Hiện nay, việc định danh một số loài Bifidobacterium spp. trong thực phẩm chức năng và bổ sung bằng phương pháp nuôi cấy vi sinh truyền thống còn hạn chế. Phương pháp PCR được đề xuất để nghiên cứu triển khai định danh một số loài Bifidobacterium spp. trong thực phẩm chức năng và thực phẩm bổ sung.

Nghiên cứu nhằm mục tiêu khảo sát các thông số của qui trình PCR để phát hiện 4 loài Bifidobacterium trong thực phẩm chức năng và thực phẩm bổ sung.

Khảo sát quy trình tách chiết; khảo sát độ đặc hiệu của mồi; tối ưu hóa điều kiện phản ứng PCR; khảo sát mức phát hiện LOD50 ; ứng dụng quy trình phân tích một số mẫu thực tế.

Kết quả nghiên cứu cho thấy, chúng tôi đã lựa chọn được 5 cặp mồi đặc hiệu trong đó có 4 cặp mồi phát hiện 4 loài Bifidobacterium bao gồm B. animalis, B. breve, B. bifidum, B. lactis LOD50 của các qui trình PCR để phát hiện các loài Bifidobacterium spp. đều ở mức thấp (dưới 2 CFU/g) bao gồm: mẫu thực phẩm chức năng từ 1 CFU/g (B. bifidum, B. lactis) đến 1,4 CFU/g (B. breve, B. animalis); từ 1 CFU/g (B. animalis, B. breve) đến 1,3 CFU/g (B. lactis, B. bifidum) trong nền mẫu thực phẩm bổ sung. Phương pháp có độ chọn lọc tốt, chỉ phát hiện đặc hiệu trên chủng mục tiêu. Quy trình PCR này có thể áp dụng để phát hiện 4 loài vi khuẩn Bifidobacterium trong thực phẩm chức năng và thực phẩm bổ sung.
