Abstract

In this study, we developed Rapid Enrichment Broth for Vibrio parahaemolyticus (REB-V), a broth capable enriching V. parahaemolyticus from 100 CFU/mL to 106 CFU/mL within 6 hours, which greatly facilitates the rapid detection of V. parahaemolyticus. Using a modified Gompertz model and response surface methodology, we optimized supplement sources to rapidly enrich V. parahaemolyticus. The addition of 0.003 g/10 mL of D-(+)-mannose, 0.002 g/10 mL of L-valine, and 0.002 g/10 mL of magnesium sulfate to 2% (w/v) NaCl BPW was the most effective combination of V. parahaemolyticus enrichment. Optimal V. parahaemolyticus culture conditions using REB-V were at pH 7.84 and 37℃. To confirm REB-V culture efficiency compared to 2% (w/v) NaCl BPW, we assessed the amount of enrichment achieved in 7 hours in each medium and extracted DNA samples from each culture every hour. Real-time PCR was performed using the extracted DNA to verify the applicability of this REB-V culture method to molecular diagnosis. V. parahaemolyticus was enriched to 5.452±0.151 Log CFU/mL in 2% (w/v) NaCl BPW in 7 hours, while in REB-V, it reached 7.831±0.323 Log CFU/mL. This confirmed that REB-V enriched V. parahaemolyticus to more than 106 CFU/mL within 6 hours. The enrichment rate of REB-V was faster than that of 2% (w/v) NaCl BPW, and the amount of enrichment within the same time was greater than that of 2% (w/v) NaCl BPW, indicating that REB-V exhibits excellent enrichment efficiency.

본 논문은 적은 농도로 존재하는 Vibrio parahaemolyticus를 6시간이내에 106 CFU/mL까지 신속하게 배양가능한 배지인 Rapid Enrichment Broth for V. parahaemolyticus(REB-V)를 개발하여 V. parahaemolyticus를 신속하게 검출할 수 있도록 하였다. Modified Gompertz model과 RSM를 활용하여 V. parahaemolyticus를 신속하게 증균할 수 있도록 첨가 성분을 최적화하였다. 그 결과 2%(w/v) NaCl BPW에 D-(+)-mannose 0.3 g/L, L-valine 0.2 g/L, magnesium sulfate 0.2 g/L를 첨가하였을 때 V. parahaemolyticus의 증균량이 최대였다. REB-V의 배양조건을 pH 7.84와 37℃으로 최적화하였으며, 2%(w/v) NaCl BPW와 비교하여 REB-V의 증균 효율을 확인하기 위해 7시간 증균을 통해 증균량을 평가하였다. 또한 매시간마다 배양액에서 DNA를 추출하였고, 추출한 DNA로 real-time PCR을 수행하여 REB-V의 분자진단법 적용가능성을 확인하였다. 그 결과 7시간 동안 2%(w/v) NaCl BPW에서 V. parahaemolyticus는 5.452±0.151 Log CFU/mL까지 증균되었고, REB-V에서는 7.831±0.323 Log CFU/mL의 V. parahaemolyticus가 증균되었다. 최종적으로 REB-V에서 6시간 이내에 106 CFU/mL 이상으로 증균된 것을 확인하였고, REB-V의 증균속도가 2%(w/v) NaCl BPW보다 빠르고 같은 시간 내의 증균량이 2%(w/v) NaCl BPW보다 많았음을 통해 REB-V의 증균효율이 우수한 것으로 확인되었다.
