“…Algal cells take in As(V) through phosphate transporters due to the similar properties of As(V) and Pi, and numerous experimental data support a competition between them for intracellular transport. Likewise, phosphate concentration also affects the accumulation, biotransformation (i.e., As(III) oxidation), and excretion of As species [104,105].…”

Arsenic (As) is quite an abundant metalloid, with ancient origin and ubiquitous distribution, which represents a severe environmental risk and a global problem for public health. Microbial exposure to As compounds in the environment has happened since the beginning of time. Selective pressure has induced the evolution of various genetic systems conferring useful capacities in many microorganisms to detoxify and even use arsenic, as an energy source. This review summarizes the microbial impact of the As biogeochemical cycle. Moreover, the poorly known adverse effects of this element on eukaryotic microbes, as well as the As uptake and detoxification mechanisms developed by yeast and protists, are discussed. Finally, an outlook of As microbial remediation makes evident the knowledge gaps and the necessity of new approaches to mitigate this environmental challenge.

“…Microalgae isolated from peat swamps showed excellent performance with a faster growth time of 10 days and higher biomass [7]. The use of microalgae has a high value of photosynthetic conversion efficiency compared to other photosynthetic organisms [8]. Microalgae also have the ability to thrive in diverse ecosystems [9].…”

Microalgae have the ability to remove nutrients, heavy metals, and pollutants in the form of organic substances. Thus, it is expected that the use of microalgae can reduce pollutant levels in contaminated rivers. This study aims to reduce the concentration of pollutants in the Martapura river contaminated with industrial waste by utilizing microalgae. The maximum microalgal growth was obtained on day 4 with a nutritional variation of 5.25 mL as the concentration was 0.0115 g/L. The decrease in the level of pollutants occurred during the treatment with a decrease in sulfate levels from 18.9 mg/L to 11 mg/L. The amount of cadmium decreased from 0.0014 mg/L to an undetectable point. On the other hand, the iron content dropped quite drastically from 1.8 mg /L to 0.8 mg/L.
