  • A microbial strain capable of producing lactic acid was isolated and identified as Streptococcus faecium. During the incubation of the isolated bacterium in a synthetic medium (Petterson broth), the optimal temperature was 36 to 39$^{\circ}C$ and the cell concentration at stationary growth phase was 2.1${\times}$10$\^$8/ viable cells/ml. When it was dried in vacuum and diluted with avicel, the Viability of Streptococcus faecium in physiological saline solution was decreased to 80% after incubation for 48 hr at 37$^{\circ}C$, whereas the viability was above 90% after incubation for 1 hr at 40$^{\circ}C$ and the viability in M buffer solution (pH 4.5∼9.0) at 37$^{\circ}C$ was above 95%. From these data it was concluded that the isolated microbe must be adoptible for pharmaceutical preparation such as solid dosage form.

  • In order to elucidate the systematic taxonomy and genetic characters of Canoderma lucidum, cultural characteristics of the fungus were investigated. Mycelial growth of Ganoderma lucidum were favorable on oat meal agar medium, and optimum temperature and pH of the medium for mycelial growth were $30^{\circ}C$ and 5.5-6.0 respectively. Irradiation of white fluorescent lamp inhibited mycelial growth and critical time for inhibition of mycelial growth was 4-8 hours. Concentric zones and mycelial strands of Ganoderma lucidum was induced by irradiation of white fluorescent lamp and formation of mycelial sectors was influenced by nutrient source of media and irradiation of white fluorescent lamp. These characters were different among the isolates, but no relationship was observed between these characters and the fruiting body type of the fungus. Basidiospores were formed directly from the mycelium cultured on artificial media without producing fruit body.

  • Preliminary creel-holding test of live anchovies which are to be used as bait for the skipjact fishery, was conducted on the fish caught by set net and lift net. They were held in the creels constructed with bamboo frame and minnow netting, during the period of Oct. 24-Nov. 28 in 1972. If was found that the survival rate of the creel-held anchovies varied by the size of fish, the towed distance and speed of fish-carrying creel in which the fish were accomodated after catchi. 1. The survival rate of the medium size anchovies, 7.8-9.6cm in length and 4.6-4.8 g in weight, was $70-92\%$ during the holding period of 20-35 days. Whereas, only $16\%$ of juvenile anchovies, 5.3cm in length and 1.0 g in weight, were survived for 19 hours after catch. 2. During the time of transport, the farther and faster the creel containing fish were towed, the less fish were survived in the subsequent holding period. 3. Though both the set net and lift net could be fairly used to catch live anchovy, no decision between these two gears could be made in this experiment to determine the superiorness for the subsequent survival rate.

  • Among the 34 strains of Nicotinophiles selected in the previous experiments, strain NCT27 identified with Pseudomonas putida and strain NCT30 identified with Arthrobacter oxydans biotype nan thus were Investigated for optimization of growth conditions for nicotine degradation and other cultural characteristics. The compositions of optimized medium were to be following: $KH_2PO_4$ 2.Ogr, KCI 5.Ogr, $MgSO_4$.$7H_2O$ 20mg, $MnSO_4$.$6H_2O$ 0.2mg, $FeSO_4$.$7H_2O$ 1.Omg, Col$^{++}$ (Cobalt Acetate),2.O$\gamma$, N1$^{++}$ (NiSO4,6H2O) 0.5$\gamma$, and yeast extract 80mg per liter. The optimum initial concentrations of nicotine for growth were 0.4% for Pseudomonas and 0.1% for Arthrobacter, respectively. The optimum temperature and pH were 3$0^{\circ}C$ and 7.0 for both of strains. The pH of culture medium of Pseudomonas was changed from acidic condition to basic one in going from the logarithmic growth phase to the stationary growth phase. In contrast with Pseudomonas, it remained constant in case of Arthrobacter. The growth of Arthrobacter was completely inhibited in the nicotine concentration of 0.7&. However, Pseudomonas could grow even in the nicotine concentration of 1.0%. Moreover, it could grow successfully in the tobacco extract media as well as media containing carbon and nitrogen sources other than nicotine. The maximum rates of nicotine degradation were to be 1.22 gr./hr./liter for Pseudomonas and 0.186 gr./hr./liter for Arthrobacter, respectively.
