“…There are few studies in the literature about incorporation of microorganisms in electrospun nanobers. [23][24][25][26] For instance, Greque de Morais et al 24 produced thin bead-free nanobers from Spirulina sp. biomass as extracellular matrices for stem cell culture and future treatment of spinal chord injury.…”

A contaminant resistant Lysinibacillus sp. NOSK was isolated from a soil sample and its Reactive Black 5 (RB5) and Cr(VI) removal efficiencies were investigated as a function of changes in the initial pH values, temperature, static/shaking conditions, reactive dye and Cr(VI) concentrations. In this study, an electrospun polysulfone nanofibrous web (PSU-NFW) was found to be effective in attachment of bacterial cells. Bacteria attached PSU-NFWs (bacteria/PSU-NFW) have shown highly efficient removal of RB5, as 99.7 AE 0.9% and 35.8 AE 0.4% for the pristine PSU-NFW. Moreover, the highest Cr(VI) removal efficiencies measured were 98.2 AE 0.6% for bacteria attached PSU-NFW and 32.6 AE 0.6% for the pristine PSU-NFW. Simultaneous removal of RB5 and Cr(VI) were also investigated. Reusability test results indicate that, bacteria/PSU-NFW can be reused for at least 7 cycles with 28.1 AE 0.6% and 66.7 AE 0.8% removal efficiencies for RB5 and Cr(VI), respectively.

Environmental changes that have occurred due to the use of fossil fuels have driven the search for alternative sources that have a lower environmental impact. First-generation biofuels were derived from crops such as sugar cane, corn and soybean, which contribute to water scarcity and deforestation. Second-generation biofuels originated from lignocellulose agriculture and forest residues, however these needed large areas of land that could be used for food production. Based on technology projections, the third generation of biofuels will be derived from microalgae. Microalgae are considered to be an alternative energy source without the drawbacks of the first- and second-generation biofuels. Depending upon the growing conditions, microalgae can produce biocompounds that are easily converted into biofuels. The biofuels from microalgae are an alternative that can keep the development of human activity in harmony with the environment. This study aimed to present the main biofuels that can be derived from microalgae.

“…Because of their anti-inflammatory properties, microalgal biomass is being considered for applications in tissue engineering for the development of scaffolds, for use in the reconstitution of organs and tissues [58,59]. This is an important application for humans, especially in patients with burns in which the skin was completely lost [60].…”

Pharmaceutically valuable products from microalgae and its industrial commercialization today is still in its infancy and can be seen as a gateway to a multibillion dollar industry. Microalgae generally grow autotrophically and are ubiquitous in nature. They represent a major untapped resource of genetic potential for valuable bioactive agents and fine biochemical. This proven ability of microalgae to produce these compounds places these microorganisms in the biotechnological spotlight for applications and commercialization as in the pharmaceutical industry. The production of microalgal metabolites, which stimulate defense mechanisms in the human body, has spurred intense study of the application of microalgal biomass and products thereof in various food preparations, pharmacological and medical products. There is, therefore, a huge scope for further study of the identified algal compounds and their activities in the treatment and prevention of various diseases, in addition to an ongoing search for other, as yet undetected, metabolites.
