Morphological and metabolic characterization of a new species of strictly anaerobic rumen fungus:<i>Neocallimastix joyonii</i>

Abstract

A new strain of strictly anaerobic fungi was isolated from the rumen of sheep. This strain is characterized by a polycentric thallus, an extensive and polynuclear rhizomycelium, polyflagellated zoospores with gamma particle-like bodies. We propose to assign this strain in a new species: Neocallimastix joyonii.
