Colorectal cancer is a major global health concern, with a strong link to processed meat consumption and the formation of carcinogenic compounds. This study explores the potential of selected probiotic strains, including Lactobacillus plantarum, Lactobacillus casei, and Bifidobacterium bifidum, in degrading a specific carcinogen called 4-Nitroquinoline-1-Oxide (4-NQO). The research investigates the effect of 4-NQO on the growth of the test organisms individually and as a consortium, as well as the degradation of 4-NQO by the test organisms. The study employs culture methods and High-Performance Liquid Chromatography (HPLC) to analyze the growth patterns and degradation of 4-NQO over specific time intervals. The results show minimal impact of 4-NQO on the growth of Lactobacillus casei, while Lactobacillus plantarum demonstrates a slight decline in growth. Bifidobacterium bifidum exhibits consistent growth patterns in the presence of 4-NQO, indicating resilience to the carcinogen. Additionally, the consortium of cultures shows similar trends to the individual strains. These findings also contribute to understanding the potential role of selected probiotic species in the degradation of 4-NQO and its implications for cancer mitigation.
