Abstract
Shaped articles can be made by extruding, or injection moulding, a composition containing at least 50% by weight of dried cells of a micro-organism containing a .beta.-hydroxybutyrate polymer. In order to make the composition melt processable the cells are subjected to a cell wall breakage step before or after drying and, if necessary, are mixed with an extracted .beta.-hydroxybutyrate polymer.
