The molar percentage of guanine + cytosine (% GC) in the DNA from 25 yeast-like fungi related to the genus Geotrichum has been measured. This criterion together with the biochemical characteristics allow the division of the species into 3 groups: one group resembling G. candidum (% GC: 31.5--42) and

✦ Synopsis
DNA base compositions of representative (type) strains of Moniliella, Trichosporonoides and Hyalodendron were determined. Within Trichosporonoides over 16% variance was found. Most species separated well, but M. suaveolens showed considerable heterogeneity. The standard 2% G + C differences for species distinction is probably not applicable to these yeasts. The new combination M. pollinis is proposed for M. tomentosa var. pollinis on the basis of slight ecological, morphological and physiological differences, supported by a marked difference in % G + C.

The guanine + cytosine content (GC) of DNAs of 9 strains of pediococci and 6 strains of aerococci was determined using different physicochemical methods. It was found that the GC content of DNA of the pediococci ranged from 37.8 to 41.2~ while that of the aerococci varied from 42.0 to 43.20/0 . The
The D N A base composition of the photosynthetic prokaryote Prochloron was determined (on samples collected from the natural environment) to be 40.8mo1% GC. The sharp differential melting curve indicated the absence of significant quantities of contaminating D N A from other organisms. The genome si
