“…Previous investigations in the literature have revealed the formation of ROS in phytoplankton subject to polycyclic aromatic hydrocarbons (PAHs) such as phenanthrenequinone, anthraquinone (Tukaj and Aksmann 2007), and fluoranthene (Liping and Zheng 2008) as well as the interference of antioxidant defending system operations after anthracene exposure (Aksmann and Tukaj 2008). The interactions between these hydrocarbon compounds with ROS support our hypothesis that crude oil, which contains thousands of different hydrocarbons, causes oxidative stress and damage in phytoplankton.…”

“…Previously, some studies (Tukaj 1987;Koshikawa et al 2007;Sargian et al 2007;Aksmann and Tukaj 2008;Ozhan et al 2014a) reported changes in chlorophyll pigments as a target for crude oil toxicity in phytoplankton. While Koshikawa et al (2007) and Aksmann and Tukaj (2008) reported that there was no significant effect of crude oil in Chl a content; Tukaj (1987) and Sargian et al (2007) observed some changes in Chl a content of phytoplankton under crude oil exposure. Sargian et al (2007) used ultraviolet-B radiation with crude oil exposure so the measured impact of the two was synergistic.…”

“…Toxic effects of crude oil on phytoplankton have been studied extensively and revealed that phytoplankton, which diverge greatly in physiological properties, vary their response and tolerance to oil toxicants ; (Liu et al 2006;Hjorth et al 2007;Meng et al 2007;. Crude oil has been shown to interfere with photosynthetic processes and respiratory mechanisms and affect total primary production of phytoplankton (Miller et al 1978;Karydis 1979;Bate and Crafford 1985;Harrison et al 1986;Aksmann and Tukaj 2008;Gonzalez et al 2009). Lipophilic oil compounds accumulate in the cell membrane and change its structural and functional properties, including the loss of cell permeability, and cause other types of irreversible damage at the cell surface (Sikkema et al 1995).…”

Exposure of phytoplankton to the wateraccommodated fraction of crude oil can elicit a number of stress responses, but the mechanisms that drive these responses are unclear. South Louisiana crude oil was selected to investigate its effects on population growth, chlorophyll a (Chl a) content, antioxidative defense, and lipid peroxidation, for the marine diatom, Ditylum brightwellii, and the dinoflagellate, Heterocapsa triquetra, in laboratory-based microcosm experiments. The transcript levels of several possible stress-responsive genes in D. brightwellii were also measured.

“…The biological and chemical composition of phytoplankton would be changed at the high concentration contamination (Fiala and Delille 1999;Shi et al 2001;Hjorth 2008). The toxicity of oil WAF worked by the decrease of CO 2 and nutrients absorption (Koshikawa et al 2007;Sargian et al 2007), inhibition of photosynthesis and respiration (Singh and Kumar 1991;Aksmann and Tukaj 2008;Stepaniyan 2008), damage of cell structure and membrane system (Sikkema et al 1995), interference of antioxidation defending system operation (Aksmann and Tukaj 2008;, and blockage of nuclear acid and protein synthesis (Bopp and Lettieri 2007). However, the biomass of phytoplankton significantly increased at low concentrations of oil WAF (Figs.…”

To evaluate the effects of crude oil water accommodated fraction (WAF) on marine phytoplankton community, natural phytoplankton collected seasonally from the Yueqing bay were exposed to eight groups of crude oil WAF for 15 days under laboratory conditions. Chlorophyll a and cell density were measured, and species of phytoplankton were identified every 24 h to reflect the change of phytoplankton community. The results showed that (1) High concentrations (≥ 2.28 mg l(-1)) of oil pollution would greatly restrain phytoplankton growth (p<0.001), decrease chlorophyll a content and cell density, whereas low concentrations (≤ 1.21 mg l(-1)) did not restrain its growth but rather promoted the phytoplankton growth. (2) The biodiversity, evenness, and species number of phytoplankton were all significantly influenced by crude oil WAF in all seasons (p<0.001). (3) The dominant species changes were different under different pollutant concentrations in different seasons. Different species had different tolerances to the oil pollution, thus leading to abnormal succession.

Conditioned medium factor produced and released by Desmosdemus subspicatus and its effect on the cell cycle of the producer

Conditioned medium (CM) containing algal exudates released by cells of Desmodesmus subspicatus (green microalga) enhanced proliferation of the producer in a dilution-dependent manner, and twofold diluted CM (CM/ 2) appeared to be the most effective. Asynchronous and synchronized by light/dark regime (14/10 h) cultures of D. subspicatus were used to explain the effects of CM/2 on photosynthesis as well as growth and reproductive processes of cell cycle of the producer. During the light period, all control cells attained three commitment points (CP) triggering the reproductive processes and 20% of them, additionally the fourth one. This resulted in the formation of mainly eight and partly 16 autospores released from the parent cell during the dark period of the cell cycle. CM/2 markedly increased the number of cells that attained the fourth CP. Chlorophyll a fluorescence parameters, measured by OJIP test (O, J, I, and P-different steps of fluorescence induction curve), were applied to explain stimulatory effect of CM/2 on the rate of oxygen evolution. The number of cells as well as the parameter of their "vitality" (P.I) determined by OJIP analysis were equally enhanced by CM/2. The maximum yield of electron trapping and transport, as well as the fraction of active reaction centers, was also significantly higher in CM/2. The cells quickly produced and released CM factor (CMF) to the culture medium; its highest activity was observed in the middle light phase of the cell cycle. Dialysis, ion exchange chromatography, and solid-phase extraction with C 18 allowed reproducible extraction of the active compound from CM. Subjecting the extract to reverse-phase highperformance liquid chromatography led to one active fraction eluted as a peak with the shortest retention time indicating its hydrophilicity.
