Norwida 4, 20-061 Lublin, Poland e-mail: [email protected] (Received: April 7, 2003. Accepted: July 18, 2003) ABSTRACT During studies of phytoplankton in Sumin Lake (£êczna-W³odawa Lakeland), conducted from May till Sep- tember 2001 and 2002, 15 taxa of the genus Pediastrum (Hydrodictyaceae, Sphaeropleales) were found. Among them there were common species as Pediastrum boryanum, P. duplex, P. tetras and P. simplex, but also rare spe- cies as P. integrum or P. kawraiskyi. An especially interesting species was P. orientale, the taxon that until now has not been noted in phytoplankton of Polish water bodies. The paper gives descriptions of the genus Pediastrum coenobia and physico-chemical conditions of the habitat. The original documentation of Pediastrum taxa is added.

Quantification of DNA Content in Freshwater Microalgae Using Flow Cytometry: a Modified Protocol for Selected Green Microalgae
Fottea 11(2): 317–328, 2011 317 Quantification of DNA content in freshwater microalgae using flow cytometry: a modified protocol for selected green microalgae Petra MAZALOVÁ , Petra ŠARHANOVÁ , Vl a d a n On d ř e j & Aloisie PO u l í č k ov á Department of Botany, Faculty of Science, Palacký University Olomouc, Šlechtitelů 11, CZ–783 71 Olomouc, Czech Republic; e–mail: [email protected] Abstract: The study of genome size variation in microalgae lags behind that of comparable research in higher plants and seaweeds. This situation is essentially caused by: (1) difficulties in obtaining sufficient biomass for experiments; (2) problems with protoplast isolation due to cell–wall heterogeneity and complexity; and (3) the absence of suitable standards for routine measurements. We propose a multi–step protocol that leads to the quantification of DNA content in desmids using flow cytometry. We present detailed culture conditions, the minimal biomass necessary for three repetitive measurements, a method to isolate protoplasts and selection of suitable standards. Our protocol, which is mainly based on studies with higher plants and commercially available enzyme mixtures, is useful in Streptophyta, especially members of the Zygnematophyceae, because of their close phylogenetic relationship to higher plants, in particular the similarity of their cell wall organization. Moreover, the suggested protocol also works for some Chlorophyta (Chloroidium ellipsoideum, Tetraselmis subcordiformis) and Heterokontophyta (Tribonema vulgare). We suggest and characterize a new standard for flow cytometry of microalgae (Micrasterias pinnatifida). Modification of the enzyme mixture is probably necessary for microalgae whose cell walls are surrounded by a mucilaginous envelope (Planktosphaeria), those that contain alganan (Chlorella), monads with a pellicle or chlamys (Euglena, Chlamydomonas). -

Among the families Desmidaceae with 22 genera and species showed the highest species richness. Scenedesmaceae (15 species) and Oocystaceae (14 species), Hydrodictyaceae (7 species), Ulotrichaceae (3 species), Zygnemataceae (2 species), Volvocaceae (2 species) and Cladophoraceae, Oedogoniaceae and Trentephliaceae each with 1 species respectively presented in the studied sites. High population densities of species were observed in the warm months.

Isolation and Evaluation of Microalgae Strains from the Northern Territory
Isolation and evaluation of microalgae strains from The Northern Territory and Queensland - Australia that have adapted to accumulate triacylglycerides and protein as storage Van Thang Duong Master of Environmental Sciences A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2016 School of Agriculture and Food Sciences Abstract Biodiesel and high-value products from microalgae are researched in many countries. Compared to first generation biofuel crops, advantages of microalgae do not only lead to economic benefits but also to better environmental outcomes. For instance, growth rate and productivity of microalgae are higher than other feedstocks from plant crops. In addition, microalgae grow in a wide range of environmental conditions such as fresh, brackish, saline and even waste water and do not need to compete for arable land or biodiverse landscapes. Microalgae absorb CO2 and sunlight from the atmosphere and convert these into chemical energy and biomass. Thus, the removal of CO2 from the atmosphere plays a very important role in global warming mitigation, as the produced biofuel would replace an equivalent amount of fossil fuel. Based on their high protein contents and rapid growth rates, microalgae are also highly sought after for their potential as a high-protein containing feedstock for animal feed and human consumption. However, despite the promising characteristics of microalgae as a feedstock for feed and fuel, their stable cultivation is still difficult and expensive, as mono-species microalgae can often get contaminated with other algae and grazers. To address this issue I hypothesized that indigenous strains have a highly adaptive capacity to local environments and climatic conditions and therefore may provide good growth rates in the same geographic and climatic locations where they have been collected from. -
