Article
Full-text available
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...
Chapter
Cosmopolitan taxa of freshwater macroalgae occurring in inland waters in mass are described with respect to their biology. One of their components is autecology, which concerns the relations of individual organisms to the various factors of their environment. The factors influencing the fluctuations of macroalgal populations (e.g., Cladophora, Oedo...
Article
GAMs (Generalized Additive Models) present a growth pattern for the common filamentous algae (FA) taxa in freshwater ecosystems in Poland. Tribonema, Ulothrix taxa are an early spring species. In comparison with Rhzioclonium, Cladophora and Oedogonium taxa, the algae Zygnemataceae (e.g. Zygnema, Spirogyra) occurs in waters with lower levels of nutr...
Article
Potential factors affecting the occurrence of filamentous algae include the morphometry of water bodies, the type of substrate and physicochemical conditions of the habitat. This study attempts to describe the individual filamentous algae species recorded in Poland, taking into account the trophic and ecological characteristics based on our own res...
Article
Full-text available
The occurrence of algal-cyanobacterial metaphyton mats in field (Konojad village) and artificial ponds (Poznań city) was investigated in the Wielkopolska region. The surface area of algal mats ranged between ca. 45% (natural pond) and 10% (artificial pond) of the total water surface, and the mats occurred from the water surface to the bottom; the a...
Article
Full-text available
The effects of the impact of four organic compounds (ascorbic acid, biotin, glucose and sucrose) on ash, protein, fiber, fat and amino acid contents in the freshwater Aegagropila linnaei biomass were examined in 7 and 14 days of cultivations in high concentrations of tested compounds (100 mg L-1). The presence of examined organic compounds had a ne...

A brief review, with 19 refs., of methods for processing algae biomass for cosmetic industry including biomass harvesting , extn. with supercrit. CO 2 and formal requirements. Przedstawiono warunki optymalizacji procesu wytwarzania ekstraktu z biomasy glonów na potrzeby przemysłu kosmetycznego. Proces optymalizacji omówiono w trzech obszarach: pozy...
Chapter
On the basis of the findings from our long-term studies and all available literature from Poland, the biological and ecological characteristics of the widely distributed macroalgae taxa are presented in this chapter. Macroscopic algae from different phyla representing the two main morphological types – filamentous forms (branched or unbranched) and...
Chapter
Full-text available
This chapter presents a general analysis of biomass green algae and extracts derived from this material. At present biomass is considered a rich source of energy, liquid and gaseous biofuels, as well as valuable raw material of natural origin. Analytical chemistry has always played an important role in the application of algae biomass. The analytic...
Chapter
Full-text available
Many species of algae are valuable cosmetics raw materials because of the diversity of biologically active phytochemicals in them. The commercialization of algae starting from their harvesting and biological identification up to clinical trials of the end product is a very long and complex process. Algal products, such as micronized algae and extra...
Article
Full-text available
This study was undertaken to determine mineral content, amino acid and fatty acid composition of the freshwater macroalga – Cladophora glomerata. The studies were based on the content comparison in algal biomass collected from a lake and cultured in a laboratory. To determine the ability of copper cumulating by macroalgae, Cladophora was cultured i...
Article
Full-text available
Algological investigations were focused on taxonomy, chorology and ecology of threatened filamentous green alga species in Poland. Studies on Oedogonium capillare Kützing ex Hirn growing in large quantities in association with Clado-phora rivularis (Linnaeus) Hoek in pond were conducted. The aim of these studies was to describe the distribution, ec...
Article
Full-text available
Getting to know the response of different groups of aquatic organisms tested in altered thermal environments to environmental conditions makes it possible to understand processes of adaptation and limitation factors such as temperature and light. Field sites were located in three thermally abnormal lakes (cooling system of power plants), in eastern...

Jako organizm modelowy celowo wybrano makroskopowe zielenice z rodzaju Ulva wy-stępujące w ekosystemach słodkowodnych. Powodem skupienia badań na słodkowod-nych populacjach Ulva było rzadkie ich wy-stępowanie w wodach śródlądowych i fakt, że, w przeciwieństwie do populacji mor-skich, Ulva wykazuje zdolność do wytrącania soli wapnia na powierzchni ś...

Full-text available
Wykorzystując doniesienia literaturowe oraz wyniki badań własnych, przedstawiono występowanie, budowę chemiczną i morfologiczną alg słodkowodnych występujących także na terenie Polski oraz zastosowanie ich biomasy jako cennego surowca dla różnych gałęzi przemysłu i rolnictwa. Z powodu braku w Polsce systemu wykorzystywania biomasy alg do celów prze...

Ulva flexuosa subsp. pilifera (Kütz.) M. J. Wynne 2005 (= Enteromorpha pilifera Kützing 1845) was previously found in Argentina, the Czech Republic, Germany, Hungary, Romania, Slovakia and Sweden, recently also in Poland. The genus Ulva was first time described as Enteromorpha. Interestingly, Enteromorpha is used nowadays as a synonym for Ulva, a d...

Ulva flexuosa subsp. pilifera previously known from northern Poland, from the channel near Szczecin and ponds near Łódź, has recently been found in the Malta Reservoir in the Wielkopolska (West Poland) region. Specimens collected in the Wielkopolska region were examined in detail, also under a transmission electron microscope (TEM). The morphometri...

On the surface of the freshwater form of Ulva thalli the incrustations process takes place which resulted in the precipitate of calcium carbonate crystals (CaCO 3). At the same time, this area is also inhabited by large numbers of periphytic communities, mainly by diatoms. Siliceous frustules and calcite crystals are responsible for the thalli roug...
