“…This type of biosorption is dependent on cell metabolism and can only occur in living cells. Metal precipitation can actually occur both in solution and at the cell's surface (Garbowski et al 2020a). If, in the presence of metals, microorganisms produce compounds that promote the precipitation process, the process will be dependent on the cell's metabolism.…”

The use of materials of natural origin for the adsorption of heavy metal ions from aqueous solutions has gained attention in recent years among the scientific community. This is explained by the fact that nickel compounds, due to severe health consequences, are considered to be among the most dangerous to the environment. This article reviews the results of studies on the use of biosorbents for purification of aqueous solutions from nickel ions, and then attempts to classify them according to their origin. The characteristics of materials and their sorption capacity have been compared, and the removal mechanisms identified of which chemisorption and ion exchange are considered to be the most common. From the analyses, a major trend is the use of biomass; however, biosorbents from other groups also continue to attract the interest of researchers. Conducting laboratory studies can help select materials with high efficiency. The highest sorption capacity values for the materials in each group were: for waste products 56 mg Ni·g−1 (olive stone), for peat 61 mg Ni·g−1, for miscellaneous 225 mg Ni·g−1 (microbial flocculant GA1), for biomass 286 mg Ni·g−1 (Plantanus orientalis bark) and for composites/modified materials calcinated eggshells 769 mg Ni·g−1 (calcinated eggshells). However, for some materials the sorption phenomenon may be accompanied by precipitation in the presence of hydroxides, which significantly affects the sorption capacity achieved. There is a need to transfer these experiments to an industrial scale so as to verify their applicability. In such industrial scale applications, attention should be paid not only to the effectiveness of the material, but also to its availability, price, and ease of use, as well as the effect of the biosorbent in terms of changing the quality parameters of the aquatic environment.

“…Natural biomass-based scaffold materials present more options as well. The biomass-derived natural carriers, referred to as a bio-matrix, usually comprise loofah [ 90 , 96 , 97 ], corn cob [ 61 ], pine bark [ 91 , 98 ], sugarcane bagasse [ 99 ], or cotton cloth pieces [ 100 ]. The open network of fibrous support in these natural materials allows them to quickly contact microalgal cells and then establish a robust immobilization system [ 90 ].…”

“…This has the ability to hold biomass, remove nutrients, and make harvesting more feasible than suspended systems. Furthermore, this type of application may not provide for system agitation and consequently lower energy consumption [5,115,116]. Biofilms are consortia of microalgae and bacteria trapped in a matrix in aquatic environments [117].…”

“…However, these materials are expensive, synthetic and nonbiodegradable, and consequently potentially harmful to the environment. Garbowski [115] evaluated the feasibility of using pine bark as an alternative, biodegradable and low-cost material. The results demonstrated the effectiveness of using pine bark in the treatment of wastewater and in immobilizing algae on pine bark, facilitating its separation and then the harvesting of algal biomass.…”

A Review about Microalgae Wastewater Treatment for Bioremediation and Biomass Production—A New Challenge for Europe

et al. 2021

Microalgae have received much attention in the last few years. Their use is being extended to different fields of application and technologies, such as food, animal feed, and production of valuable polymers. Additionally, there is interest in using microalgae for removal of nutrients from wastewater. Wastewater treatment with microalgae allows for a reduction in the main chemicals responsible for eutrophication (nitrogen and phosphate), the reduction of organic substrates (by decreasing parameters such as BOD and COD) and the removal of other substances such as heavy metals and pharmaceuticals. By selecting and reviewing 202 articles published in Scopus between 1992 and 2020, some aspects such as the feasibility of microalgae cultivation on wastewater and potential bioremediation have been investigated and evaluated. In this review, particular emphasis was placed on the different types of wastewaters on which the growth of microalgae is possible, the achievable bioremediation and the factors that make large-scale microalgae treatment feasible. The results indicated that the microalgae are able to grow on wastewater and carry out effective bioremediation. Furthermore, single-step treatment with mixotrophic microalgae could represent a valid alternative to conventional processes. The main bottlenecks are the large-scale feasibility and costs associated with biomass harvesting.
