“…A microalga Chlorella vulgaris é amplamente encontrada nos ambientes de água doce, também tem sido isolada de águas de enseadas marinhas e águas salobras dos estuários (González et al, 2013;Darienko et al, 2019). Nesse estudo, a espécie mostrou facilidade de aclimatação e rápido crescimento (Li et al, 2016;Wang et al, 2018) confirmando ser uma boa ferramenta para avaliação da toxicidade aguda e crônica (Costa et al, 2008).…”

A toxicidade aquática de ingredientes ativos farmacêuticos (IFAs) e medicamentos é pouco explorada na literatura. A nevirapina (NVP) é um antirretroviral, inibidor não nucleosídeo da enzima transcriptase reversa. Este estudo avaliou a toxicidade aquática desse IFA isolado e como um medicamento à base de NVP. Para isso, foram analisados os efeitos sobre a viabilidade dos organismos aquáticos Chlorella vulgaris, Artemia salina e Aliivibrio fischeri. Foram aplicados os testes de inibição do crescimento por 72 h para a microalga C. vulgaris, de mortalidade por 24 h para o microcrustáceo A. salina e o de inibição da bioluminescência por 15 min para a bactéria A. fischeri. O modelo estatístico de dose-resposta não paramétrico log-logístico foi utilizado para obter as concentrações efetivas (CE) de 50% e 10% para a NVP isolada e para o medicamento. Constatou-se que a NVP isolada afetou a viabilidade das três espécies estudadas, porém, o medicamento à base de NVP não foi tóxico para A. salina. Ressalta-se que a CE50% de NVP diferiu estatisticamente entre o IFA e o medicamento para A. fischeri e A. salina. Observou-se também que há uma estreita faixa de concentração entre o aparecimento dos primeiros efeitos observáveis e dos efeitos tóxicos de NVP nessas espécies. Isso reforça a importância do estudo e do controle de lançamento desse IFA no ambiente. Por fim, concluiu-se que é possível implementar o monitoramento da toxicidade ambiental de micropoluentes na rotina industrial, utilizando testes de toxicidade padronizados e economicamente acessíveis, que oferecem rapidez e praticidade na análise de efluentes.

“…(Wang et al, 2016) and I. galbana Parke (Li et al, 2021). ALE has been used in a trouble-shooting role in the utilization of municipal secondarytreated wastewater (Osundeko et al, 2014), sludge extracts (Wang et al, 2018), and synthetic wastewater (Rezaei et al, 2019) as a nutrient source, and can improve the removal ability of microalgae by through metabolic selection. In conclusion, ALE is suitable for use in microalgae-based wastewater treatment and cultivation without, or with reduced, dilution.…”

“…Many research processes have "adaptively evolved" their laboratory microorganisms merely through the inevitable growth or plate inoculation cycle in cell culture. Profiting from the development of proteomics (Wang et al, 2018), transcriptomics (Perrineau et al, 2014b;Li K. et al, 2017;Qi et al, 2017;Zhou et al, 2017;Li X. et al, 2018;Sun et al, 2018a;Cheng et al, 2019;Zhu et al, 2020;Zhang et al, 2021), genomics (Perrineau et al, 2014a;Helliwell et al, 2015;Shin et al, 2017;Rossoni and Weber, 2019;Yu et al, 2020), and metabolomics (Lohbeck et al, 2014;Li X. et al, 2017;Hu et al, 2020), the application of appropriate bioinformatics techniques will contribute to identification of the key mutation mechanisms in ALE (Sandberg et al, 2019).…”

Adaptive laboratory evolution (ALE) experiments are a serviceable method for the industrial utilization of the microalgae, which can improve the phenotype, performance, and stability of microalgae to obtain strains containing beneficial mutations. In this article, we reviewed the research into the microalgae ALE test and assessed the improvement of microalgae growth, tolerance, metabolism, and substrate utilization by ALE. In addition, the principles of ALE and the key factors of experimental design, as well as the issues and drawbacks of the microalgae ALE method were discussed. In general, improving the efficiency of ALE and verifying the stability of ALE resulting strains are the primary problems that need to be solved in future research, making it a promising method for the application of microalgae biotechnology.

“…Microalga Chlorella kessleri could grow at different crude oil concentrations (0.5, 1, and 1.5%), mixotrophically solely and in combination with Anabaena oryzae . Wang et al (2018) argued that the acclimation process is a potential method of wastewater treatment using Chlorella vulgaris. C. vulgaris showed high e ciency of biodegradation under a low concentration of 0.5% and 1% of crude oil.…”

Dhiba port has a strategic location near the Neom project. Various anthropogenic activities contributed to the discharge of heavy metals and oil spill in the aquatic system and caused environmental pollution. Microalgae are the best microorganisms in aquatic conditions which known to be capable of eliminating contaminants. We investigate the heavy metals and hydrocarbons contaminations exhibited in five sites of port. Our aim is to determine the most contaminated sites then using Immobilized and fresh Chlorella vulgaris in bioremediation. The results indicated that Immobilized and fresh C. vulgaris have the capabilities of growing in contaminated seawater and were capable of removing heavy metals completely. Immobilized C. vulgaris is the most efficient in the degradation of hydrocarbons at site one. Overall, Immobilized C. vulgaris is the most effective in removing both heavy metals and hydrocarbon. It is an economic tool due to simplifying harvesting and then retaining for further processing.
