Provided is food component comprising cells of at least one bacterium, said cells comprising a crude protein concentration of at least 60 wt % of a total dry weight of said cells and nucleic acid at a concentration of less than about 5 wt % of a total dry weight of said cells, wherein at least 50% of a total number of said cells are dead cells. Further provided are food and beverages comprising such food components and methods of manufacture thereof.

Provided herein is a composition comprising a solid product of a co-culture of bacteria and fungi, comprising at least 5% protein by dry weight and at least 5% fiber by dry weight. Further provided is a food article formed from a pellicle comprising a solid product of a co-culture of bacteria and fungi, which comprises at least 5% fungal protein by dry weight and at least 5% fiber by dry weight, and which is formed into a shape by cutting or molding. Further provided is a method of making such products by co-culturing bacteria and fungi to form a pellicle, and harvesting and shaping the pellicle. Further provided is a system that optimizes growth and production of a co-culture of bacteria and fungi (co-culture of microorganism) that includes a housing unit that includes stacked trays.

The present disclosure provides food compositions for humans comprising a Methylococcus capsulatus protein isolate or whole cell product, wherein the Methylococcus capsulatus protein isolate or whole cell product is composed of at least 70% crude protein; has a protein digestibility corrected amino acid score (PDCAAS) of at least 0.9; and has a .sup.13C of about 70 to about 30. Methylococcus capsulatus protein isolates or whole cell products provided herein are useful for the manufacture of meat substitutes as well as other food compositions, such as protein bars, nutritional beverages, protein supplement powders, frozen non-dairy desserts, and baked goods.

Methods of production of edible filamentous fungal biomat formulations are provided as standalone protein sources and/or protein ingredients in foodstuffs as well as a one-time use or repeated use self-contained biomat reactor comprising a container with at least one compartment and placed within the compartment(s), a feedstock, a fungal inoculum, a gas-permeable membrane, and optionally a liquid nutrient medium.

An edible meat substitute product includes a fibrous mycelium mass in a range of 10 wt % to 100 wt %. The fibrous mycelium mass has a protein content greater than 40 wt % of a dry mass of the fibrous mycelium mass. The edible meat substitute product includes a water content in a range of 0 w % to 90 wt %.

A method of growing fungal mycelium and forming edible food products includes growing fungal cells in a growth media such that the fungal cells produce mycelium. The growth media includes a sugar, a nitrogen-containing compound, and a phosphate-containing compound. The mycelium is separated from the growth media. The mycelium is concentrated to obtain a fibrous mycelium mass having a protein content of greater than 40 wt % of a dry mass of the mycelium. Food additives can be added to the fibrous mycelium mass to produce a biomass. The biomass can be formed into an edible food product. The biomass can be formed into an edible meat substitute product.

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.
