“…This period is characterized by an almost 2-fold increase in CA in С. crinita compared with that in April and by a 2.2 increase in F. vesiculosus. A sharp increase in metabolic activity during this period is also shown for the latter species [6].…”

“…CA values in F. vesiculosus varied slightly from May to October. The stably high catalase activity in F. vesiculosus during that period is indicative of the intensive efficacy of the components of the antioxidant system, which is also confirmed by the increased metabolic activity of F. vesiculosus cells, especially in July-August [6]. These facts are in line with the data [16] that show the high resistance of F. vesiculosus to high temperatures, PAR (photosynthetically active radiation) intensity and UV (ultraviolet radiation) compared with other dominant boreal macroalgae species (Saccharina latissima = Laminaria saccharina (Linnaeus) J.V.…”

“…It is known that one of the primary abiotic factors provoking a high variation of AOS indices is temperature [5]. The data on the effects of temperature on catalase activity (CA) in the Black Sea C. crinita are fragmentary and unsystematized [3], and such studies are isolated for F.vesiculosus of the Barents Sea [6].…”

The seasonal dynamics of catalase activity of two related species of brown macroalgae, Cystoseira crinita (Desf.) Bory (1832) and Fucus vesiculosus L. (1753) was studied. In general, catalase activity (CA) in C. crinita was several times higher than in F. vesiculosus. The maximum values of CA in C. crinita were observed in November and the minimum ones in September. For F. vesiculosus, the maximum CA was found in January and the minimum in April. Abrupt changes in water temperature significantly affected the catalase activity in C. crinita and F. vesiculosus. In both species of algae, a similar seasonal trend in the change of CA was noted: two periods of adaptation adjustment associated with sharp changes in the temperature regime (spring and autumn) were distinguished. In spring, with a rapid increase in the temperature of the water masses, catalase inactivation occurred, whereas during summer to winter transition, accompanied by a sharp water cooling, catalase activity increases. Stabilization of the CA values of the studied macroalgae in the absence of sharp temperature variability was observed. However, this period of “stationary state” varies in time: in Cystoseira crinita it lasts from May to August, and in Fucus vesiculosus it lasts from May to December.

“…The formation of AFO (active forms of oxygen) in photosynthetic organisms is a mandatory process that accompanies various metabolic processes-photosynthesis, respiration, In summer period the intensity of enzyme synthesis is quite high since maximum physiological activity, growth and synthesis of spare nutrients are characterized for algae at this time of year, especially for F. vesiculosus [7]. In addition to the internal characteristics of the body, the activity of enzymes will be influenced by abiotic and anthropogenic factors.…”

Macrophyte algae are perspective indicator species for assessing the environmental impact of pollutants. One of the ways to estimate the negative impact is to change the activity of enzymes of the antioxidant system. The possibility of using hydrogen peroxide, catalase and superoxide dismutase (SOD) is analyzed in the research for assessing the anthropogenic load on algae macrophytes of different systematic groups: Palmaria palmata (L.) O. Kuntze; Fucus vesiculosus L., Ulvaria obscura (Kützing) Gayral ex Bliding. The natural level of enzymes (in July) and its change under the influence of oil products (diesel fuel) on algae growing in the Barents sea were measured. It is shown that under natural conditions the content of hydrogen peroxide and catalase activity decrease in the series U. obscura < P. palmata < F. vesiculosus; the activity of SOD decreases in the series P. palmata < U. obscura < F. vesiculosus. When diesel fuel is introduced into the habitat of algae, the concentration of hydrogen peroxide in the cells of U. obscura and P. palmata decreases and in F. vesiculosus-increases. Catalase activity in P. palmata and U. obscura increases and catalase activity is not various in F. vesiculosus. The activity of SOD in the prototypes of G. obscura and P. palmata decreases and it remains unchanged in F. vesiculosus. It is shown that the enzyme complex Ulvaria obscura can be used to assess the impact of diesel fuel and only SOD can be used in P. palmata. No reaction of SOD and CAT to the presence of petroleum products was detected in F. vesiculosus.

“…Diurnal rhythms of photosynthesis and respiration intensity, water potential, nitrogen compounds content, enzymatic activity, gene expression, etc. were revealed in plants and algae [1,2,3,4,5,6]. Higher plants have shown the presence of circadian rhythms of the content of free amino acids (FAAs): their concentration increases during the daytime [1,2].…”

Influence of environmental factors on the contents of free amino acids in Fucus vesiculosus in the Barents Sea during the day

Influence of main environmental factors (temperature, intensity of photosynthetically active radiation and tidal cycle) on the contents of free amino acids (FAAs) in Fucus vesiculosus in the Barents Sea during the day was investigated. An undular change in the content of FAAs occurs during the day, associated with the phases of the tidal cycle. Temperature and photosynthetically active radiation influenced the content of FAAs, but their relation probably is a nonlinear. The content of most of FAAs and their total amount reached the highest values at a minimum water level. The lowest values were determined when algae were in seawater. The difference in the content of individual FAAs and their common amounts averaged 1.5-3 times during the day. The reason for the changes in the content of FAAs is probably related to the metabolic processes and their switching during the transition of algae from an aquatic environment to an air and vice versa.
