Título: | Enhancing laccase production by white-rot fungus Funalia floccosa LPSC 232 in co-culture with Penicillium commune GHAIE86 |

N.; García-Romera, Inmaculada CSIC; Sampedro, Inmaculada CSIC ORCID | Fecha de publicación: | 2019 | Editor: | Springer Nature | Citación: | Folia Microbiologica 64: 91- 99 (2019) | Resumen: | To obtain enzymatic preparations with higher laccase activity levels from Funalia floccosa LPSC 232, available for use in several applications, co-cultures with six filamentous microfungi were tested. A laccase non-producing soil fungus, identified as Penicillium commune GHAIE86, showed an outstanding ability to increase laccase activity (3-fold as compared to that for monoculture) when inoculated in 6-day-old F. floccosa cultures. Maximum laccase production with the F. floccosa and P. commune co-culture reached 60 U/mL, or twice that induced by chemical treatments alone. Our study demonstrated that co-culture with soil fungi might be a promising method for improving laccase production in F. floccosa. Although the enhancement of laccase activity was a function of P. commune inoculation time, two laccase isoenzymes produced by F. floccosa remained unchanged when strains were co-cultured. These data are compatible with the potential of F. floccosa in agricultural applications in soil, whose enzyme machinery could be activated by soil fungi such as P. commune. | Versión del editor: | https://link.springer.com/article/10.1007%2Fs12223-018-0635-y | URI: | http://hdl.handle.net/10261/181378 | DOI: | 10.1007/s12223-018-0635-y | Identificadores: | doi: 10.1007/s12223-018-0635-y issn: 1874-9356 |
