| Description | Species of genus Trebouxia are green microalgae, well known as photobionts, i.e. photosynthetizing partner in lichen association. Trebouxia sp. is present in two thirds of all lichen species. It is frequently found also in extremophilic lichens from Antarctic habitats. It is an unicellular green alga, size of which is about 10 – 15 micrometres in diameter. In spite of the fact that several species of genus Trebouxia are cultivated as stock items in many culture collections, surprisingly little is known about their basic physiological characteristics. Over last few decades, photosynthetic parameters of Trebouxia sp. have been scarcely investigated. However, basic knowledge on their photosynthetic responses to osmotic (Váczi et Barták 2006), high light (Showman 1972), oxidative (del Hoyo et al. 2011) and heavy metal-induced stress (Alvarez et al. 2012) is available. The aim of presented study was to evaluate optimal growth temperature of isolated Trebouxia sp. when cultivated in liquid medium and changes in photosynthetic performance as dependent on cultivation temperature. |
