QPS assesses safety of microorganisms in food additives and related products. QPS differentiates safe from potentially risky microorganisms. Process covers safety concerns for humans, animals and environment
Archaea are unicellular prokaryotes found in extreme environments. They share characteristics with bacteria but lack peptidoglycan. Cell walls contain pseudopeptidoglycan instead of peptidoglycan. Cell membranes use ether linkages instead of ester linkages
Founded in Canada at end of 19th century. Specializes in microorganisms and their derivatives. Global privately held company with 300 strong R&D scientists
Aerobes can survive and grow in oxygenated environments. Obligate aerobes require oxygen for growth and energy production. Facultative anaerobes use oxygen when available but can survive anaerobically. Microaerophiles require oxygen but are harmed by atmospheric oxygen. Aerotolerant anaerobes don't use oxygen but aren't harmed by it
Rotifers are microscopic pseudocoelomate animals first described by Harris in 1696. Most species are 0.1-0.5 mm long, some freshwater, some saltwater. About 2,200 species described, divided into three classes: Seisonidea, Bdelloidea, Monogononta
Euglena is a single-celled organism found in water, requiring microscope. Can be both plant-like (photosynthetic) and animal-like (heterotrophic). Contains chloroplasts for photosynthesis and paramylon storage. Has flagella for movement and red stigma for light detection
