Breast cancers are usually treated with surgery and radiation excretes adverse effects. Azurin, a potent anticancer redox protein secreted by Pseudomonas aeruginosa (P. aeruginosa) species has been reported to have activity against breast cancer cell lines; this had prompted researchers to search for novel methods to enhance this protein's production. Researchers previously have reported on the synthesis of blue copper protein azurin from different microbial sources specifically from P. aeruginosa. Our investigation used customized methods to focus on synthesizing azurin from different strains of P. aeruginosa with apparent homogeneity. We screened the growth of different P. aeruginosa strains (1934, 741, 2453, and 1942) for the synthesis of azurin and for enhanced azurin production. We exposed azurin properties using matrix-assisted laser desorption/ionization, sodium dodecyl sulfate polyacrylamide gel electrophoresis and Fourier transform infrared spectroscopy. Additional studies of possible molecular mechanisms and reactive oxygen species (ROS) generation of P. aeruginosa 2453 secreted azurin are needed. We examined which strain among P. aeruginosa strains 1934, 741, 2453, and 1942 best enhanced azurin production. Our current study also revealed which strain of the four had the strongest antiproliferative effect of azurin. P. aeruginosa MTCC (Microbial Type culture collection) 2453 was the strain that secreted the most azurin and showed remarkable apoptosis in breast carcinoma cells like T- 47D and ZR-75-1. This study demonstrates customized methods to synthesize azurin from different strains of P. aeruginosa with apparent homogeneity and their apoptotic effects on breast carcinoma cells with possible molecular mechanisms and ROS.
