متن کاملByssotoxin A, a secondary metabolite of Byssochlamys fulva.
Byssochlamys fulva, isolated from corn, was grown on nutrient-amended shredded wheat medium for 14 days at 25 C. Crude solvent extract from these cultures was toxic to brine shrimp, chicken embryos, and rats. The extract was slightly inhibitory to the germination of of pea seeds, but was nontoxic to ten species of bacteria and one of yeast. One metabolite was isolated, given the trivial name by...
متن کاملThe pectic enzymes of the fungus Byssochlamys fulva.
It was reported by Beavan & Brown (1949) that cultures of By8aochlamy8 fulva Olliver & Smith produced protopectinase, but neither polygalacturonase nor pectin esterase; they concluded that B. fulva produced a disaggregating enzyme, which lowered the viscosity ofpectin solutions, without the formation of free reducing groups. A re-investigation of the problem has been made, and in a preliminary ...
متن کاملDeath of microbial cells: rate constant calculations.
The previously published procedure for calculation of rate constants associated with the death of microbial cells is shown to be so sensitive to variation in experimental data as to render it impractical for this application. The only obvious modification to the published procedure met with only limited success. It is concluded that a fresh search should be undertaken for the solution to this f...
متن کاملEnumeration of byssochlamys and other heat-resistant molds.
Methods for the detection of low numbers of heat-resistant molds on fruits were studied by using cultures of Byssochlamys and a number of unidentified mold isolates. Ascospore dormancy had a marked effect on viable recoveries, and the medium in which ascospores were heated influenced activation rates. Best results were obtained when fruit homogenates were heated for 60 min at 70 C in Concord gr...
