Studies on the Yeasts Isolated from Kimchi
The Korean Journal of Microbiology, volume 16, issue 1, 1978, Pages 1~10
In order to isolate and identify of the yeasts in Chinese cabbage Kimchi, was propared and fermented by traditional methods. 40 strains of the yeast were isolated from the Kimchi juice. As the results of the serial experiemnts on morphological, cultural and physiological properties, according to the methods of Lodder, Irzuka, Barnett and Hasegocwa, 13 species of S genera were identified as the followings ; Brettanomyces claussenii, Candida bogoriensis, C.cacaoi, C.guilliermondii, Citeromyces matritensis, Kluyveromyces vaeronae, Pichia membranaefacience, Rhodtorula glutinis, Saccharomyces bayanus, S, cerevisiae, S. pretoriensis, S. italicus, and Torulopsis salmanticensis.
Studies on the Microbial Pigment(II)
The Korean Journal of Microbiology, volume 16, issue 1, 1978, Pages 11~15
Glucose and galactose were the inhibitors of pigmentation of Serrratia marcescens. Other sugars, however, even the fructose which is the structural isomer of glucose and galactose did not affect to pigmentatioin. The yield of pigmentation was descreased when the glucose was added to culture medium. And it was known to that the antibiotics was roled as the inhibitors of pigmentation. The limit concentration of the inhibitors were as followings :rifampicin,
. Addition of rifampicin
at 6 hrs cultures inhibited the formation of pigment completely.
Studies on the Microbial Pigment(III) -Tho Effect of Tyrosine-
The Korean Journal of Microbiology, volume 16, issue 1, 1978, Pages 16~20
Of the eight single acids, only the tyrosine induced the pigmentation. By dint of tracer works of labelled tyrosine with wild type and two mutants, 82% of carboxyl-tyrosine was incroporated, into the primary cellular metabolite and 19% of this was inverted to the red pigment. And 11% was incorporated into the red pigment directly.
Effects of Carbon Sources and Other Process Variables in Fed-Batch Fermentation of Penicillin
The Korean Journal of Microbiology, volume 16, issue 1, 1978, Pages 21~29
In the fed-batch fermentation of penicillin specific uptake rates of carbon source and ammonia nitrogen, and specific production rate of penicillin as the most important process variables were evaluated over the fermentation course and their effects on the productivity studied. As the results, glucose and lactose each as a major carbon source showed the following values, respectively ; the specific uptake rates of 47-93 mg hexose per gm-DCW per he and 37-44 mg hexose per gm-DCW per hr, the specific uptake rates of 4.6-6.8 mg
per gm-DCW per hr, and 1.2 mg
per gm-DCW per he and the specific production rates of 32-42 arbitrary unit per gm-DCW per hr and 46-50 arbitrary unit per gm-DCW per hr. The productivity of penicillin could be improved by controlling the feed rates of glucose and ammonia nitrogen to meet the uptake rates.
Immunological Identification of Thiobacillus ferro-oxidans and Thiobacillus thiooxidans
The Korean Journal of Microbiology, volume 16, issue 1, 1978, Pages 30~40
Detergent soluble fractions were obtained from T. ferrooxidans ATCC 13598 and the T. thiooxidans ATCC 8085 which were treated with 3% of Tween 20. The detergent soluble antigen(crude antigen) fractions of the T.ferrooxidans and the T.thiooxidans were subjected to hydroxyapatite. In the case of T.thiooxidans, further purification was carried out on the DEAE-cellulose column chromatography. The antigen fractions, such as the hydroxyapatite peak-1(Tf, HA-1) and peak-2 from T.ferrooxidans(Tf. HA-2) and hydroxyapatite peak-1(Tt, HA-1), DEAE-cellulose peak-1(Tt, DP-1) and peak-2(Tt, DP-2) from T. thiooxidans wre compared each other with the homologous and the heterologous and the heterologous antisera against to the Thiobacillus species. The hydroxyapatite peak-2 fraction from the T.ferrooxidans(Tf, HA-2) and DEAE-cellulose peak-2 fraction from the T.thiooxidans(Tt, DP-2) were represented the type-specific immuno-reactivities between the T.ferrooxidans and the T.thiooxidans on the several sets of double gel diffusioin analysis. The type-specific antigen fractions from both of the baceteria were mainly composed of protein with entierly different electrophoretic mobility on the SDS-polyacrylamide gel electrophoresis. However, the PAS positive banding patterns on the electrophorogram showed wide range of common antigenic properties in the T. ferrooxidans and the T.thiooxidans, respectively.
