Bio-induced overproduction of heterocycloanthracin-like bacteriocin in Lysinibacillus macroides by Aspergillus austroafricanus: optimization of medium conditions and evaluation of potential applications
The bacteriocin 'macroidin' is stable over a wide range of pH values and temperatures and has significant antimicrobial activity against Gram-positive food-borne and phytopathogenic strains of bacteria and moulds. Its antioxidant activities against DPPH and ABTS*<sup>+</sup> radicals are comparable to those of ascorbic acid, making this biomolecule a promising agent for biopreservation and phytopathogen control applications in the food and agricultural sectors.
