Biological crusts of serpentine and non-serpentine soils from the Barberton Greenstone Belt of South Africa
(Springer, 2017)Climate and geography can influence biological soil crust (BSC) community composition, but local heterogeneity in variables such as soil characteristics or microclimate gradients can also impact cryptogamic diversity. Heavy ... -
Changes in density and composition of algal assemblages in certain unit processes of two South African water purification plants
(Taylor & Francis, 2014)The water purification plants at Virginia and Bothaville, South Africa, experience problems with cyanobacteria and other algae. Their algal assemblages were studied during 2010 and 2011 to determine the dominant species ... -
Changes in the algal composition and water quality of the Sundays River, Karoo, South Africa, from source to estuary
(Taylor & Francis, 2015)A first survey was done on algae present in the Sundays River from its source to its confluence with the sea. Species found in the upstream sections of the river included indicators of good water quality, but the quality ... -
First record of a cyanobacterium Petalonema alatum (Borzì ex Bornet & Flahault) Correns (Cyanobacteria, Scytonemataceae) in Africa
(Pensoft, 2018)Petalonema alatum (Borzì ex Bornet & Flahault) Correns is a nitrogen fixing, subaerial cyanobacterium characterized by a blue-green trichome surrounded by a very broad, lamellated mucous sheath. It typically grows on ... -
First record of a spiral form of Aulacoseira, A. ambigua f. japonica (F.Meister) Tuji & D.M.Williams, in South African fresh waters
(Taylor & Francis, 2016)Water quality and algal populations in the Vaal River Barrage Reservoir have been monitored extensively for many decades, because of its importance as a water source for the most densely populated area in South Africa. ... -
Gomphonema grande sp. nov., a new diatom (Bacillariophyta) from the Democratic Republic of the Congo, Tropical Africa
(Magnolia Press, 2016)Gomphonema grande sp. nov. is described from a single sample collected from the Congo River Basin, Tropical Africa. The morphological features of the new species are described and documented through light microscopy and ... -
The identification of organic substances associated with freshwater Ceratium hirundinella cells
(Schweizerbart Science, 2018)Phytoplankton synthesize biomolecules through the process of photosynthesis, and the decomposition of these molecules causes odors in water. While the freshwater dinoflagellate Ceratium hirundinella is well known for causing ... -
Laboratory-scale simulations with hydrated lime and organic polymer to evaluate the effect of pre-chlorination on motile Ceratium hirundinella cells during conventional water treatment
(Water Research Commission, 2016)Algal genera such as Carteria, Chlamydomonas, Chlorogonium, Cryptomonas, Ceratium, Peridinium and Euglena are motile and may disrupt unit processes and cause water treatment problems. Algal species belonging to these ... -
More good news about polymeric plant- and algae-derived biomaterials in drug delivery systems
(Bentham Science, 2014)Natural polymers are continuously investigated for use in pharmaceutical and tissue engineering applications due to the renewability of their supply. Besides the conventional use of natural materials in dosage form design ... -
Phycoremediation: a solar driven wastewater purification system
(Wiley, 2019)Abstract: This chapter contains sections titled: Introduction -- Organisms Employed in Phycoremediation -- Phycoremediation -- Fate of the Chemicals -- General Enzymes Involved in Bioremediation -- Genetic ...
