The use of unicellular algae to remove xenobiotics (including drugs) from wastewaters is one the rapidly developing areas environmental protection. Numerous data indicate that for efficient phycoremediation three processes are important, i.e. biosorption, bioaccumulation, and biotransformation. Although biosorption bioaccumulation do not raise any serious doubts, biotransformation more problematic since its products can be potentially toxic than parent compounds posing a threat organisms...
Abstract Using a gas chromatography-mass spectrometry-time of flight technique, we determined major metabolite changes during induction the carbon-concentrating mechanism in unicellular green alga Chlamydomonas reinhardtii. In total, 128 metabolites with significant differences between high- and low-CO2-grown cells were detected, which 82 wholly or partially identified, including amino acids, lipids, carbohydrates. 24-h time course experiment, show that acids serine phenylalanine increase...
The non-steroidal anti-inflammatory drug diclofenac (DCF) is one of the commonly used and frequently detected drugs in water bodies, several studies indicate its toxic effect on plants algae. Studies performed with asynchronous Chlamydomonas reinhardtii cultures indicated that DCF inhibit growth population Here, a synchronous C. reinhardtii, which all cells are same developmental phase, used. Following changes size, photosynthetic activity gene expression, we could compare, at level single...
Non-steroidal anti-inflammatory drug diclofenac (DCF) is commonly found in freshwater bodies and can have adverse effects on non-target organisms. Among the studies DCF toxicity, several ones reported its harmful plants algae. To gain a better understanding of mechanisms toxicity towards green algae, we used synchronous Chlamydomonas reinhardtii cc-1690 culture compared (135 mg/L) with caused by atrazine (ATR; 77.6 μg/L), an herbicide well-known mechanism toxic action. achieve our goal, cell...
SUMMARY Chlamydomonas reinhardtii cia3 mutant is deficient in activity of CAH 3, a carbonic anhydrase isoform necessary for proper functioning photosystem II (PS II). We used to verify the hypothesis that despite high concentration external CO 2 , deficiency 3 results slight disorder photosynthesis, which leads mild but permanent overproduction reactive oxygen species ( ROS ). As consequence, should possess ability rebalance homeostasis overcome oxidative stress induced by environmental...
The impact of oxydiacetate oxidovanadium(IV) complexes on plants is currently unknown. This report demonstrates the influence these Arabidopsis thaliana (L.) Heynh. In presence 10−6M vanadium(IV) complexes, proceeded through their entire life cycle, with occurrence proper morphological and cytological organisation leaf root tissues. addition 10−1M H2O2 caused damage, necrosis, plant death at around seventh day, due to destruction system. Pretreatment compounds: VOSO4 VO(oda), alleviated...
Photosynthetic organisms strictly depend on CO2 availability and the CO2:O2 ratio, as both CO2/O2 compete for catalytic site of Rubisco. Green alga Chlamydomonas reinhardtii, can overcome shortage by inducing CO2-concentrating mechanism (CCM). Cells transferred to low-CO2 are subjected light-driven oxidative stress due decrease in electron sink. Response environmental perturbations is mediated some extent changes lipid carotenoid metabolism. We thus hypothesize that when cells challenged...
The fluorochrome JC-1 is mainly used in mammalian cells to estimate mitochondrial membrane potential (MMP) as a stress marker, with far less data being available for plants or green algae. To address this, we have validated the possibility changes MMP be sensitive indicator alga Chlamydomonas reinhardtii. optimize method, analyzed conditions applicable determination, including proper buffer, excitation/emission wavelengths, and solvent (dimethyl sulfoxide, DMSO) influence on fluorescence...
Abstract Drosera intermedia grows in acidic bogs parts of valleys that are flooded winter, and often dry out summer. It is also described as the sundew most heavily hydrated habitats peatlands, it found water even underwater. This only one can tolerate long periods submersion, more importantly produces a typical submerged form live such conditions for many years. Submerged occupied by D. relatively frequently. The aim study was to determine environmental architecture individuals . features...
AbstractAbstractMorphometric and stereological analysis was used to study ultrastructural changes induced in two Scenedesmus strains by oil pollution. The exhibited quite different susceptibilities aqueous fuel extract (AFOE): quadricauda (Turpin) Brébisson G-15 resistant, but microspina Chodat B2-76 sensitive a hydrocarbon concentration of c. 50 ppm. Both were grown batch culture system for 7 d on AFOE, after which they analyzed morphometrically. Circumferences the cells their components...
Obecne w wodach niesteroidowe leki przeciwzapalne (NLPZ) są zagrożeniem dla wszystkich poziomów troficznych łańcuchów pokarmowych, również zdrowia człowieka. Ze względu na ciągły dopływ NLPZ do ekosystemów, istniejące dane o zanieczyszczeniu wód gruntowych i powierzchniowych tymi związkami oraz ich potencjał bioakumulacyjny, istnieje potrzeba monitorowania środowiska pod kątem obecności skutków działania. Nieodzownym elementem badań środowiskowych jest bioindykacja, pozwalająca określić...
