    Abstract: 본 발명은 병원성 및 비병원성 대장균에 공통으로 존재하는 편모형성유전자 hdfR에 대한 프라이머를 신규 제작하고, 이 프라이머를 이용한 중합효소연쇄반응(PCR) 기법으로 식수에서 대장균의 오염 여부를 조기에 확인할 수 있는 대장균 검출 방법에 관한 것이다. 본 발명에 따른 대장균 검출 방법으로 인하여 시료에 소량의 대장균이 존재하여도 증균 배양 단계를 거치지 않고 단지 소량의 DNA만을 가지고도 신속하고 정확하게 바로 대장균을 검출할 수 있다.

    Abstract: A detection method of E. coli in water samples using PCR is provided, thereby detecting infection of E. coli in drinking water at an early stage using a small amount of DNA of E. coli present in a sample, so that a seed culturing process can be eliminated. The detection method of E. coli in water samples comprises performing PCR using a primer for a flagellum forming gene hdfR, wherein the primer comprises a primer set consisting of a sense primer LysR-p1 having the nucleotide sequence of SEQ ID NO:1, AATCTAGTTGCTGTGCCAGT, and an antisense primer LysR-p2 having the nucleotide sequence of SEQ ID NO:2, TTGCTGGGATATTTCACTTT.

    Abstract: PURPOSE: A microorganism E. coli SB012 (KFCC 11203) sensitive to organic solvents and a method of preparation thereof are provided, thereby detecting toxicity more sensitively. CONSTITUTION: A microorganism E. coli SB012 (KFCC 11203) having improved sensitivity to organic solvents is prepared by modification or deletion of lipopolysaccharide in an extracellular membrane of E. coli SB01, wherein the modification or deletion of lipopolysaccharide in the extracellular membrane of E. coli SB01 is caused by treatment of E. coli SB01 with ethyl-methane-sulfonate(EMS), and repeatedly culturing the EMS-treated E. coli SB01 in a medium containing an antimicrobial agent and an organic solvent, wherein the antimicrobial agent is tetracycline and the organic solvent is para-xylene or bile acid salts.

    Abstract: PURPOSE: A recombinant plasmid containing luxCDABE, E. coli SB01 (KFCC 11176) transformed therewith, and the use thereof are provided, therefore the stability of the recombinant plasmid in E. coli can be increased to use it for the detection of toxicity. CONSTITUTION: The recombinant plasmid pBS1 contains a vector pKLJ12 containing luxCDABE derived from Photorhabdus luminescens. E. coli SB01 KFCC 11176 is produced by transforming E. coli DH5alpha with the recombinant plasmid pBS1. A method for detecting toxicity in a sample solution comprises culturing the transformed microorganism E. coli SB01 KFCC 11176 in the sample solution in a continuous fermenter, and analyzing the luminescence of the sample solution.
