  • A first, we made white strain 'S line' adaptable to elevated temperature after collected brown strains were characterized with culture characterization on temperature and their monokaryons isolated at the high temperature were crossed with white strain. These S line monokaryons were crossed again with other monokaryons derived from a commercial white. As a result of successive crossing, finally a new variety 'Baengno' was developed. The optimum temperature of mycelial growth was $25^{\circ}C$ but it needed to adjust to $18{\sim}20^{\circ}C$ when incubated at the bottle cultivation. It brought incubation period shortening as 21 days saved 2~3 days when compared with other white varieties. The optimum temperatures of fruiting body initiation and development were almost same to others like as $14^{\circ}C$ and $7^{\circ}C$, respectively. Fruiting body of 'Baengno' was pure white even developed from crossing with brown strains. 'Baengno' was a good variety with high quality and high productivity characterized as quite even budding habit, long stipes and hemi-spherical pilei. This variety needed more air ventilation and had to be adjusted its cultivation environment for the good cultivation.

  • Effects of sangwhang mushroom (Phellinus linteus) powder and extract on quality of wet noodle were investigated by adding sangwhang mushroom powder at 2% (w/w: II) of wheat flour and extract at 17 (v/w: III) and 34% (v/w: IV) based on flour source, respectively. Significant decreases were found in L values of dough and noodle, while a and b values increased in proportion to addition of sangwhang mushroom. Addition of sangwhang mushroom decreased volume of cooked noodles, but increased turbidity of soup. Tensions of cooked noodle samples of II, III, IV, and control were 12.17, 17.61, 17.57, and 14.90g, respectively. Sensory properties, including color, flavor, taste, and texture, of noodles added with sangwhang mushroom extracts (III, IV) were significantly superior to control (I) and noodle added with powder (II). These results suggest addition of sangwhang mushroom extract is more suitable than powder for noodle processing.

  • Breads were prepared from wheat flour supplemented with oyster mushroom (Pleurotus ostreatus) powder, and effects of the supplementation of oyster mushroom powder on dough rheology and bread quality were examined. The initial pasting temperature in viscoamylograph increased, but peak and final viscosities decreased with the increased amount of oyster mushroom powder. The gradual increase of water absorption, dough development time and mixing tolerance index, and decrease of dough stability with the increased amount of oyster mushroom powder were obtained by farinographs. The supplementation of oyster mushroom powder had an effect on the bread making, resulting in an increase of loaf weight and a decrease of loaf volume. The rough and coarse crumb texture with dark color was observed with the increased amount of oyster mushroom powder. The firmness of bread crumb containing oyster mushroom powder was increased during storage periods. Sensory evaluation revealed that the addition of $1\%$ oyster mushroom powder could be supplemented to make an acceptable quality of bread.

  • The oyster mushroom (Pleurotus ostreatus) is one of the most important edible mushrooms worldwide. The mechanism of P. ostreatus fruiting body development has been of interest both for the basic understanding of the phenotypic change of the mycelium-fruiting body and to improve breeding of the mushrooms. Based on our previous publication of P. ostreatus expressed sequence tag database, 1,528 unigene clones were used in macroarray analysis of mycelium, fruiting body and basidiospore developmental stages of P. ostreatus. Gene expression profile databases generated by evaluating expression levels showed that 33, 10, and 94 genes were abundantly expressed in mycelium, fruiting body and basidiospore developmental stages, respectively. Among them, the genes specifically expressed in the fruiting body stage were further analyzed by reverse transcription-polymerase chain reaction and Northern blot to investigate temporal and spatial expression patterns. These results provide useful information for future studies of edible mushroom development.

  • Four species of Trichoderma causing green mildew of Agaricus bisporus were isolated from 38spots of mushroom growing areas in Korea. These are T. koningi, T. lignorum, T. glaucum and an unidentified species, and their frequencies of occurrence are $50\%,\; 32\%,\; 13\%; and\; 5\%$ respectively. All of these species grew well in potato dextrose, Waksman's and Richard's solution, and preferred acid (pH. 4) to neutral. The temperature in mushroom trouse should be kept at $15^{\circ}C$ during cropping period, not only for the high yield of mushroom but also for the prevention of green mildew of mushroom caused by Trichoderma spp . T. lignorum was killed in soil on an exposure of 60 minutes at $70^{\circ}C$ and when exposed for 30minutes at $80^{\circ}C$. Peak heat procedure of compost eliminated T. lignorum and T koningi.

  • In Korea, the oak mushroom (Lentinula edodes) is highly preferred by consumers in the food industry and makes up about 97.7% of the total forest mushroom production. This indicates that the oak mushroom is an important non-timber forest product in Korea. Recently, the breeding and development of new cultivars of L. edodes have been actively initiated, and the development of molecular markers that are able to identify and discriminate the new cultivars is crucial for protecting the breeder's rights. This study was carried out to develop a cleaved amplified polymorphic sequence (CAPS) marker for the identification and discrimination of a new cultivar, Sanmaru 2ho from the 37 other oak mushroom cultivars. A single nucleotide polymorphism (SNP) was identified at the $1,803,483^{rd}$ position of scaffold2 in the genome of Sanmaru 2ho. The amplified DNA containing the SNP of Sanmaru 2ho was uniquely not cleaved by the restriction enzyme, Hha I, and thus Sanmaru 2ho was successfully distinguished from the other oak mushroom cultivars.
