Fuente: WIPO "tomato" The present disclosure is generally related to methods and compositions for producing heterologous globin proteins of interest in recombinant filamentous fungal cells. Certain embodiments are therefore, directed to compositions and methods for the production of globin proteins, recombinant filamentous fungal strains comprising enhanced globin protein productivity phenotypes, polynucleotides (e.g., expression constructs) encoding one or more globin proteins, industrial scale fermentation, globin protein recovery processes and the like.
