“…In contrast, the control sample's values ranged from 6.26 to 5.83. The A. resinae fungus is able to synthesize organic acids, including citric, oxalic, succinic, glutaric, and pyruvic acids this ability could be the reason for the pH values decrement on days 25 and 50 [5,10]. Additionally, it is expected that the fungus will transit from its constant growth phase to the stage of cell death or lysis due to the reduction of carbon resources and mineral components in the culture media, which may be the cause of the increase in pH values on day 75.…”

“…The process of microbial corrosion on metals, including aluminium, iron, copper, etc., and their alloys is carried out by various microorganisms, and fungi are among the signi cant ones in corrosion [4]. Aspergillus niger, Fusarium spp., Penicillium spp., and Amorphotheca resinae are some of the fungal species that contribute to microbial corrosion; A. resinae is the most signi cant and harmful fungus in corrosion among others [5] as it corrodes aluminum fuel tanks and is resistant to hostile environments thanks to the abundance of spores it produces [5,6].…”

Amorphotheca resinae is a fungus that particularly corrodes aeronautical aluminum alloys, leading to economic issues in various industries. This study aims to investigate the effects of this fungus on the corrosion of four different aluminum alloys, namely 2024, 7075, 5083, and 3105, after 25, 50, and 75 days through scanning electron microscopy (SEM), confocal laser scanning microscopy (CLSM), 3D profilometry, weight loss (%) measurement, energy dispersive spectrometry (EDS), electrochemical impedance (EIS), and pH changes. After 25 days, the 2024 alloy had the highest mycocorrosion rate (1.3417 mpy), while alloy 3105 had an undetectable value on this day. According to the EIS test, the 3105 alloy had the highest level of resistance (1.12×105 Ω.cm²) to corrosion, while the 2024 alloy was the most susceptible (7138 Ω.cm²). The qualitative data from SEM, CLSM, and 3D profilometry also confirmed the quantitative findings where the surface pits on the 2024 alloy were deeper than those of other alloys. Overall, the results showed that the lowest and highest corrosion rates mediated by A. resinae belonged to 3105 and 2024 alloys, respectively. These findings could have significant implications for industries that use aluminum alloys and might help in developing strategies to prevent or control biocorrosion.

“…Panaeolus subbalteatus is one of the most common sources of psilocybin, used in medical treatment. The kerosene fungus, Amorphotheca resinae (anamorph: Hormoconis resinae ), which was isolated from both leaves and flower buds, damages jet fuel, diesel, petroleum and creosote‐treated wood, but may have useful environmental applications in remediation of hydrocarbon contaminated sites (Rafin & Veignie, 2018).

Monk fruit (Siraitia grosvenorii) is an herbaceous perennial vine of the Cucurbitaceae family cultivated commercially mainly in southern China. There is very little information available about the fungal endophytes in monk fruit. In this study, monk fruit plants were grown from seeds in a research greenhouse at Kwantlen Polytechnic University in British Columbia, Canada to explore the abundance and diversity of their fungal endophytes. Fungal endophytes were isolated from seeds, seedlings, mature monk fruit plants, and fruits, and cultured on potato dextrose agar and water agar media. Isolates were identified by microscopic examination and BLAST comparison of ITS sequences to published sequences in GenBank. At least 150 species of fungal endophytes representing 60 genera and 20 orders were recovered from monk fruit tissues. Non‐metric multidimensional scaling (NMDS) was carried out to explore the similarity of fungal communities among roots, stems, leaves, flowers, fruits, and seeds based on fungal orders. Our study showed that monk fruit plants are a rich source of fungal endophytes with the greatest abundance and diversity in leaves. This work has deepened our understanding of the intricate interactions between plants and fungi that sustain ecosystems and underpin plant health and resilience.

“…The first step involves the entry of hydrocarbons into the cell by apparently active transport, although the mechanism of this process is not yet fully understood. Then, with the help of the enzymes alkane-monooxygenase, fatty alcoholoxygenase, and fatty aldehyde dehydrogenase, the process of alkane metabolism from hexadecane to hexadecanoic acid (palmitic acid) occurs, which, in turn, is involved in lipogenesis in fungal cells [ 27 ].…”

The Use of Mycelial Fungi to Test the Fungal Resistance of Polymeric Materials

et al. 2023

There are two main themes in the research on the biodegradation of industrial materials by mycelial fungi. The challenge of reducing environmental pollution necessitates the creation of biodegradable polymers that allow microorganisms, including mycelial fungi, to degrade them to low-molecule soluble substances. Additionally, to minimize the biodegradation of industrial materials while they are operating in the environment, there is a need to produce fungi-resistant polymer compositions. The fungal resistance of industrial materials and products can be assessed using a specific set of mycelial fungi cultures. Test cultures selected for this purpose are supported in the All-Russian Collection of Microorganisms (VKM). This review addresses the principle of culture selection to assess the fungal resistance of industrial materials and evaluates the results of the tests using these cultures.
