Yeast isolates were obtained from the hindgut of the lower termites Mastotermis darwiniensis (Mastotermitidae), Zootermopsis angusticollis, Zootermopsis nevadensis (Hodotermitidae), Neotermes jouteli (Kalotermitidae), Reticulitermes santonensis, Heterotermes indicola (Rhinotermitidae) and the roach Cryptocercus punctulatus (Prillinger et al. 1996). The monosaccharide composition of the cell wall, the ubiquinone system, partial sequencing of 18S ribosomal DNA and the ultrastructure of septal pores indicate that most yeast species belonged to the Endomycetales. They were assigned to the genera Candida, Debaryomyces, Pichia and Sporothrix. Other species showed affinities to the Basidiomycetes in particular to the genera Trichosporon. Between 107 and 5×108 yeastcells were found per ml gut contents in Zootermopsis angusticollis and Neotermes castaneus. Some isolates were able to hydrolyse cellulose or xylan (Schafer et al. 1996; Wenzel et al. 2002). The yeasts isolated from the hindgut can be considered symbionts.
