“…Interestingly, the results presented here show spont:weous formation of sclerotia without addition of any inducing agent(s). Several workers have obserbed that light affects sclerotium fo rmation in a number of fungi (Carlile, 1956;Heath and Eggins, 1965;Rai et al, 1967). The results of the present study, however, show no disti nct effect of light on sclerotium formation in Curvularia spp.…”

“…(Carlile, 1956); Aspergillus j aponicum (Heath and Eggins, 1965); Aspergillus spp. (Rai et al, 1967;Rudolph, 1962) and Sclerotium rolfsii (Gruelac h and Mohr, 1947;Mclellan et al , 1955). Different quality of li ght differentially affects sclerotium fonnation in Verticillium albo-atrum as blue light inhibits microscleroti al production while yellow, orange and red Light promote it (Kaiser, 1964).…”

“…Sclerotia produced in the temperature range of 25 to 35 "C were more compact, larger (1200 p in diameter), and more definite in shape than those produced at 15 "C. A. niger produced the highest number of sclerotia at 35 "C. Rudolph (13) reported that a strain of Aspergillus Jlavus produced sclerotia only at 38 "C, whereas Rai et a[. (12) reported that A. Jlavus produced abundant sclerotia at 27 "C.…”

AGNIHOTRI, V. P. 1969. Some nutritional and environmental factors affecting growth and production of sclerotia by a strain of Aspergillus niger. Can. J. Microbiol. 15: 835-840. The effects of two nutritional elements (carbon and sulfur) and two environmental factors (pH and temperature) on growth and sclerotial production of Aspergill~a niger were determined on a synthetic agar medium. The fungus grew and produced sclerotia under laboratory conditions on media containing wide ranges of carbon and sulfur sources. Of the 20 carbohydrates tested, only ribose, mannitol, and malonic, fumaric, and citric acids failed to induce production of sclerotia. A synergistic effect was observed on the formation of sclerotia when favorable and unfavorable carbon sources were supplied in different combinations. Of the 14 sulfur compounds tested, magnesium sulfate yielded the highest and sodium sulfite the lowest number of sclerotia. Raising the concentration of magnesium sulfate to 3 g/l increased the number of sclerotium initials and the number and dry weight of those which matured. In general, no correlation occurred between the number of sclerotia formed and their dry weights on different carbon or sulfur sources. Sclerotia were most numerous at pH 7.0 and 35 "C.
