    Abstract: PURPOSE: New strain of Candidanorvegica, CRM-9802 (KCTC 8900P) containing high concentration of ribonucleic acid (RNA) is provided which is used to manufacture a nucleotide spice from RNA of Candida cell extract. CONSTITUTION: Soil sample is mixed with sterile saline and vortexed. The supernatant is plated on YM agar and incubated at 30°C for 24-48 hours. The isolated colony is cultured and RNA content of each colony is measured. The colony showing high content of RNA is selected and its morphological, physiological and cultural characteristics are identified. The isolated yeast forms creamy egg shape colony on YM plate and does not make spores. The range of temperature for growth is from 15 to 35°C. Under anaerobic condition it metabolizes D-glucose and D-cellobiose as carbon sources. On the other hand, D-xylose, L-rhamnose, cellobios, salicin, arbutin, glycerol, D-glucitol, citrate and ethanol can be metabolized at aerobic conditions. Nitrate, nitrite, L-lysine and creatine can be used as a nitrogen source at aerobic conditions. The yeast is cultured in YM medium and harvested at 10 OD and RNA content of cell is measured by orcinol method. The RNA content of Candida norvegica is 12-13% of cell mass.

    Abstract: PURPOSE: A novel lactobacillus sp. MT-1077 (KCTC 8903P) and a novel bacteriocin produced therefrom are provided. The bacteriocin has stability against broad range of pH, heat stability and antifungal activity and used as food preservation agent, biological fermentation regulator, and antifungal agent. CONSTITUTION: A lactobacillus MT-1077 is isolated from Kimchi. The method for purifying bacteriocin from lactobacillus MT-1077 comprises the steps of: incubating lactobacillus MT-1077 in MRS broth; precipitating the lactobacillus MT-1077 fermented culture broth by addition of ammonium hydrogen sulfate; passing the protein precipitates through the column packed with carboxymethyl sepharose CL-6B and eluting the adsorbed protein with 0.1M sodium chloride; passing the elutes through the column packed with phenyl sepharose CL-4B and eluting the adsorbed protein with 10% ammonium hydrogen sulfate solution; and purifying the elutes by HPLC
