Abstract

Halomonas spp. are the well-studied platform organisms or chassis for next-generation industrial biotechnology (NGIB) due to their contamination-resistant nature combined with their fast growth property. Several Halomonas spp. have been studied regarding their genomic information and molecular engineering approaches. Halomonas spp., especially Halomonas bluephagenesis, have been engineered to produce various biopolyesters such as polyhydroxyalkanoates (PHA), proteins including surfactants and enzymes, small molecular compounds including amino acids and derivates, as well as organic acids. This paper reviews all the progress reported in the last 10 years regarding this robust microbial cell factory.

Key points

Halomonas spp. are robust chassis for low-cost production of chemicals

Genomic information of some Halomonas spp. has been revealed

Molecular tools and approaches for Halomonas spp. have been developed

Halomonas spp. are becoming more and more important for biotechnology
