<unk> s can be used for different industrial and pharmaceutical purposes. Medical E. coli strains are the main source of medical<unk> . Branded formulations (with different chemical and pharmacological properties) available in 1998 include<unk>  Medac, Ciderolase, and Oncaspar. (Crasnitin has been discontinued.) Spectrila is a recombinant E. coli<unk> .<unk>  produced by Dickeya dadantii (formerly called Erwinia chrysanthemi) instead is known as crisantaspase (BAN), and is available in the United Kingdom under the brand name Erwinase. One of the E. coli<unk> s marketed under the brand name Elspar for the treatment of acute lymphoblastic leukemia (ALL) is also used in some mast cell tumor protocols. On 30 June 2021, the U.S. Food and Drug Administration (FDA) approved<unk>  erwinia chrysanthemi (recombinant)-rywn) as a component of a multi-agent chemotherapeutic regimen for the treatment of acute lymphoblastic leukemia (ALL) and lymphoblastic lymphoma (LBL) in people aged one month or older who have developed hypersensitivity to E. coli-derived<unk> . The FDA granted the application for<unk>  erwinia chrysanthemi (recombinant)-rywn fast track and orphan drug designations. Food manufacturing The most common use of<unk> s is as a processing aid in the manufacture of food.<unk> s are used as a food processing aid to reduce the formation of acrylamide, a suspected carcinogen, in starchy food products such as snacks, biscuits and fried potato. Pre-treatment of potato slices by<unk>  prior to frying reduced the acrylamide contents in the processed chips up to 81% compared to untreated control.<unk> s are marketed under the brand names Acrylaway and Preventase.
