PHA’s (Poly Hydroxy Alkanoates)

What are PHA’s?

Polyhydroxyalkanoates (PHA’s) have been known by scientists for a very long time.x In fact, the simplest PHA, called P3HB, or sometimes just PHB, was discovered as early as 1926 by a French researcher, Maurice Lemoigne, in the course of his work with the bacterium Bacillus megaterium. At the time, little heed was paid to Lemoigne’s discovery, mainly because of  its perceived irrelevance: at the time, fossil fuels were inexpensive and abundant. But all that started changing when, in the 1970s, the oil crisis started and bio chemicals and plastics started to become viewed as a viable alternative to petroleum-based materials. It was around that time that microbiologists brought PHA to the attention of the industry.
