“…The CS–PEI–GLA C 1s spectrum shows four peaks at 285.3 and 286.5, attributed to the C–C and C–NH 2 bonds from amine groups from both chitosan and PEI, and at 286.7 and 288.9 attributed to C–OH and CO bonds from chitosan, respectively. 4,56,87 The CS–PEI–GLA N 1s spectrum presented peaks at 400.94 for –NH– and at 398.87 for –N. Table 4 shows the contribution of each functional group.…”

Las microalgas se destacan por su capacidad de adaptarse a diferentes medios de cultivo, participación en captura de CO2 y productos de interés biotecnológico cómo biocombustibles, proteínas, biofertilizantes, suplementos alimenticios, pigmentos, entre otros. Se han trabajado diferentes tipos de estrés como variación del pH, deficiencia de nutrientes, estrés salino, cambios en la temperatura y alta irradiancia con el fin de aumentar la producción de metabolitos aplicado a diferentes industrias; sin embargo, la demanda de los productos biotecnológicos se ha incrementado ante las necesidades de la población, por lo que el uso de tecnologías de modificación genética ha surgido como una alternativa durante la última década gracias a la capacidad y eficiencia que muestran los métodos como mutagénesis aleatoria, supresión de genes y crispr-cas9. Se propone como objetivo conocer la aplicación del crispr-cas9 en microalgas relacionado con la obtención de productos biotecnológicos de interés industrial. Se determinó que esta tecnología aplicada en las microalgas con uso industrial incrementa la obtención de productos de interés biotecnológico como lípidos, carotenoides, proteínas y enzimas recombinantes.

Microalgae technology is a viable solution for environmental conservation (carbon capture and wastewater treatment) and energy production. However, the nutrient cost, slow-kinetics, and low biosorption capacity of microalgae hindered its application. To overcome them, algal-biochar (BC) can be integrated with microalgae to treat textile wastewater (TWW) due to its low cost, its ability to rapidly adsorb pollutants, and its ability to serve as a nutrient source for microalgal-growth to capture CO2 and biodiesel production. Chlorella vulgaris (CV) and algal-BC were combined in this work to assess microalgal growth, carbon capture, TWW bioremediation, and biodiesel production. Results showed the highest optical density (3.70 ± 0.07 OD680), biomass productivity (42.31 ± 0.50 mg L−1 d−1), and dry weight biomass production (255.11 ± 6.01 mg L−1) in an integrated system of CV-BC-TWW by capturing atmospheric CO2 (77.57 ± 2.52 mg L−1 d−1). More than 99% bioremediation (removal of MB-pollutant, COD, nitrates, and phosphates) of TWW was achieved in CV-BC-TWW system due to biosorption and biodegradation processes. The addition of algal-BC and CV microalgae to TWW not only enhanced the algal growth but also increased the bioremediation of TWW and biodiesel content. The highest fatty acid methylesters (biodiesel) were also produced, up to 76.79 ± 2.01 mg g−1 from CV-BC-TWW cultivated-biomass. Biodiesel’s oxidative stability and low-temperature characteristics are enhanced by the presence of palmitoleic (C16:1) and linolenic (C18:3) acids. Hence, this study revealed that the integration of algal-biochar, as a biosorbent and source of nutrients, with living-microalgae offers an efficient, economical, and sustainable approach for microalgae growth, CO2 fixation, TWW treatment, and biodiesel production.
