“…The wide ecological range and fast growth of C. glomerata is a strategy which allows it to establish dominance over other macroalgae in water ecosystems [13]. This fact, confirmed in previous studies, has shown that the species belonging to the genus Cladophora (C. glomerata, C. rivularis, C. fracta) well tolerates a wide range of habitat requirements [12,14]. Additionally, mat formation, morphological variability, and chemical defense strategies used by FGA are the components of its stress avoidance mechanisms.…”

“…We have shown for the first time the evidence of morphological changes at the cellular level in the filaments of C. glomerata in response to a biotic factor which is the appearance of exudates as a result of thalli accumulation. The effect of abiotic factors on morphological changes has been partly described by Whitton [16], Pikosz and Messyasz [12]. Filamentous green algae often form monospecies mats in water ecosystems.…”

“…Filaments of C. glomerata formed monoalgal mats in the Samica Stęszewska river, Lake Oporzynskie; they co-existed with Rhizoclonium sp. Kützing in Mogilnica river and with Cladophora fracta (L.) in Malta reservoir [11,12]. The wide ecological range and fast growth of C. glomerata is a strategy which allows it to establish dominance over other macroalgae in water ecosystems [13].…”

Filamentous green algae (FGA) frequently forms dense mats which can be either mono- or polyspecies. While various defense mechanisms of competition in algae are known, little is known about the interactions between different species of FGA. An experiment in controlled laboratory conditions was conducted to gather data on the changes in amino acids (AA) concentrations in FGA species in the presence of exudates from different other species. The aim of the present study was to identify the AA whose concentrations showed significant changes and to assess if the changes could be adaptation to stress conditions. The major constituents of the AA pool in Cladophora glomerata, C. fracta and Rhizoclonium sp. were Glutamic acid (Glu), Aspartic acid (Asp) and Leucine (Leu). In response to chemical stress, that is the increasing presence of exudates, a significant increase in the concentrations Proline (Pro) and Tryptophan (Trp) was noted. The increase in Proline levels was observed in C. fracta and Rhizoclonium in response to chemical stress induced by C. glomerata exudates. As the concentration of exudates increased in the medium, there was a progressive shift in the pattern of AA group in FGA.

“…The most commonly investigated macroscopic green algae in Polish freshwater ecosystems is Cladophora glomerata (L.) Kütz. (Pikosz & Messyasz ) but other taxa including Ulva (Messyasz & Rybak ) and Oedogonium (Szymańska et al ) have also been studied.…”

SUMMARY Usually marine algae are an excellent source of pigments for different commercial sectors. Freshwater macroalgae can be exploited as a good source of biologically active compounds provided an appropriate extraction method is developed. The efficiency of four methods, like microwave‐assisted (MAE), ultrasound‐assisted extraction (UAE), supercritical fluid extraction (SFE) with ethanol as a co‐solvent, as well as conventional Soxhlet extraction were studied in the same conditions (time, solvent and temperature) for the recovery of chlorophylls and carotenoids from three freshwater green algae species: Cladophora glomerata, Cladophora rivularis and Ulva flexuosa. UV‐Vis spectrophotometry was used to determine chlorophyll a, chlorophyll b and total carotenoid content in obtained extracts. The results of this study showed that the advantages of novel extraction techniques (MAE and UAE) include higher yield and, in consequence, lower costs compared to traditional solvent extraction techniques. These methods were much more efficient in freshwater green algae pigment recovery than the classic Soxhlet extraction as well as SFE.

“…Polish reservoirs of algal biomass lie in the lakes and rivers, not in the sea -but those are still considerable [5]. Often perceived as a nuisance or an outright danger to biodiversity (when in bloom), naturally occurring algal species like Cladophora glomerata or Ulva flexuosa find little to no use in the abovementioned sectors of industry.…”

During our studies concerning the isolation of sulfated polysaccharides (SPs) from freshwater algae species widespread in Poland, an improved overall extraction methodology has been developed. This new, multi-step procedure allows for obtainment of several fractions that could find use in cosmetic and food industries, with the final one containing the valuable SPs, important both from economic and scientific perspective. Moreover, the process allows for easy use of typical chelating agents to remove harmful heavy metal ions without important losses in natural compounds of interest. Furthermore, a material balance has been established for said process, allowing for its easier implementation on bigger scales, and highlighting the areas which could still be improved to positively affect the final time-cost ratio of the methodology. Combined with previously published information concerning the detailed composition of obtained fractions, we aim to provide a robust and informative outlook on the potential of native freshwater algae species as cheap, raw and easily purifiable resource, usable in a number of important industries. According to the mass balance, nearly 5 % of dry mass of Cladophora glomerata is extractable with ethanol and this fraction consists mostly of fatty acids, phenolics and pigments. Another 5 % of mass can be isolated as pure SPs from aqueous fraction. Additionally, calcium from natural incrustations on the surface of C. glomerata amounts to 17 % of dry material weight and can be reclaimed from acidic wash by simple precipitation; such calcium salts have garnered significant interest as nutritional supplements.
