title: Bioprocess Intensification for Production of Novel Marine Bacterial Antibiotics Through Bioreactor Operation and Design.
abstract: : There is a lack of research into bioreactor engineering and fermentation protocol design in the field of marine bacterial antibiotic production. Most production strategies are carried out at the shake-flask level and lack a mechanistic understanding of the antibiotic production process, offering poor prospects for successful scale-up. This review shows that data need to be collated on media and physical optima differences between the trophophase and idiophase, along with investigations into the control mechanisms for biosynthesis, to allow implementation of novel fermentation protocols. Immobilization may play a part in bioprocess intensification of marine bacterial antibiotic production, through again this area is understudied. Similarly, mass transfer and shear stress data of fermentations are needed to provide the bioreactor design requirements to intensify antibiotic biosynthesis, with process scale-up in mind. The application of bioprocess intensification methods to the production of antibiotics (and other metabolites) from marine microbes will become an important strategy for improving supply of natural products, in order to assess their suitability as chemotherapeutic drugs.
