Acid phosphatase activities in a culture liquid and mycelial extract were studied in submerged cultures of the filamentous fungus Humicola lutea 120-5 in casein-containingmedia with and without inorganic phosphate (Pi). The Pi-repressible influence on the phosphatase formation was demonstrated. Significant changes in the distribution of acid phosphatase between the mycelial extract and culture ...

to study of biological control of charcoal rot of melon caused by macrophomina phaseolina, 187 isolates of fluorescens pseudomonas isolated of rhizosphere and soil of melon plants. then 12 isolates belong to i, iii and v biovars of p. fluorescens and b biovar of p. putida were selected for greenhouse experiments based on inhibition amount. pseudomonas isolates inhibited mycelial growth signific...

background and objectives: food contamination by aflatoxins is an important food safety concern for agricultural products. in order to identify and develop novel antifungal agents, several plant extracts and isolated compounds have been evaluated for their bioactivities. anti-infectious activity of piper betle used in traditional medicine of malaysia has been reported previously. materials and ...

Ginseng root rot caused by Cylindrocarpon destructans is the most destructive disease of ginseng. Six different fungicides (thiophanate-methyl, benomyl, prochloraz, mancozeb, azoxystrobin, and iprodione) were selected to evaluate the inhibitory effect on the mycelial growth and conidial germination of C. destructans isolates. Benomyl and prochloraz were found to be the most effective fungicides...

Entomopathogenic bacteria Xenorhabdus spp. produce secondary metabolites with potential antimicrobial activity for use in agricultural productions. This study evaluated the inhibitory effect of X. nematophila TB culture on plant pathogens Botrytis cinerea and Phytophthora capsici. The cell-free filtrate of TB culture showed strong inhibitory effects (>90%) on mycelial growth of both pathogens. ...

BACKGROUND AND PURPOSE Fusarium species are avid producers of secondary toxic and carcinogenic metabolites such as fumonisin. Contamination of food and feed products with fumonisin can be hazardous to the health of humans and animals and may lead to agricultural loss. Accordingly, in this study, we aimed to evaluate the effects of Candida parapsilosis on the growth and fumonisin production of F...

We studied the resistance of Cenococcum geophilum and Suillus granulatus isolates to NaCl during growth under axenic culture conditions. C. geophilum isolates displayed variations in NaCl resistance; mycelial growth of most isolates was inhibited above 200mM. All isolates of S. granulatus were tolerant to high NaCl content.
