Aa. Zohri et Sm. Saber, NEW SOURCES OF CYTOCHALASIN-A AND CYTOCHALASIN-B FROM DEMATIACEOUS HYPHOMYCETES, Letters in applied microbiology, 19(1), 1994, pp. 37-39
One hundred isolates of 27 species belonging to 13 genera of dematiace
ous hyphomycetes were screened for production of cytochalasins A and B
. Most of these isolates (94) were obtained from Assiut University Cul
ture Collection, Botany Department, Faculty of Science, Assiut Univers
ity, Egypt; three isolates from CBS, The Netherlands; two isolates fro
m DSM, Germany; and one isolate from IMI, UK. The results revealed tha
t 10 isolates of six species representing five genera of fungi produce
d cytochalasins A and/or B. These species are Alternaria chlamydospora
, Cochliobolus spicifer, Diplococcum spicatum, Phoma herbarum, Phoma m
ultipora and Setosphaeria rostrata. This is the first report for the p
roduction of cytochalasins A and/or B by these species of dematiaceous
hyphomycetes.
