Effect of Water Potential on Mycelial Growth and Sporangial Formation by Pythium spp.
Sung, Jae-Mo ;
The Korean Journal of Mycology, volume 11, issue 3, 1983, Pages 105~108
The mycelial growth of Pythium graminicola, P. ultimum, P. rostratum was best at -3 osmotic potential. P. monospermum was best grown at -8 bars osmotic potential. Mycelial growth by Pythium spp. was prevented at -42 bars for P. graminicola, P. ultimum and P. monospermum. Sporangial formation by P. graminicola and P. ultimum was influenced by water potential in much the same way as mycelial growth: -3 bars was maximum and -42 bars or below was minimal. Pythium spp. tested was grown faster on PDA than other media including oat meal agar. P. ultimum was best grown on any media among Pythium spp. tested.
Studies on the
Activity of Whole Cell Aspergillus Phoenicis
Kim, Mal-Nam ;
The Korean Journal of Mycology, volume 11, issue 3, 1983, Pages 109~114
activity of Aspergillus phoenicis was studied using ONPG and lactose as substrate. It increased monotonically during the exponential growth phase and dropped rapidly at the beginning of the stationary one. It exhibited high tolerable temperature and acidic optimal pH which provides certain advantages from the industrial view point. Enzyme of
had more subsrate affinity for ONPG than for lactose and its apparent maximum activity was also higher with the former as substrate. Activity of this enzyme depended upon the conditions of immobilization. Optimum crosslinking reaction was occurred at pH 7.2 and 0. 35 vol. % of glutaraldehyde concentration.
Steroid Modification with Aspergillus Phoenicis : Effects of Solvents and Glucose
Kim, Mal-Nam ;
The Korean Journal of Mycology, volume 11, issue 3, 1983, Pages 115~119
The bioconversion of progesterone by Aspergillus phoenicis has been studied. The metabolism in the conditions of experiment gave
as main product. The concentration of
increased monotonically and leveled off after 40 hours of incubation. Addition of glucose into the medium reduced considerably the time for attaining limiting concentration of
. The increase in initial progesterone concentration did not affected the percentage of conversion nor the time required for termination of the reaction. But it could not be represented as first order reaction with respect to progesterone concentration. The degree of inhibition of enzymes by organic solvents depended upon the concentration of solvents. At low solvent concentration, acetone proved to yield the highest conversion.
Fruit-body Formation of Pleurotus florida on the Synthetic Medium

The Korean Journal of Mycology, volume 11, issue 3, 1983, Pages 121~128
Nutritional and physio-chemical conditions for mycelial growth and fruit-body formation of Pleurotus florida were determined in synthetic media. Mannitol and sucrose were good sugar substances for the mycelial growth and fruit-body formation whereas less mycelial growth and no fruit-body formation was obtained with arabinose, lactose and inulin. The optimum concentration of mannitol was about 2%. Peptone as a nitrogen sources resulted in a rapid mycelial growth and fruit-body formation with higher yield, but nitrite-nitrogens inhibited the mycelial growth. The higher yield was obtained with 0.2% peptone. Among the vitamins used, the greatest mycelial growth and fruit-body formation brought about by thiamine and folic acid.
at 0.2% and 0.02%, respectively, were effective for the mycelial growth and fruit-body formation, but other inorganic salts used were ineffective. The optimum temperature for mycelial growth and fruit-body formation were
, respectively, and light intensity of
and pH 6.0 appeared to be effective.
