Increasing production of betalactamic antibiotics in filamentous fungi by means of expression of the gene encoding cystationin-gamma-liase, where cg1A gene and enzyme have fully defined sequences given in the specification, is new. Increasing production of betalactamic antibiotics in filamentous fungi by means of expression of the gene encoding cystationin-gamma-liase, where cg1A gene and enzyme have fully defined sequences given in the specification comprising introducing the gene into Acremonium chrysogenum, thus obtaining transformants presenting an increased production of beta-lactams, or more concretely cephalosporins, in relation to the parental strains, without transformation, is new.
