Fig.4From: Purification and biofabrication of 5-aminolevulinic acid for photodynamic therapy against pathogens and cancer cellsTaguchi L9 experimental results for 5-ALA aPDT against the pathogen of Proteus hauseri. K1, K2 and K3 mean the average of killing rate for 3 levels of each parameter. The three levels of each factor: illuminating time (15, 30, 45 min); culture time (2, 3, 4 h); 5-ALA concentration (1%, 2%, 3%). R is the divergence which is indicated by red dotBack to article page
