effect of temperature and water activity on spore germination and mycelial growth of three fungal biocontrol agents against water hyacinth (eichhornia crassipes).to determine the effect of water activity (a(w) =0·880-0·960) and temperature (15-35°c) on the percentage of viable conidia and mycelial growth of three biocontrol agents effective against water hyacinth in mali: alternaria sp. isolate mlb684, fusarium sacchari isolate mln799 and cadophora malorum isolate mln715.201021143713
endoglucanase-producing fungi isolated from cape evans historic expedition hut on ross island, antarctica.early explorers of antarctica's heroic era erected wooden buildings and brought large quantities of supplies to survive in antarctica. the introduction of wood and other organic materials provided nutrient sources for fungi that were indigenous to antarctica or were brought in with the materials and adapted to the harsh conditions. seventy-two isolates of filamentous fungi were cultured on selective media from interior structural wood of the cape evans historic hut and 27 of these screened posit ...200616817929
an antarctic hot spot for fungi at shackleton's historic hut on cape royds.the historic expedition huts located in the ross sea region of the antarctic and the thousands of artifacts left behind by the early explorers represent important cultural heritage from the "heroic era" of polar exploration. the hut at cape royds built by ernest shackleton and members of the 1907-1908 british antarctic expedition has survived the extreme antarctic environment for over 100 years, but recent studies have shown many forms of deterioration are causing serious problems, and microbial ...201020386896
non-conventional methods for the control of post-harvest pear diseases.pears are highly perishable products, especially during the post-harvest phase, when considerable losses can occur. among the fungal diseases, blue mold caused by penicillium expansum, grey mould caused by botrytis cinerea, mucor rot caused by mucor piriformis are common on pear fruits. other (weak) pathogens like phialophora malorum, alternaria spp., and cladosporium herbarum tend to infect wounds and senescent fruits. a post-harvest fungicide treatment can reduce decay but effectiveness decrea ...200312694440
hydroxylated sclerosporin derivatives from the marine-derived fungus cadophora malorum.the marine-derived fungus cadophora malorum was isolated from the green alga enteromorpha sp. growth on a biomalt medium supplemented with sea salt yielded an extract, from which we have isolated sclerosporin and four new hydroxylated sclerosporin derivatives, namely, 15-hydroxysclerosporin (2), 12-hydroxysclerosporin (3), 11-hydroxysclerosporin (4), and 8-hydroxysclerosporin (5). the compounds were evaluated in various biological activity assays. compound 5 showed a weak fat-accumulation inhibi ...201020052971
cellulose degradation and cellulase formation by phialophora malorum.the formation of cellulases and beta-glucosidase and their location in the fungus phialophora malorum was studied on some different carbon sources. the cellulases were found to be partly cell-free and partly cell-bound during growth on cellulose and carboxymethyl-cellulose. glucose and cellobiose repressed the cellulase formation but a low carboxymethylcellulase activity was measurable on the glucose-grown mycelium. the unicellular stage did not appear to grow on carboxymethyl-cellulose or cellu ...197829588
