The objective of the present study was to investigate the optimal nutritional requirements for mycelial growth and sporulation of entomopathogenic fungus Aschersonia aleyrodis Webber by orthogonal layout methods. Herein the order of effects of nutrient components on mycelial growth was tryptone > Ca(2+) > soluble starch > folacin, corresponding to the following optimal concentrations: 1.58% Sol...
BACKGROUND Mushroom showed pellet, clump and/or filamentous mycelial morphologies during submerged fermentation. Addition of microparticles including Talc (magnesium silicate), aluminum oxide and titanium oxide could control mycelial morphologies to improve mycelia growth and secondary metabolites production. Here, effect of microparticle Talc (45 μm) addition on the mycelial morphology, fermen...
A total of four isolates of Stemphylium botryosum infected lentil were collected from lentil plants showing blight symptoms and grown at different areas of Bangladesh. The isolates were characterized in terms of cultural, morphological and physiological parameters. The isolates varied significantly in their cultural, morphological and physiological traits of colony color, shape, texture, conidi...
To obtain rich in organic forms of zinc extracts of Lentinus edodes, possessing putative higher immunostimulating properties than actually used, mycelia were cultivated in zinc(II) enriched media. Culture media were enriched in zinc in concentration ranging from 0 to 90 microg mL(-1), added to the medium before inoculation. Total zinc concentration in submerged cultivated mycelial biomass has b...
Natural geranyl compounds are known to exhibit important biological activities. In this work a series of geranylphenols were synthesized to evaluate their effect on the mycelial growth of Botrytis cinerea. Geranyl derivatives were synthesized by direct geranylation reactions between the corresponding phenol derivatives and geraniol, using BF3.OEt2 as catalyst and AgNO3 as secondary catalyst. Pr...
the dry bubble disease, caused by lecanicillium fungicola, is an important fungal disease of white button mushroom in iranian mushroom production farms. twenty-three isolates of the pathogen collected in iran and identified as l. fungicola var. fungicola, were compared for genetic polymorphism, diversity in growth rate and virulence. ten universal rice primers (urp) were used to evaluate the ge...
The amount of soybean agglutinin (SBA) detectable by radioimmunoassay in seeds of resistant cultivars to Phytophthora megasperma var. sojae was approximately twice that of susceptible cultivars. SBA was preferentially released at earlier times (6-9 hours) and in higher amounts in the imbibate from resistant cultivars as compared to susceptible cultivars. The lectin in the imbibate was immunolog...
in this study, anti alternaria solani effects of essential oils of 11 medicinal and aromatic plant species belonging to four families collected from the west of iran were investigated based on agar dilution method with five replications at concentration of 1.0 µl/ml. the results showed that the highest inhibitory effect belonged to oliveria decumbens, cinnamomum zeylanicum, carum copticum and t...
