“…Microcoleus chtonoplastes ) from hot deserts soils was described as a new genus, Desertifilum [ 297 ]. The transect study covering 800 km and three soil types (lateritic soils, red soils and soils burdened by mine-waste) in arid region in eastern India revealed the general common composition of the biological crusts, which comprised Scytonema , Tolypothrix and Lyngbya along with few species from Cylindrospermum , Nostoc , Calothrix and Fischerella [ 303 ]. Although most of the abovementioned species were toxigenic in other habitats ( Table 1 ), algae from hot deserts and other arid habitats have been rarely studied in relation to phycotoxins.…”

The review summarizes the available knowledge on toxins and their producers from rather disparate algal assemblages of aeroterrestrial, airborne and other versatile extreme environments (hot springs, deserts, ice, snow, caves, etc.) and on phycotoxins as contaminants of emergent concern in soil and plants. There is a growing body of evidence that algal toxins and their producers occur in all general types of extreme habitats, and cyanobacteria/cyanoprokaryotes dominate in most of them. Altogether, 55 toxigenic algal genera (47 cyanoprokaryotes) were enlisted, and our analysis showed that besides the “standard” toxins, routinely known from different waterbodies (microcystins, nodularins, anatoxins, saxitoxins, cylindrospermopsins, BMAA, etc.), they can produce some specific toxic compounds. Whether the toxic biomolecules are related with the harsh conditions on which algae have to thrive and what is their functional role may be answered by future studies. Therefore, we outline the gaps in knowledge and provide ideas for further research, considering, from one side, the health risk from phycotoxins on the background of the global warming and eutrophication and, from the other side, the current surge of interest which phycotoxins provoke due to their potential as novel compounds in medicine, pharmacy, cosmetics, bioremediation, agriculture and all aspects of biotechnological implications in human life.

“…Moreover, for the better evaluation of the lichens, the determination of the algae type and the details of the ascocarp-shaped structure have been done by sharp blade cutting and optical microscope observation (Echo um-210 BD). After cultivating, we identified species based on related researches including (Fang et al, 2007;Bilgrami and Saha, 2004;Komárek, 2005;Luton et al, 1999;Johnson et al, 2005;Hassler et al, 2012;Vijayan and Ray, 2015;Kumar et al, 2016;Moniri and Sipman, 2009;Zedda et al, 2000;McCune, 2007).…”

The effects of biocrusts on soil parameters in a semi-arid pediment at north-eastern Iran

The biocrusts are organized by soil-surface communities of biota that live within or on the very top of soil surface and play an important role in soil conservation. They include lichens, mosses, fungi, cyanobacteria, eukaryotic algae, and other heterotrophic bacteria. The interaction between biocrusts and soil is very important and good awareness from that help to better manage soil specially in arid and semi-arid areas. The linkage between cyanobacteria species and soil physicochemical parameters and mineralogy in two geomorphic zones in the northeastern Iran was studied. Samples were collected in summer along a linear transect by using 50 x 50 cm quadrates for each study zone. Individual mineral soil particles were analyzed by a scanning electron microscopy (SEM). The amounts of Na, K, Ca, and Mg contents as well as EC and SOC altered significantly between two study zones. Biocrusts increased levels of organic carbon, pH, calcium carbonate, exchangeable sodium and potassium percentages. The main soil properties of SOC, CaCO3 and amount of clay changed among biocrust sand bare soils.
