“…However, the free Cu(II) in the adsorption mixture was stable during incubation in the treatment of without external DOM, suggesting that the part of Cu(II) adsorbed by Aliinostoc still bound with cellular debris after cell death. Although cyanobacteria are autotrophs, they are evidenced capable of degrading organic matters, such as pesticides, dyes, and oil (Subramanian et al, 1994;El-Sheekh et al, 2009;Akoijam et al, 2015). Although cells of Aliinostoc were gradually died during long term of incubation, the uptake of Cu(II) by Aliinostoc was gradually increased during incubation in the treatment of Aliinostoc + DOM, while this phenomenon was not observed in the treatment of without DOM addition.…”

Dissolved organic matter (DOM) and Cu(II), originated from livestock manure, often co-exist in livestock effluents. The effects of DOM on adsorption of Cu(II) by adsorbent remain unknown, which may prevent the removal of Cu(II) from livestock effluents using the method of adsorption. In this study, the effects of DOM on adsorption behaviors of Cu(II) by Aliinostoc sp. YYLX235, a epiphytic cyanobacterium, were investigated. The results showed that Aliinostoc could effectively bind with Cu(II) and remove it from water. Rather than absorption, most of Cu(II) were bound on the cell surface through adsorption. The decay of Aliinostoc did not resulted in rapid release of Cu(II) into water. The amount of Cu(II) adsorbed by Aliinostoc through ion exchange and complexation was decreased by DOM addition.

“…The decrease in Chl α may have been influenced by the high amount of carbon as an energy source, causing the cyanobacteria to switch to a heterotrophic or mixotrophic type of nutrition, which resulted in a decrease in Chl α. Previous studies have shown that cyanobacteria can degrade petroleum products in contaminated waters [16,17]. Additionally, microalgae and cyanobacteria have been found to rapidly adapt to oil pollution and reproduce at low oil concentrations due to their adaptation to extreme environmental conditions [18].…”

Wastewater from oil refineries, as well as other chemical industries, has specific features. Phototrophic microorganisms are commonly used to treat wastewater containing toxic components, such as oil and petroleum products. Cultivating microalgae and cyanobacteria in nutrient-rich wastewater can yield high biomass for simultaneous biotreatment, making it a more cost-effective and environmentally friendly approach. This study investigated the species composition of microalgae in wastewater from oil refineries in the Atyrau region. The results showed that Cyanophyta representatives dominated the microalgae composition in the enrichment culture. The presence of cyanobacteria in the wastewater was attributed to the high nutrient and calcium content of the organic matter. An axenic culture of the cyanobacterium Anabaena sp. was isolated to study its ability to grow and degrade different concentrations of motor oil. The results indicate the potential of Anabaena sp. strain in remediating aquatic environments contaminated with petroleum products.

Cyanobacteria are blue-green Gram-negative and photosynthetic bacteria which are seen as one of the most morphologically numerous groups of prokaryotes. Because of their ability to fix gaseous nitrogen and carbon dioxide to organic materials, they are known to play important roles in the universal nutrient cycle. Cyanobacteria has emerged as one of the promising resources to combat the issues of global warming, disease outbreaks, nutrition insecurity, energy crises as well as persistent daily human population increases. Cyanobacteria possess significant levels of macro and micronutrient substances which facilitate the versatile popularity to be utilized as human food and protein supplements in many countries such as Asia. Cyanobacteria has been employed as a complementary dietary constituent of feed for poultry and as vitamin and protein supplement in aquatic lives. They are effectively used to deal with numerous tasks in various fields of biotechnology, such as agricultural (including aquaculture), industrial (food and dairy products), environmental (pollution control), biofuel (bioenergy) and pharmaceutical biotechnology (such as antimicrobial, anti-inflammatory, immunosuppressant, anticoagulant and antitumor); recently, the growing interest of applying them as biocatalysts has been observed as well. Cyanobacteria are known to generate a numerous variety of bioactive compounds. However, the versatile potential applications of cyanobacteria in biotechnology could be their significant growth rate and survival in severe environmental conditions due to their distinct and unique metabolic pathways as well as active defensive mechanisms. In this review, we elaborated on the versatile cyanobacteria applications in different areas of biotechnology. We also emphasized the factors that could impede the implementation to cyanobacteria applications in biotechnology and the execution of strategies to enhance their effective applications.
