Abstract
In mid-logarithmic phase, cells of Neurospora crassa contain numerous small vacuoles, about the size of mitochondrial These vacuoles apparently fuse and develop into larger vacuoles in old cultures. The vacuoles, which contain high concentrations of basic amino acids — arginine, Ornithine, and lysine — and approximately equal amounts of anionic charges present as polyphosphate, are believed to function as storage reservoirs for nitrogen and phosphate (Weiss 1973; Cramer et al. 1980). Indeed, under conditions of nitrogen or phosphate depletion the vacuolar reserves can be mobilized and used for cell maintenance (Legerton and Weiss 1979). Because the vacuoles contain a majority of the organism’s hydrolytic enzymes and have an internal acid pH, they presumably also function like animal cell lysosomes (Matile 1978).
