Autotrophic hydrogen-oxidizing bacteria (HOB) have received increasing attention as a promising source of microbial protein (MP). However, most the studies were conducted at relatively low ammonium concentrations (?1 g N–NH 4 + /L). This study investigated effect high and various nitrogen forms on growth Cupriavidus necator 335 for MP production. The cell was slightly inhibited 2 /L completely ...

The waste fish oil obtained from Baltic sprat in the production of canned sprats was studied as a sole carbon substrate for PHA synthesis by wild-type strain Cupriavidus necator B-10646. Sprat contained set fatty acids with chain length C14 to C24, saturation factor 0.63, and provided bacterial growth synthesis. Bacteria metabolized unevenly utilizing polyenoic not using monoenoic saturated aci...

The production of poly(hydroxylalkanoates) (PHA) is limited by the high cost feedstock since various biomass wastes look attractive as possible sources for polymer production. originality this present study in biotransformation mixed Chlorella-based substrates into PHAs. synthetic potential Cupriavidus necator B8619 cells was studied during bioconversion algae mixtures with spent immobilized my...

The study addresses the growth of new wild-type strain Cupriavidus necator IBP/SFU-1 and synthesis poly(3-hydroxybutyrate-co-4-hydroxybutyrate) (P(3HB-co-4HB) on media containing fructose three different precursors 4HB (ε-caprolactone 1,4-butanediol 1,6-hexanediol). It was found that ε-caprolactone is best precursor for P(3HB-co-4HB) copolymers. By varying concentration number doses added into ...
