“…(da Silva et al 2015) were described for For the Paraná hydrographic region while a species of Conjugatophyceae, Staurastrum Meyen ex Ralfs (Santos et al 2013) and a Cyanophyceae belonging to the genus Pannus Hickel (Malone et al 2014) were described for the Paraguay hydrographic region (pantanal of Nhecolândia, Mato Grosso do Sul state). For the Amazon hydrographic region the monotypic new genera Eunotioforma Kociolek & Burliga and Bicudoa C.E.Wetzel et al (Wetzel et al 2012a;Burliga et al 2013), as well as a species of Tursiocola R.W.Holmes et al (Wetzel et al 2012b) and another of Aulacoseira Thwaites (Tremarin et al 2013b) were described.…”

“…New occurrences and, more noticeably, the description of new taxa of microalgae were also a result of the increase in collection efforts, particularly the work regarding diatoms and cyanobacteria carried out by Wetzel et al (2012a, b), Gama Jr. et al (2012, Burliga et al (2013), Caires et al (2013), Santos et al (2013) and Tremarin et al (2013).…”

An updated synthesis of cyanobacteria and algae information is presented for Brazil aiming to refine the data gathered to date and evaluate the progress of the biodiversity knowledge about these organisms in the country since the publication of the Catálogo de Plantas e Fungos do Brasil. The results of 2015 showed an increase of 1,250 species (35.7%) when compared to 2010, reaching a total of 4,747 species. The most diverse classes in species number were the Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae and Euglenophyceae. Bacillariophyceae and Cyanophyceae had the highest increase in species number in the five-year interval. The Southeast and South regions were the most diverse, however, the Northeast, with the states of Piauí and Sergipe, and the Central-west region, with Mato Grosso, Goiás and Distrito Federal, also stood out in the national algal biodiversity scenario. Despite the shortage of taxonomists and limited infrastructure, the results showed a significant improvement in the knowledge regarding the diversity of cyanobacteria and algae in the country during the study period, starting to even out regional geographical differences caused by subsampling. Key words: Biodiversity, phycology. ResumoApresenta-se uma síntese atualizada de informações sobre algas no Brasil objetivando refinar os dados reunidos até o presente, bem como avaliar os avanços sobre o conhecimento da diversidade de algas no país desde a publicação do Catálogo de Plantas e Fungos do Brasil. Os resultados de 2015 mostraram um acréscimo de 1.250 espécies (35.7%) a um total de 4.747 em relação a 2010. As classes mais diversas em número de espécies foram Bacillariophyceae, Conjugatophyceae, Florideophyceae, Cyanophyceae, Dinophyceae e Euglenophyceae. Bacillariophyceae e Cyanophyceae tiveram o maior acréscimo de espécies no intervalo de cinco anos. A região Sudeste e Sul foram as mais diversas, porém, as regiões Nordeste com os estados do Piauí e Sergipe e Centro-Oeste com os estados de Mato Grosso, Goiás e Distrito Federal destacaram--se no cenário da biodiversidade nacional. Apesar da escassez de taxonomistas e da infraestrutura limitada, os resultados obtidos evidenciaram um avanço significativo no conhecimento da diversidade de algas no país nesse período de cinco anos, iniciando uma mudança quanto as diferenças geográficas regionais. Palavras-chave: Biodiversidade, ficologia.

The research includes a study of evaluating the treatment efficiency of the sewage plant in the Tuz Khurmatu district during the period from September 2020 to July 2021. Three study sites have been selected. The study includes measuring certain physicochemical and biological properties of water (the biological properties include studying the quality of algae). As for the physicochemical properties, they include measuring (air and water temperature, pH, dissolved oxygen, biological oxygen requirement (BOD5), active phosphate and active silicates).The results found that air temperature ranges between 12-49°C, while the water temperature ranges between 9-40°C. The pH values have a wide range during the months of the study ranging between 6.20 -8.45. The values of the dissolved oxygen range between 1.25-3.10 mg/L, and the values of the biological requirement for oxygen range between 19.2-47.2mg/L. The study also shows that the wastewater during the study period is of a light basicity in which bicarbonate ions prevail. Nutrient concentrations fluctuate depending on the nature of the site and the date of sample collection, as the effective phosphate ranges between 2.32-7.76 mg phosphorous-phosphate/liter. As for the silicate values, they range between 0.38-6.61 mg atom of silicon -silica / liter.
