EN Nowadays, the need to use of alternative feedstocks for bioenergetic purposes is urgent demand. Compared to other feedstocks, algae can provide a high-yield source of bioenergy without compromising food supplies, rainforests or arable land. Furthermore, algae present one of the technologies for the [...]

EN Metal sorption capacity of Chlorella kessleri and two strains of cyanobacteria (Aphanocapsa sp., Anabaena flos-aquae) was studied. It was found that among studied organisms, dead cells of C. kessleri were the most effective sorbents of Pb, Cu, Cd and Zn. They displayed the highest cation-exchange (C[...]

PL Glony są organizmami samożywnymi, fotosyntetyzującymi. Wykorzystują związki biogenne do produkcji swojej biomasy, z tego względu mogą być z powodzeniem wykorzystywane do oczyszczania różnego typu ścieków, bogatych w związki azotu i fosforu. Procesy usuwania zanieczyszczeń i związków biogennych przy [...]
EN Algae are fotoautotrophic organisms, which are able to use nutrients like phosphorus and nitrogen compounds to build their biomass. It is the reason why they are successfully used to treat different types of wastewaters. Processes of removing nutrition compounds and other contaminations with algae b[...]

EN The examination of the composition and dynamics of periphytic communities took place in three lakes of similar morphometry . Lake Wielkowiejskie, Budzyńskie and Dębiniec, situated in the Wielkopolska region, (Western Poland). These lakes are typical macrophyte-dominated, shallow and polymictic water[...]

EN Phosphorus deficiency is frequently the limiting factor in phytoplankton growth and the major source of selective pressure on single populations in a variety of aquatic environments. Phytoplankton species have several mechanisms that allow them to overcome phosphorus starvation, such as high-affinit[...]

PL Omówiono problem zakwitów powierzchniowych zbiorników wodnych. Obok konwencjonalnych metod zwalczania zakwitów przedstawiono nową metodę kontroli wzrostu fitoplanktonu za pomocą rozkładających się słomy jęczmiennej.
EN The problem of algal blooms in surface water reservoirs has been discussed. Besides the conventional methods for combatting the algal blooms there is presented in the paper a new method for control of the growth of algae by means of the rotting barley straw.

PL Mazuelloidy - nieformalna pod względem taksonomicznym grupa jednokomórkowych glonów - została udokumentowana w pelagicznych fosforytowych osadach syluru i dolnego dewonu Gór Bardzkich (Sudety). Organizmy te są zbudowane z kulistego ciała centralnego wielkości 100­200 :m zaopatrzonego w wyrostki dług[...]
EN Mazuelloids - a taxonomicaily informal group of unicellular algae were documented in Silurian-Lower Devonian, pelagic phosphate deposits in the Bardzkie Mts (Sudetes). These organisms consist of a spheroidal central body as much as 10-200 pm in diameter, provided in processes that range in size from[...]

PL Stan wód powierzchniowych ulega ciągłemu pogorszeniu. Jednym z jego przejawów jest eutrofizacja. Wskutek eutrofizacji dochodzi do wzrostu liczebności glonów w biomasie zbiornika wodnego. Glony powodują zanieczyszczenie wód, a wyrzucane na brzeg zbiornika wodnego traktowane są jako odpad. Odpad ten m[...]
EN Surface waters are increasingly contaminated with biogenic elements. One of the concequences is eutrophication. Eutrophication can lead to an accelerated growth of phytoplankton. The result will very often be an increase in phytoplankton biomass and a subsequent reduction in the amount of light reac[...]
