Abstract: The present disclosure provides a recombinant microorganism for producing PHBV, a method for preparing the same, and a method for producing PHBV using the microorganism. The present disclosure may provide a recombinant microorganism capable of producing PHBV, which is a biodegradable plastic material with superior physical properties, directly from an inexpensive single carbon source with high efficiency without supplementation of organic acid. The present disclosure can enhance the utilization of PHA, which is expensive and has limited physical properties, and can also provide a technology more effective for industrialization using an inexpensive single carbon source. The PHBV produced according to an exemplary embodiment of the present disclosure can be used not only for general-purpose inexpensive products such as ecofriendly packing materials but also as a high-value-added medical biopolymer.
