What is The Preservative Propionic Acid Differentially Affects Survival of Conidia and Germ Tubes of Feed Spoilage Fungi about?
Propionic acid is widely used as a preservative in (poultry) feed. In this study we have isolated and identified fungal strains from nine samples poultry feed originating from different countries. The majority of the strains were Aspergilli with a eurotium-morph, such as Aspergillus proliferans and A. chevalieri. These and three other species were selected and tested for their sensitivity towards the feed preservative propionic acid, among them Penicillium lanosocoeruleum. The determined MIC values of 6.1–31 mM of these poultry feed specific fungi were well in the range as described in literature. Propionic acid (at 31 mM) damages conidia (spores) in a species dependent fashion after a 24-hour-treatment. The majority of the conidia (over 70%) of P. lanosocoeruleum germinated within 60 h on agar medium, while 50 and 80% of the A. chevalieri and A. proliferans conidia did not, respectively. Dependent on the species, cell damage was visible after incubation with propionic acid. Germ tubes of P. lanosocoeruleum in a biofilm showed extensive (85%) cell death after a 30 min treatment with propionic acid and slightly lower sensitivity was observed with A. proliferans (62% cell death).
