription of 424 genes.

Although molecular regulation of cellulolytic enzyme production in filamentous fungi has been actively explored, the underlying signaling processes in fungal cells are still not clearly understood. In this study, the molecular signaling mechanism regulating cellulase production in was investigated. We found that the transcription and extracellular cellulolytic activity of four cellulolytic enzymes (, , , and ) increased in Avicel (microcrystalline cellulose) medium.

Article Synopsis
  • Researchers investigated the use of radio-frequency electromagnetic fields (RF-EMF) to boost the production of α-amylase, an enzyme produced by a filamentous fungus, addressing challenges in industrial enzyme production like low efficiency.
  • Exposure to RF-EMF for 10 minutes significantly increased total protein concentration and α-amylase activity by 1.5-3 times compared to control samples after 16 hours of incubation.
  • The study found that RF-EMF exposure enhanced the levels of α-amylase mRNA and led to increased vesicle accumulation and transcription of genes related to protein trafficking, while intracellular calcium levels rose without altering membrane potential.

For the industrial-scale production of useful enzymes by microorganisms, technological development is required for overcoming a technical bottleneck represented by poor efficiency in the induction of enzyme gene expression and secretion. In this study, we evaluated the potential of a non-thermal atmospheric pressure plasma jet to improve the production efficiency of cellulolytic enzymes in , a filamentous fungus. The total activity of cellulolytic enzymes and protein concentration were significantly increased (1.

In addition to being key pathogens in plants, animals, and humans, fungi are also valuable resources in agriculture, food, medicine, industry, and the environment. The elimination of pathogenic fungi and the functional enhancement of beneficial fungi have been the major topics investigated by researchers. Non-thermal plasma (NTP) is a potential tool to inactivate pathogenic and food-spoiling fungi and functionally enhance beneficial fungi.
