| Résumé : |
The utility of a high-throughput, spectrophotometric assay in screening over 23 enzyme and peptide-based additives against bacterial coating spoilage agents was evaluated. Candidate additives were then evaluated using ASTM D2574 for in-can coating spoilage challenges, and additives that may be used to substitute for traditional biocides were identified that eliminated recoverable bacterial growth. |

- Fig. 1. Effects of various bio-based additives, alone and in combination, on the growth of a mixture in equal of A. faecalis, B. cereus, E. aerogenes, p. aeruginosa, p. fluorescens, and P. putida
- Fig. 2. Effects of various bio-based additives, alone and in combination with traditional chemical-based biocides, on the growth of a mixture in equal parts of A. faecalis, B. cereus, E. aerogenes, p. aeruginosa, p. fluorescens, and P. putida
- Fig. 3. Comparison of colony types present on plates from paint samples that scored 4 on day 7. Comparison of day 7 plates from the control acrylic latex samples (A) and acrylic latex + 0.05 mg/mL glucose oxidase + 2 mg/mL dextrose (B) shows that the paint with bio-based additive, though scorling 4 according to the ASTM guidelines, had at least one fewer colony type compared to the control |
