Rational flux-tuning of Halomonas bluephagenesis for co-production of bioplastic PHB and ectoine

Nature Communications, 2020
Ectoine, a compatible solute synthesized by many halophiles for hypersalinity resistance, has been successfully produced by metabolically engineered Halomonas bluephagenesis, which is a bioplastic poly(3-hydroxybutyrate) producer allowing open unsterile ...

PLA/PHB Blends: Biocompatibilizer Effects [PDF]

Polymers, 2019
The purpose of this work was to formulate a fully bio-based blend with superior properties, based on two immiscible polymers: polylactic acid (PLA) and poly-hydroxy butyrate (PHB). To improve the miscibility between the polymeric phases, two different kinds of compatibilizers with a different chemical structure were used, namely, an ethylene oxide ...

The Screening of PHB Secretion Strain of PHB Synthesis [PDF]

Proceedings of the 2nd Annual International Conference on Advanced Material Engineering (AME 2016), 2016
PHB is similar with non degradable plastic which is widely used in most properties. It is supposed to be an excellent substitute of traditional petrochemical plastics because of its biodegradable character. However, the production cost of PHB is much higher than that of traditional plastic.
