摘要：
The work is dealing with usage of various waste materials as potential carbon source for production of microbial biopolymers. Mainly lignocellulosic waste has been tested for biotechnological production of biopolymers, namely polyhydroxyalkanoates and extracellular polysaccharides. Chemical and enzymatic hydrolysis or combination of both were applied to following lignocellulosic materials; spent coffee ground, waste wood, apple pomace and wheat bran. As the result of hydrolysis process, relatively high concentration of fermentable sugars is formed, but also wide range of inhibitors can be generated (e.g. furfural, levulinic acid, polyphenols). Several extraction steps were used for detoxification of hydrolysates. Waste frying oil, cheese whey or waste glycerol has been also used for production of biopolymers which are mentioned above.
