Amylolytic enzymes produced by the fungus Colletotrichum gloeosporioides in rice semi-solid fermentation
Amylases are enzymes that hydrolyze starch, releasing several products including dextrines and small polymers of glucose units. This work investigated the capacity of the endophytic fungus Colletotrichum gloeosporioides of producing the amylolytic enzymes ï¡-amylase and glucoamylase through fermentation in semi-solid medium of residues of the processing of rice, without supplementation. The ï¡-amylase...

Survey of Spilocaea oleagina, causal agent of olive leaf spot, in North of Iran
Olive leaf spot or peacock spot, caused by the fungal pathogen Spilocaea oleagina, can cause reduced growth and yield in olive trees (Olea eurapaea). Investigations were carried out during 2007-2010 to measure the prevalence and severity of olive leaf spot in the northern olive growing regions of Iran. The susceptibility of ten cultivars (Amygdalifolia, Blaidy, Koronakei, Mary, Manzanillo, Mission, Rooghany,...

Anti-mycobacterium activity from culture filtrates obtained from the dematiaceous fungus C10
The aim of this work was to increase the concentration of substances with anti-mycobacterium activity in culture filtrates obtained from the dematiaceous fungus C10. An experimental design was employed to study the effect of glucose, potato infusion and Senna reticulata infusion. The anti-mycobacterium activity was determined by evaluating the growth of bacteria in culture medium containing “culture...
