Sobre IBD

Uno dei modi per ridurre i costi di produzione dei biosurfattanti è quello di aggiungere valore alla biomassa e all’estratto del microrganismo produttore. Ad esempio, la produzione in vitro di tensioattivi ha una bassa resa e prevede la coltivazione di Bacillus subtilis in terreni sintetici utilizzando substrati costosi. Durante la crescita, la surfactina e altri lipopeptidi ed enzimi importanti per l’industria farmaceutica, l’industria alimentare e la produzione di etanolo, come l’alfa-amilasi, la lipasi e la cellulasi, vengono prodotti e secreti nel terreno di coltura. Al termine della crescita microbica, l’estratto viene separato dalla biomassa mediante centrifugazione. Questa biomassa, che altrimenti verrebbe scartata, è una fonte di proteine e lipidi, con potenziali applicazioni per la sintesi di altri tensioattivi, e può essere utilizzata anche per la decontaminazione ambientale. L’obiettivo principale di questo lavoro è presentare alternative per ridurre i costi di produzione delle tensioattività.
