    Recursos alternativos para la identificación de Aspergillus spp. y la determinación de su potencialidad en la producción de aflatoxinas by Lozano Muñiz, Susana

    Published 2005
    “…The traditional identification process for these fungi is based on macro and micro morphological characteristics, but currently new immunological rapid methods and molecular techniques based on nucleotide sequence polymorphism from nuclear, ribosomal or mitochondrial DNA for studies at intra or inter specific level, have been developed. The objectives of this investigation were 1) identify A. flavus from other Aspergillus species that are important in health or industry, using amplification of intergenic ribosomal sequence and its electrophoretic analysis bye PAGE. 2) to subclone two intermediate enzymes before of the aflatoxin biosynthetic pathway on an E. coli system to obtain recombinant protein as a source for future studies on the potentiality of strains to produce aflatoxins. …”
