Different fermentation strategies were employed for the cultivation of a new poly(3-hydroxybutyrate)-accumulating thermophilic bacterium, Chelatococcus sp. strain MW10, with the aim of achieving high-cell-density (HCD) growth and high poly(3-hydroxybutyrate) [poly(3HB)] productivity. Enhanced cultiv...
