Isolation, purification, and characterization of a polygalacturonase produced in Penicillium solitum-decayed 'Golden Delicious' apple fruit.
Polygalacturonase (PG) was extracted and purified from decayed 'Golden Delicious' apple fruit inoculated with Penicillium solitum. Ammonium sulfate, gel filtration, and cation exchange chromatography were used to purify the enzyme. Both chromatographic methods revealed a single peak corresponding to PG activity. The purified PG most likely originates from the fungus because PG activity from hea...
متن کاملGenome Sequence of Penicillium solitum RS1, Which Causes Postharvest Apple Decay
Penicillium species cause postharvest decay, commonly known as blue mold, in pome fruits, such as apples and pears. To devise novel strategies to prevent and reduce economic losses during storage, the genome sequence of Penicillium solitum RS1 is reported here for the first time.
متن کاملPenicillium solitum produces a polygalacturonase isozyme in decayed Anjou pear fruit capable of macerating host tissue in vitro.
A polygalacturonase (PG) isozyme was isolated from Penicillium solitum-decayed Anjou pear fruit and purified to homogeneity with a multistep process. Both gel filtration and cation exchange chromatography revealed a single PG activity peak, and analysis of the purified protein showed a single band with a molecular mass of 43 kDa, which is of fungal origin. The purified enzyme was active from pH...
متن کاملThe Effect of Fungicides on Mycelial Growth and Conidial Germination of the Ginseng Root Rot Fungus, Cylindrocarpon destructans
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...
متن کاملblue mold (penicillium expansum) decay resistance in apple cultivars, and its association with fruit physicochemical traits
relative resistance of 43 iranian as well as introduced apple cultivars to blue mold (penicillium expansum) was studied within years 2010-2011. the fruit physicochemical traits were also evaluated as measures of potential resistance to decay. local p. expansum strains were isolated from decayed apple fruits and the most aggressive isolate (5,000 spores ml-1) used as inoculum. fruits were wound-...
