『風化における菌類の役割』


(Abstract)
 No rock at the Earth's surface escapes weathering. This process is the primary source of all the essential elements for organisms, except nitrogen and carbon. Since the onset of terrestrial life, weathering has been accelerated under the influence of biota. The study of biological weathering started at the end of the 19th century. Although the role of bacteria (Eubacteria, Archaea) has attracted a lot of interest, until recently the role of fungi has largely been neglected. More recently, however, fungal weathering has become an increasingly important focus of biogeochemical research.』

(要旨)
 地表で風化を逃れられる岩石はない。この過程は、窒素と炭素を除いて、生物にとってすべての必須元素の主要な供給源である。陸上生物の始まり以来、風化は生物の影響下で加速されてきた。生物学的風化の研究は19世紀末に始まった。細菌(真正細菌、古細菌)の役割は大きな関心を呼んできたが、最近まで菌類の役割はほとんど無視されてきた。しかし、ごく最近、菌類による風化は生物地球化学的研究の重要な焦点にだんだんなってきた。』
