Abstract

Sirovine i izvori kemijskih elemenata koji se koriste za hranjive podloge u industrijskoj proizvodnji dijelimo u četiri skupine: izvori ugljika, izvori dušika, minerali i sirovine korištene za posebne namjene. Kao izvori ugljika koriste se ugljikohidrati i biljna ulja. Izvori dušika su poljoprivredni te mesnih i riblji nusproizvodi ili anorganski spojevi koji sadrže dušik. Mineralne soli služe kao izvori nutrijenata, prekursori, puferi ili za kontrolu pH vrijednosti. U sirovine za posebne namjene ubrajamo sredstva protiv pjenjenja, emulgatore i kelatne agense. Sirovine biramo prema vrsti procesa i karakteristikama radnog mikroorganizma. Sve se češće kao sirovina koristi poljoprivredno-industrijski otpad zbog jeftinije cijene, a takav pristup rješava i problem odlaganja otpada. Poljoprivredno-industrijski otpad uključuje i lignocelulozne sirovine za koje je potreban dodatan predtretman kako bi se mogle koristiti u hranjivim podlogama za različite biotehnološke procese.

Abstract (english)

Raw materials and sources of chemical elements used for nutrient media in industrial production are divided into four groups: carbon sources, nitrogen sources, minerals and raw materials used for special purposes. Carbohydrates and vegetable oils serve as carbon sources. Sources of nitrogen are derived from agricultural, meat and fish nusproducts or inorganic nitrogen-containing salts. Minerals are used as sources of nutrients, precursors, buffers or pH control. Raw materials for special purposes include anti-foaming agents, emulsifiers and chelating agents. Raw materials are selected according to the type of process, and characteristics of the working microorganism. Agro-industrial waste is increasingly used as a raw material because of the cheaper price and this approach also solves the problem of its accumulation. This type of waste also includes lignocellulosic raw materials that require additional pretreatment to be used in nutrient media in various biotechnological processess.
