PHA from coal ?

摘要

Low rank coal represents a cheap and in large quantities available carbon source with a complex chemical structure. This heterogeneous structure is a burden for further degradation and to obtain well-defined products. Bacteria are able to produce polyesters of hydroxyalkanoic acids (PHA) as storage compounds for carbon and energy. PHA exhibit several interesting properties like insolubility in water and a highly homogeneous chemical structure. Our aim is the selection of bacteria, which are able to convert the heterogeneous carbon sources from liquefied coal to useful and homogeneous PHA or into other interesting products.
