“…Almost seven different areas were studied to make a comparison on fungal community. The study also focuses on the effect of microbial growth in the soil that results in the changes of soil texture, soil profile, soil humidity, depth of sandy gravel components, ground water level, plant community as well as the other organic composition of the soil [80][81][82][83][84][85][86][87][88].…”

There is a wide range of diverse soil and aquatic microbes reside in different deltas of the world that mainly exhibit in various forms such as bacteria, fungi, parasites, archaeans, actinomycetes, virus etc. They contribute to the environment in various ways to maintain the balance of natural elements, bio geological components and also help in protecting the ecological components. Microbes that are living in the soil provide plants along with environmental and natural protection from diseases and pests. They are very much essential for transforming nitrogen and nutrients into the forms that is consumable for plants. Decomposition, production of Oxygen, evolution, as well as symbiosis are the vital roles that are played by different soil and aquatic microbes. Some river deltas show maximum populations of saline soil dependent bacterial and fungal community, where as some river deltas are enriched with some specific microbes that are responsible for soil remediation. In some cases some species of hydrocarbon degrading microorganisms contribute to differences in C, N, P ratios. As the microbes are also responsible for producing different antigens as well as allergens that are mainly causative agents for varying infectious diseases, in need of its curative drugs and antibiotic medicines some microbes are involved in research studies for production of medicinal drugs and anti-allergens.

“…The strains of Coelastrella terrestris were isolated in the foreland of Sölheimjökull glacier from a small brook “where macroscopic mucilaginous mats of reddish cyanobacteria dominated” (Iceland) [ 167 ], from soil in Czechia [ 171 ], from alpine soil near the village Obergurgl, Tyrol (Austria) [ 172 ], and from soils in Pirin Mountains (Bulgaria). It was found in the soil crusts from sand dunes of the Danube Delta, Odesa Oblast (Ukraine) [ 173 ] ( Table 2 ).…”

Microalgae are the richest source of natural carotenoids, which are valuable pigments with a high share of benefits. Often, carotenoid-producing algae inhabit specific biotopes with unfavorable or even extremal conditions. Such biotopes, including alpine snow fields and hypersaline ponds, are widely distributed in Europe. They can serve as a source of new strains for biotechnology. The number of algal species used for obtaining these compounds on an industrial scale is limited. The data on them are poor. Moreover, some of them have been reported in non-English local scientific articles and theses. This review aims to summarize existing data on microalgal species, which are known as potential carotenoid producers in biotechnology. These include Haematococcus and Dunaliella, both well-known to the scientific community, as well as less-elucidated representatives. Their distribution will be covered throughout Europe: from the Greek Mediterranean coast in the south to the snow valleys in Norway in the north, and from the ponds in Amieiro (Portugal) in the west to the saline lakes and mountains in Crimea (Ukraine) in the east. A wide spectrum of algal secondary carotenoids is reviewed: β-carotene, astaxanthin, canthaxanthin, echinenone, adonixanthin, and adonirubin. For convenience, the main concepts of biology of carotenoid-producing algae are briefly explained.

“…Much less species number was detected in biocrusts of the present study mostly concerned with identi cation of the most frequent and dominating species. While complete species composition of algae and cyanobacteria of biocrusts was showed in Schulz et al 2015 and related papers (Mikhailyuk et al 2019(Mikhailyuk et al , 2021. It was determined using different methods and so-called integrative approach: direct microscopy, enrichment and pure cultures, molecular identi cation of some species etc.).…”

Aim Biological soil crusts (biocrusts) are autonomous ecosystems consisting of prokaryotic and eukaryotic microorganisms growing on the topsoil. They colonize global climatic zones, including temperate dunes. This study examines changes in the community structure of biocrust phototrophic organisms along a dune chronosequence at the Baltic Sea compared to an inland dune in Northern Germany. Methods The community composition and their shift between different successional stages of dune development were related to physico-chemical sediment properties. A vegetation survey followed by species determination and sediment analyses were conducted. Results The findings highlighted a varying phototrophic community composition regarding the different dune successional stages. In both study sites, a shift from algae-dominated biocrusts in younger to lichen- and moss-dominated biocrusts in later successional dune types was observed. This underlined a zonation from young to mature biocrusts along a dune chronosequence. The algae community of the two study sites shared 50% of the identified species while the moss and lichen community shared less than 15%. This indicates a more generalized occurrence of the algal species along both dune chronosequences. The mosses and lichens showed a habitat-specific species community. Moreover, an increase in the organic matter and moisture content with advanced biocrust development was detected. The enrichment of phosphorus in the different biocrust types showed a similar relationship. Conclusion This relation is explainable by biomass growth and potential phosphorus mobilization from the underlying sediment by microorganisms. The observed biocrust development supported nutrient enrichment and biomass accumulation and potentially maintained in turn soil formation.
