Tierische Proteinhydrolysate als N-Quelle für die Milchsäurefermentation
Tóm tắt
Polylactic acid, a biodegradable polymer, is an ecological alternative for petroleum-derived plastics. The biotechnological production of its precursor lactic acid demands complex carbon and nitrogen sources significantly defining the fermentation costs. Whereas a variety of waste streams have already been utilized as carbon providing substrates, there is still no cheap alternative for common peptones. Protein hydrolyzates from animal by-products could be a promising solution to fill this gap.
