โœฆ Synopsis

Geotrichum candidum grew filamentously in batch culture. Hyphal fragmentation occurred during growth; myeelial fragments in the early part of the stationary phase had a mean length of 300 to 400 ~zm. The dry weight, total hyphal length, number of hyphal tips and turbidity of the culture all increased exponentially at about the same specific growth rate. The results suggested the existence of a functional unit of growth consisting of a hyphal tip associated with a constant mean length of hypha. The hyphal growth unit was defined as the ratio between the total hyphal length and number of hyphal tips in the culture; for 0. candidum this unit was about 100 ~m long and its length remained constant when the organism's specific growth rate was varied by changes in temperature, carbon source or the incorporation of eyeloheximide in the medium.

## Abstract The metabolic activity of __Geotrichum candidum__ was investigated. The chromatographic analysis of the cell pool and of the acid hydrolysate revealed the presence of almost all the amino acids previously detected in other yeasts. The pool pattern was not greatly different from the acid
