Abstract

Although bioluminescence is documented both anecdotally and experimentally, the parameters involved in the production of fungal bioluminescence during wood colonization have not been identified to date. Here, for the first time, this work develops a methodology to produce a hybrid living material by manipulating wood colonization through merging the living fungus Desarmillaria tabescens with nonliving balsa (Ochroma pyramidale) wood to achieve and control the autonomous emission of bioluminescence. The hybrid material with the highest bioluminescence is produced by soaking the wood blocks before co-cultivating them with the fungus for 3 months. Regardless of the incubation period, the strongest bioluminescence is evident from balsa wood blocks with a moisture content of 700–1200%, highlighting the fundamental role of moisture content for bioluminescence production. Further characterization reveals that D. tabescens preferentially degraded hemicelluloses and lignin in balsa wood. Fourier-transform infrared spectroscopy reveals a decrease in lignin, while X-ray diffraction analysis confirms that the cellulose crystalline structure is not altered during the colonization process. This information will enable the design of ad-hoc synthetic materials that use fungi as tools to maximize bioluminescence production, paving the way for an innovative hybrid material that could find application in the sustainable production of light.

利用白腐真菌 Desarmillaria Tabescens 生产生物发光木材
虽然生物发光在轶事和实验中都有记载,但在木材定殖过程中产生真菌生物发光所涉及的参数迄今尚未确定。在此,这项研究首次开发出一种方法,通过将有生命的真菌 Desarmillaria tabescens 与无生命的巴沙木(Ochroma pyramidale)合并,操纵木材定殖,生产出一种杂交活体材料,从而实现并控制生物发光的自主发射。在将木块与真菌共同培养 3 个月之前,先将木块浸泡,就能生产出生物荧光最高的杂交材料。无论培养时间长短,含水量在 700-1200% 的轻木木块发出的生物荧光最强,这说明含水量对生物荧光的产生起着至关重要的作用。进一步的特性分析表明,D. tabescens 优先降解轻木中的半纤维素和木质素。傅立叶变换红外光谱显示木质素减少,而 X 射线衍射分析证实纤维素晶体结构在定殖过程中没有改变。这些信息将有助于设计以真菌为工具的临时合成材料,最大限度地提高生物发光的产量,为创新的混合材料铺平道路,这种材料可应用于可持续的光生产。
