The effect of fuel oil on the ultrastructure of the chlorococcal algaScenedesmus armatus

Biodiesel Production from Scenedesmus sp. through Optimized in situ Acidic Transesterification Process

“…2 also clearly demonstrated the effect of high pressure homogenization pretreamtment process by showing that complete destruction of the cell walls after the pretreatment, which can definitely enhance the biodiesel produciton yield from in situ transesterficiation as also reported elsewhere. 28,29,31 As shown in Fig. 2 (B), the starch droplets (white vacuole), and the widespread crushed cytosol and stroma of chloroplasts (grey amorphous materials) were observed while for non-treated biomass the cell wall maintained their own circular shape.…”

“…Effect of high pressure homogenization on in situ transesterfication process Most of of marine micaroalgae, are known to have the ultrastructure of cell wall referred to as ribs and a trilaminar structure and especially, Scenedesmus sp., the subfamily Scotiellocystoideae, has very solid three-layered (cellulosic layer→middle layer→cell organelles) cell walls, 28,29 which is commonly described feature for these subfamily. 30 Thus, various pretreatment processes such as homogenization, ultrasonication and microwave, etc.…”

Photoacoustic study of the effect of fuel oil on the photosynthetic system of algae Scenedesmus armatus

“…The ratio of PA signal for samples with fuel oil to a reference one for control samples reaches its maximum after 7 days of culture growth. It is known that at such period corresponds to maximal changes in chloroplasts structure under the action of AFOE [8]. The fine structure of Scenedesmus amzatus cells cultured for 7 days without and with AFOE (90%) is displayed at Fig.…”
