Poly alkanoic acid monomers

The book is organized in several chapters and deals with the most important biopolymer classes like the different polysaccharides (starch, cellulose, chitin), lignin, proteins and (polyhydroxy alkanoates) as raw materials for bio-based plastics, as well as with materials derived from bio-based monomers like lipids, poly(lactic acid), polyesters, polyamides and polyolefines. Additional chapters on general topics - the market and availability of renewable raw materials, the importance of bio-based content and the aspect of biodegradability - provide important information related to all bio-based polymer classes. 

Deletion of the fabi gene can also be appUed in other malonyl-CoA based pathways, such as pathway 8, in order to increase the malonyl-CoA pool for 3-HP production. This malonyl-CoA mediated pathway was also used for the development of novel metabolic pathways for the production of P(3HB-co-3HP) from a structurally unrelated carbon source in Cupriavidus necator, in which malonyl-CoA reductase and the 3-HP-CoA synthetase domain of propionyl-CoA synthase from C. aurantiacus were employed [36]. Recombinant C. necator with malonyl-CoA mediated 3-HP synthetic activity could produce poly(3-hydroxybutyrate-co-3-hydroxypropionate) (P(3HB-co-3HP)), in which 3-HP monomer could be incorporated into copolymer up to 2.1 mol%, from fructose or even alkanoic acids [36].
