To date, three main sources of microbial proteins derived from biomass fermentation have been evaluated in dogs and cats. These include Methylophilus methylotrophus (a methylotrophic bacterium), Methylococcus capsulatus (a methanotrophic bacterium), and microbial protein produced via the MicroHarvest fermentation platform, using natural bacterial strains from a variety of genera including Bacillus spp, Vibrio spp., and Geobacillus spp. This chapter discusses the different methods used to produce microbial biomass and the subsequent safety to workers, the nutritional profile of these bacteria, their palatability, digestibility and safety in cats and dogs, as well as observed health and immune responses. Additionally, the technical functionality of these proteins in wet and dry pet foods, along with consumer perceptions of these cultured proteins are examined. The chapter concludes with a summary of current limitations on the use of these proteins in pet food and provides a view on potential additional studies required to understand their mode of action and to unlock their full potential as sustainable complementary protein sources.},
