Introduction

Natural plant materials as the main raw material, the use of bio-fermentation engineering technology to produce polyhydroxyalkanoates (polyhydroxyalkanoates, Jane Said PHA), by changing the bacteria, carbon source and cultured during controlled conditions, can be prepared PHA different structure to meet the various functions need. PHA is a general term for a class of materials, the structure of the formula can be expressed as. Wherein. m = 1, 2 or 3 under, in most cases, m = 1, i.e., 3-hydroxy-alkanoates (3-HA); when R = methyl, poly-3-hydroxybutyrate of PHA Butyrate (PHB); when R = ethyl group, a poly-3-hydroxy valerate (PHV); when R = propyl, poly-3-hydroxy caproate (PHH). Have been found in the largest R group is nonyl, namely monomer is 3-hydroxy-dodecanoic acid. m = 2, unbranched, PHA is poly-4-hydroxyphenyl Butyrate (P-4HB), at the same time, control of the culture conditions and carbon sources, the bacteria can produce a copolymer of two or more monomers such as poly - 3-hydroxy - butyrate - valerate (PHBV), poly-3-hydroxybutyrate - hexanoate (PHBH), poly-3-hydroxybutyrate-3-hydroxyvalerate [P (3, 4HB)], PHBVH (poly-3-hydroxy-3-hydroxy-pentanoic acid 3-hydroxy hexanoate) and the like. Biomanufacturing polyhydroxyalkanoates

1 Scope

This standard specifies requirements for polyhydroxyalkanoates (polyhydroxyalkanoates, PHA) products, test methods, inspection rules, marking Chi, packaging, transport and storage. This standard applies to the use of PHA family microbial fermentation production of poly-3-hydroxybutyrate (PHB), poly-3-hydroxy - butyric acid - Valerate (PHBV) (HV≤12%), poly -3-hydroxybutyrate - hexanoate (PHBH) (HH≤15%), poly-3-hydroxy-4-hydroxy-butyric acid Ester [P (3,4HB)] (4HB≤15%).
