Las microalgas y cianobacterias son la nueva plataforma biotecnológica par la producción de diversos metabolitos de interés industrial como carbohidratos, proteínas, lípidos, carotenoides e incluso metabolitos menos comunes como lo son los hidrocarburos y los exopolisacaridos. Una de las especies con la capacidad de producir un amplio espectro de metabolitos es Botryococcus braunii. Esta alga verde colonial posee la peculiaridad de sintetizar hidrocarburos, Exopolisacáridos y otros metabolitos. La presente contribución presenta un panorama bibliométrico de la investigación mundial sobre la producción de B. braunii y sus principales metabolitos de interés para procesos industriales. Los datos de publicaciones científicas durante los últimos 21 años (2000-2021) se obtuvieron de la base de datos SCOPUS© y se filtraron mediante una estrategia de búsqueda sistemática. A partir del análisis se obtuvo un total de 675 documentos científicos enfocados en el aislamiento, producción y mejoramiento de cepas pertenecientes a la especie Botryococcus braunii. De acuerdo con la información obtenida la mayor cantidad de trabajos publicados se han enfocado en la producción y mejoramiento de hidrocarburos tanto para la obtención de biocombustibles. Los principales países que mas han aportado a la investigación de esta especie son Estados Unidos, Japón, China e India; Sin embargo países con alta concentración de biodiversidad como Colombia presentan pocos trabajos con cepas aisladas dentro del territorio nacional. Este análisis bibliométrico permite evidenciar el alto grado de desarrollo obtenido en los últimos 20 años para generar plataformas biotecnológicas para la obtención de. nuevas materias primas para diferentes sectores industriales.

The production of biofuels using wastewater as a microalgae culture medium is a little explored technology, but with potential for success. In order to contribute to the knowledge of these technologies and their technical feasibility for microalgae growth, in this work the Chlorella sp. strain was cultivated in two types of effluents generated in an experimental farm located in eastern Colombia, before and after a biological treatment process. The consumption of the main nutrients that regulate growth and lipid production was evaluated, in order to extract, quantify, characterize and convert them into biodiesel. The results showed that Chlorella sp. growth and lipid production is more favourable in R2 medium of treated water than in R1 medium of raw water, mainly due to phosphorus limitation and higher N-NO3 concentration in R2 compared to R1. In the R2 medium culture, a percentage of 42.54% of long-chain fatty acids was found, which is necessary to obtain a high quality biodiesel. Finally, the best transesterification experiment allowed reaching a fatty acid methyl esters (FAME) percentage of 90.1 ± 2.7%. In general, the results demonstrated the potential viability of using the wastewater generated in the San Pablo farm to produce biomass with lipid content to obtain biodiesel, finding that where the concentration of nutrients, mainly nitrogen, has a great influence on the microalgal metabolism for lipid accumulation.

The use of pesticides in agriculture has ensured the production of different crops. However, pesticides have become an emerging public health problem for Latin American countries due to their excessive use, inadequate application, toxic characteristics, and minimal residue control. The current project evaluates the ability of two strains of algae (Chlorella and Scenedesmus sp.) and one cyanobacteria (Hapalosyphon sp.) to remove excess pesticides and other nutrients present in runoff water from rice production. Different concentrations of wastewater and carbon sources (Na2CO3 and NaHCO3 ) were evaluated. According to the results, all three strains can be grown in wastewater without dilution (100%), with a biomass concentration comparable to a synthetic medium. All three strains significantly reduced the concentration of NO3 and PO4 (95 and 85%, respectively), with no difference between Na2CO3 or NaHCO3 . Finally, Chlorella sp. obtained the highest removal efficiency of the pesticide (Chlorpyrifos), followed by Scenedesmus and Hapalosyphon sp. (100, 75, and 50%, respectively). This work shows that it is possible to use this type of waste as an alternative source of nutrients to obtain biomass and metabolites of interest, such as lipids and carbohydrates, to produce biofuels.
