Protein-rich nutrient supplements and animal feed supplements derived from an anaerobic bacterial process are generated through a myriad of cell rupturing and protein fractionation/purification processes. Bacterial fermentation systems and methods of obtaining one or more protein-containing portions from a fermentation process using carbon monoxide-containing gaseous substrates are provided. The invention further provides compositions of protein-rich nutrient supplements with useful applications for intake by a variety of different animals and humans.

Microorganisms and bioprocesses are provided that convert gaseous substrates, such as renewable H.sub.2 and waste CO.sub.2 producer gas, or syngas into high-protein biomass that may be used directly for human nutrition, or as a nutrient for plants, fungi, or other microorganisms, or as a source of soil carbon, nitrogen, and other mineral nutrients. Renewable H.sub.2 used in the processes described herein may be generated by electrolysis using solar or wind power. Producer gas used in the processes described herein may be derived from sources that include gasification of waste feedstock and/or biomass residue, waste gas from industrial processes, or natural gas, biogas, or landfill gas.

Provided herein are color-fast edible compositions and methods of making the same. In some cases, the color-fast edible compositions comprise a comprising an exogenous protein component and a biomass comprising cells of a pigmented algae. The pigmented algal cells may be physically associated with the exogenous protein component such that the pigmented algal cells confer a pigmentation to the edible compositions and are substantially dissociable from the exogenous protein component. Further provided herein are food products (e.g., meat substitutes, fish or shellfish substitutes) comprising the color-fast edible compositions of the disclosure.
