Upon direct pyrolysis of dry bacterial cells, the yield of II was 20-5% of the I in the cells. From the heteropolymer, 2-pentenoic acid and terminally unsatd. oligomers of polyhydroxyvalerate were ...

Bacteria, yeasts, or fungi can naturally synthesize fatty acids, isoprenoids, and polyalkanoates for energy storage. Although these compounds are mostly exploited in pharmaceutical, nutritional, and ...

Downgauging, lightweighting, and using fewer packaging materials are steps manufacturers have taken for years to cut costs where and when possible without compromising product integrity and efficacy.

The polyalkanoates have the potential to possibly overcome this gap, although they carry for the foreseeable future a tremendous increase in cost when compared to petroleum-based polymers. The ...

Downgauging, lightweighting, and using fewer packaging materials are steps manufacturers have taken for years to cut costs where and when possible without compromising product integrity and efficacy.

This is why all the important biodegradable polymers are polyesters: biobased ones such as polylactic acid (PLA), polyalkanoates (PHAs), and polybutylene succinate (PBS), as well as BASF’s ...

Analysis of the characteristic mass pe aks m/z=86 and 100 by PMSMS and PGCMS points to bacterial polyalkanoates in the mud fraction of the river sediments. These and other pyrolysis products show that ...
