“…Saprotrophic fungi are known to have enzymes that degrade plant materials. For example, Aspergillus, Acanthophysium, Phallus, Penicillium, and Trichoderma are high in β-glucosidase, cellulase, chitinase, and proteases [68][69][70]. In addition, fungi (e.g., Aspergillus) associated with marine isopods Limnoria lignorum and Sphaeroma serratum have higher cellulase activity than bacteria from the same host [71].…”

The symbiotic relationship between macroorganisms, such as plants and animals, and the microorganisms in their environment plays a crucial role in shaping their physiology and ecology. Thus, many studies have examined microbial symbiosis in relation to plants, humans, and insects. However, little is known about the microbial diversity associated with isopods. Hence, in this study, we investigated the fungal diversity associated with two species of terrestrial isopods, Armadillidium nasatum and A. vulgare. In this study, we used a metabarcoding approach to compare fungal diversity between the two species for the first time. Our results indicated that A. nasatum had significantly greater mycobiome alpha diversity than A. vulgare. In contrast, fungal communities (beta diversity) did not differ significantly between hosts, except in beta dispersion of relative abundance. The majority of fungi identified belonged to Ascomycota and Basidiomycota, phyla that are dominated by saprotrophs. In conclusion, our findings shed light on the fungal communities associated with Armadillidium species, providing valuable insight into the biology of terrestrial isopods.

The terrestrial isopod, a crustacean order that has successfully transitioned from aquatic to land ecosystem, functions as a soil bioengineer and plays a crucial role in ecological decomposition. While there has been comprehensive documentation of bacterial associations with isopods, suggesting their contribution to digestive processes, the fungal component of isopods remains a less-explored dimension. Expanding our fundamental exploration into terrestrial isopods, we investigated whether the fungal community in Armadillidium vulgare is more significantly influenced by host sex or habitat using high-throughput sequencing-based internal transcribed spacer region amplification. Our findings revealed that the isopod mycobiome structure and taxonomic composition are predominantly shaped by the host's habitat rather than its sex. While the fungal richness of the mycobiome varied based on isopod sex, the co-occurrence network exhibited distinct variations dependent on both habitat and host sex. Finally, we observed a complete overlap of core mycobiomes based on isopod sex and identified fungal residents that are consistently distributed in a manner specific to either the habitat or host sex. In conclusion, we assert that community assembly of the isopod mycobiome in an untouched ecosystem is more significantly influenced by location than sex. We contend that this offers a fundamental groundwork, laying the cornerstone for future investigations into terrestrial isopods — pivotal agents in ecological decomposition within ecosystems.

Cellulase is an eco-friendly biocatalyst, and its demand is growing in many industrial applications such as food, textile, paper, and bioenergy. Strains with a high cellulase activities are the starting point for the economic production of cellulase. In a previous study, Acanthophysium sp. KMF001 with high cellulase production ability was selected among 54 wood-rotting fungi. In this study, we evaluated the cellulase productivity of Acanthophysium sp. KMF001 quantitatively and analyzed its taxonomic location using a genetic method. Acanthophysium sp. KMF001 showed high cellulase productivity similar to that of Acanthophysium bisporum and was much better than A. bisporum in specific enzyme activity. The 28S rRNA sequence of Acanthophysium sp. KMF001 was similar to that of Acanthophysium lividocaeruleum MB1825, with 98.40% homology. Phylogenetic analysis suggested that Acanthophysium sp. KMF001 is a new strain. In this study, we propose a new strain with high cellulase productivity.
