Original Abstract

Microalgae are known mainly as a large group of photoautotrophic organisms producing a number of important metabolites such as carotenoids, chlorophylls, lipids, and many others. Their mixotrophic potential was investigated by adding an alternative organic carbon source to the medium. The chosen carbon sources were two types of waste oils from the food industry. The coffee oil was obtained from spent coffee grounds. The waste frying oil is a low quality product of fast food industry produced in large quantities. The aim of this work was to test the stress effect of waste frying oil and coffee oil on the growth of algae and the production of metabolites, as well as the possible utilization of the waste oils. The results of this experiment served as a precursor for further experiments on microalgae with waste substrates. The growth and production characteristics of microalgae Desmodesmus armatus, Chlamydomonas reindhartii, Scenedesmus acutus and the cyanobacteria Anabaena torulosa were tested. The results showed enhanced production of chlorophylls by the strain Desmodesmus armatus and increased lipid accumulation in the strain Chlamydomonas reindhartii.
