    초록

    The efficient manufacture of fermented dairy products on an industrial scale requires a supply of reliable starter cultures with properties suited to desired product specifications. These cultures must be backed by relevant research and development activities. This article describes the issues involved in establishing a centre to provide starter culture R & D for a group of independent cheese manufacturing companies, and discusses a strategic approach to the management of starter cultures.

  2. [국내논문]   Overproduction of Escherichia coli D-Xylose Isomerase Using ${\lambda}P_L$ Promoter   피인용횟수: 2

    초록

    In order to overproduce D-xylose isomerase, the Escherichia coli D-xylose isomerase (D-xylose ketol-isomerase, EC 5.3.1.5) gene (xylA) was fused to ${\lambda}P_{L}$ promoter. The promoterless xylA gene containing the ribosome binding site and coding region for D-xylose isomerase was cloned into a site 0.3 kb downstream from the ${\lambda}P_{L}$ promoter on a high copy number plasmid. An octameric XbaI linker containing TAG amber codon was inserted between 33rd codon of ${\lambda}N$ and the promoterless xylA gene. The resulting recombinant plasmid (designated as pPX152) was transformed into E. coli M5248 carrying a single copy of the temperature sensitive ${\lambda}cI857$ gene on its chromosomal DNA. When temperature-induced, the transformants produced 15 times as much D-xylose isomerase as that of D-xylose-induced parent strain. The amount of overproduced D-xylose isomerase was found to be about 60% of total protein in cell-free extracts.

  3. [국내논문]   Role of Siderophores in Biocontrol of Fusarium solani and Enhanced Growth Response of Bean by Pseudomonas fluorescens GL20   피인용횟수: 2

    Lim, Ho-Seong (Department of Applied Microbiology, Yeungnam University ) , Kim, Sang-Dal (Department of Applied Microbiology, Yeungnam University)
    Journal of microbiology and biotechnology v.7 no.1 ,pp. 13 - 20 , 1997 , 1017-7825 ,

    초록

    Plant growth-promoting Psudomonas fluorescens GL20 was isolated from a ginseng rhizosphere on chrome azurol Sagar. P. fluorescens GL20 produced a large amount of hydoxamate siderophore in an iron-deficient medium. The siderophore showed significantly high specific activity of 20.2 unit. Using an in vitro antifungal test, P. fluorescens GL20 considerably suppressed growth of phytopathogenic fungus Fusarium solani, inhibiting spore germination and germ tube elongation. In pot trials of kidney beans with P. fluorescens GL20, disease incidence was remarkably reduced up to $68{\%}$ compared with that of F. solani alone, and plant growth was also increased nearly 1.6 fold as compared to that of the untreated control, promoting elongation and development of the roots. These results indicate that the plant growth-promoting activity of P. fluorescens GL20 can play an important role in biological control of soil-borne plant disease in a rhizosphere, enhancing the growth of plants.

  5. [국내논문]   Properties of the Fusants of Lactobacillus acidophilus 88 and Lactobacillus casei subsp. casei KCTC 1121

    Journal of microbiology and biotechnology v.7 no.1 ,pp. 25 - 31 , 1997 , 1017-7825 ,

    초록

    Protoplast fusion between L. casei KCTC 1121 and L. acidophilus 88 was attempted to obtain improved strains. The fusants produced a bacteriocin against indicator strains, making a smaller inhibition zone compared to that of L. acidophilus 88. After culturing for 2 months on selective medium, the selected fusants were still stable without segregation. Fusants showed higher lipase activity compared to those of the two parent strains. Fusant No.4, 11, and 15 exhibited excellent lactic acid productivity. Fusant No.4 and 15 exhibited improved proteolysis ability compared to the two parent strains. Whereas L. casei possessed both ${\beta}-galactosidase$ and $phospho-{\beta}-galactosidase$ activities, and L. acidophilus 88 had only ${\beta}-galactosidase$ activity, the fusants had both the intermediate enzyme activities. Cell size of the fusants was greater than that of the parents.

  7. [국내논문]   Purification and Partial Characterization of Thermostable Carboxyl Esterase from Bacillus stearothermophilus L1   피인용횟수: 1

    초록

    A bacterial strain L1 producing a thermostable esterase was isolated from soil taken near a hot spring and identified as Bacillus stearothermophilus by its microbiological properties. The isolated thermostable esterase was purified by ammonium sulfate fractionation, ion .exchange and hydrophobic interaction chromatographies. The molecular weight of the purified enzyme was estimated to be 50,000 by SDS-PAGE. Its optimum temperature and pH for hydrolytic activity against PNP caprylate were $85^{\circ}C$ and 9.0, respectively. The purified enzyme was stable up to $70^{\circ}C$ and at a broad pH range of 4.0-11.5 in the presence of bovine serum albumin. The enzyme was inhibited by phenylmethylsulfonyl fluoride and diethyl p-nitrophenyl phosphate, indicating the enzyme is a serine esterase. The enzyme obeyed Michaelis-Menten kinetics in the hydrolysis of PNPEs and had maximum activity for PNP caproate ( $C_6$ ) among PNPEs ( $C_2-C_12$ ) tested.

  8. [국내논문]   Degradation of Chlorophenols and Phenol Mixtures by Cooperative Activities of Chlorophenol-degrading Strains   피인용횟수: 2

    초록

    Three strains capable of degrading a chlorophenol were isolated by selective enrichment from soils contaminated with industrial wastewater. A Pseudomonas solanacearum TCP114 could use 2,4,6-trichlorophenol (TCP) as sole carbon and energy source, while two strains of Pseudomonas testosteroni CPW301 and Arthrobacter ureafaciens CPR706 could use 4-CP. All isolates also grew well on phenol. The degradation of one component by a pure strain was strongly affected by the presence of other compounds in the medium, CPW301 and CPR706 entirely lost the ability to degrade 4-CP and phenol in the presence of TCP. TCP114 also lost the ability to degrade phenol when 4-CP was added to the culture medium. These restrictions on the degradability could be overcome by employing defined mixed cultures (TCP114 and one strain of 4-CP degrading strains). All three components were successfully degraded by defined mixed cultures through their cooperative activities. It was also demonstrated that defined mixed cultures could be immobilized by using calcium alginate for the semi-continuous degradation of the three component mixture. Immobilization could not only accelerate the degradation rate, but also allowed the reuse of the cell mass several times without loss of the cells' degrading capabilities.

  10. [국내논문]   Immunostimulating Activity of Polysaccharides from Mycelia of Phellinus linteus Grown under Different Culture Conditions   피인용횟수: 14

    초록

    Polysaccharides were extracted from mycelia of Phellinus linteus grown under different culture conditions. The in vitro immunostimulating activity was measured by plaque-forming cell (PFC) assay. The activity of the polysaccharides was different from that of mycelia from which was extracted. The number of PFC's ranged from 40 to 600 depending on the media. When P. linteus was cultured on a medium with mannose or starch as a sole carbon source, the fungus produced polysaccharide with the highest activity of 960 PFC. Activity was therefore increased by $50%$ compared with polysaccharide which was extracted from mycelia grown on medium with glucose. pH had little effect on the change in activity. All polysaccharides on media with different pH stimulated about 600 PFC. These results suggest that activity could be increased by polysaccharide modification through changes in physiological conditions.
