船舶木材甲虫（鞘翅目：甲虫科）生长在木材中的共生真菌异节甲属。雌成虫具有携带真菌的器官（菌囊），产卵时将共生体存款到木材上。幼虫获得共生体，在木材中挖掘隧道，并以隧道壁上生长的共生体为食。由于木蠹蛾利用木材作为幼虫的栖息地，真菌共生体可能会利用不可消化的木材相关糖。然而，它们同化木材相关碳源的能力仍然未知。此外，除了革皮样Elateroides dermestoides外，没有报道过与异甘草酸相关的真菌群落。在这里，我报告说，船舶木材甲虫。源自日本的扇角藻含有五种真菌。对一株E.回收了扇角菌、丝状真菌和酵母菌的菌落。DNA分析表明它们是异囊藻属，兰基胡Ambrosiozyma llanquihuensis，Ambrosiozymasp.，Cyberlindnerasp.，和拟青霉属当木材相关的碳同化能力的五种真菌中的四种：异囊菌属，Am. llanquihuensis，Cyberlindnerasp.，和拟青霉属，他们之间的能力是可变的。单孢霉属同化半乳糖和半乳糖醛酸。还有赛博林蛇。从玉米中强烈同化的木聚糖。还有赛博林蛇。同化纤维二糖。所有的真菌同化葡萄糖，甘露糖和木糖。这些结果表明，与多种具有不同碳同化能力的真菌物种的联合可能有助于E. flabellicornis实现有效的营养摄入量的空间有限的隧道内营养贫乏的木材。
Ship timber beetles (Coleoptera: Lymexylidae) grow symbiotic fungi of the genusAlloascoideain wood. The female adults possess fungus-carrying organs (mycetangia) and deposit the symbiont onto wood during oviposition. The larvae acquire the symbiont, excavate a tunnel into wood, and feed on the symbiont growing on the tunnel walls. As lymexylids use wood as a larval habitat, it is possible that the fungal symbionts can utilize indigestible wood-associated sugars. However, their abilities to assimilate wood-associated carbon sources remain unknown. In addition, no lymexylid-associated fungal communities have been reported except forElateroides dermestoides. Here, I report that the ship timber beetleE. flabellicornisoriginating from Japan harbored five fungal species. When microbial isolation was conducted from mycetangia of a female adult ofE. flabellicornis, colonies of filamentous fungi and yeasts were recovered. DNA analyses revealed that they wereAlloascoideasp.,Ambrosiozyma llanquihuensis,Ambrosiozymasp.,Cyberlindnerasp., andSaccharomycopsissp. When wood-associated carbon assimilation abilities of four of the five fungal species:Alloascoideasp.,Am. llanquihuensis,Cyberlindnerasp., andSaccharomycopsissp., were tested, the abilities were variable among them. OnlySaccharomycopsissp. assimilated galactose and galacturonic acid.Alloascoideasp. andCyberlindnerasp. strongly assimilated xylan from corn.Saccharomycopsissp. andCyberlindnerasp. assimilated cellobiose. All of the fungi assimilated glucose, mannose, and xylose. These results suggest that the association with multiple fungal species with various carbon assimilation abilities may help the larvae ofE. flabellicornisto achieve efficient nutrient intake in space-limited tunnels within nutrient-poor wood.
