2.10 Conclusion
The biopolymers contain eight groups based on their chemical structure. A ninth group could be added to include the monomers that are produced naturally and polymerized chemically such as polylactic acid. The polymeric forms of the inorganic structures are in need of more investigation. There are some unique criteria for biopolymers because they are derived from nature. They are degradable, bioavailable, compatible, renewable, safe, etc., so they are “green”. They are the main income resources for a number of countries. Their applications are diverse. Some have not yet been commercialize due to petroleum oil-based synthetic polymers. Some species of the biopolymer have attracted attention in different times. For example, polyhydroxyalkanoates attract attention after the oil crises in 1973. Being produced by different types of biological cells their control through biochemical engineering or through different molecular tools enabled better management of their production in their mother wild type host cells or in foreigner cells. We should keep the different schools of biopolymer active. The ones which not being focused on today might be in great demand in the future.
