“…Although B. braunii has some characteristics of Volvocales, like the extracellular matrix (ECM) and coenobium-like structure (Figure 8) [32,38], multiple fission has not been reported in B. braunii. Due to the production of useful hydrocarbons, most of the reports on the factors influencing the growing of B. braunii have been focused on strategies to increase lipid production [104][105][106][107][108]. Probably, all these procedures modify the natural cell cycle of the alga and up to now, all races have been assumed to have binary fission [14,15,25].…”

Botryococcus braunii produce liquid hydrocarbons able to be processed into combustion engine fuels. Depending on the growing conditions, the cell doubling time can be up to 6 days or more, which is a slow growth rate in comparison with other microalgae. Few studies have analyzed the cell cycle of B. braunii. We did a bioinformatic comparison between the protein sequences for retinoblastoma and cyclin-dependent kinases from the A (Yamanaka) and B (Showa) races, with those sequences from other algae and Arabidopsis thaliana. Differences in the number of cyclin-dependent kinases and potential retinoblastoma phosphorylation sites between the A and B races were found. Some cyclin-dependent kinases from both races seemed to be phylogenetically more similar to A. thaliana than to other microalgae. Microscopic observations were done using several staining procedures. Race A colonies, but not race B, showed some multinucleated cells without chlorophyll. An active mitochondrial net was detected in those multinucleated cells, as well as being defined in polyphosphate bodies. These observations suggest differences in the cell division processes between the A and B races of B. braunii.

“…The improvement in biomass production is often correlated with the increase in photosynthetic activity due to an increment in the expression of photosynthetic enzymes and chlorophyll content [ 69 , 71 , 72 , 73 , 74 , 75 ]. Concerning the accumulation of lipids, in several studies, the upregulation of enzymes related to the biosynthesis of fatty acids, such as acetyl-CoA carboxylase (ACCase), an acyl carrier protein (ACP), malonyl-CoA: ACP-transacylase (MCTK), and fatty acid desaturase (FAD) was reported [ 73 , 74 , 76 , 77 , 78 ].…”

Development of Microalgae Biodiesel: Current Status and Perspectives

Microalgae are regarded as a promising source of biodiesel. In contrast with conventional crops currently used to produce commercial biodiesel, microalgae can be cultivated on non-arable land, besides having a higher growth rate and productivity. However, microalgal biodiesel is not yet regarded as economically competitive, compared to fossil fuels and crop-based biodiesel; therefore, it is not commercially produced. This review provides an overall perspective on technologies with the potential to increase efficiency and reduce the general costs of biodiesel production from microalgae. Opportunities and challenges for large-scale production are discussed. We present the current scenario of Brazilian research in the field and show a successful case in the research and development of microalgal biodiesel in open ponds by Petrobras. This publicly held Brazilian corporation has been investing in research in this sector for over a decade.

“…El análisis correspondiente de los documentos recopilados entre los años 2000 a 2021, se encontraron 675 documentos repartidos entre artículos científicos (561), conference papers (52), reviews (43), capítulos de libros (11) entre otros (Figura 1). Si bien durante los primeros 10 años (2000-2010) las publicaciones en torno a esta microalga no superaron la barrera de los 30 documentos por año, en el año 2011 se puede apreciar un crecimiento exponencial (de 20 a mas de 50 documentos anuales), seguido de un nivel constante de publicaciones anuales hasta una reducción significativa en los últimos 2 años (2020-2021).…”

Las microalgas son microorganismos fotosintéticos los cuales pueden ser eucariotas (algas) o procariotas (cianobacterias) y pueden estar presentes en todos los hábitats de la tierra. Este artículo ofrece una descripción bibliográfica sobre análisis técnicos en la producción industrial de los principales metabolitos extraídos de Botryococcus braunii con el objetivo de analizar, determinar e identificar los avances científicos para la utilización de esta alga como un recurso potencial, por medio de una recopilación bibliométrica de 20 años sobre artículos de investigaciones demostrando gran interés en el campo de las microalgas. Se ha realizado este trabajo con el propósito de averiguar los estudios en el área de la microalga Botryococcus braunii y sus aplicaciones industriales, también determinar los principales metabolitos como hidrocarburos, exopolisacáridos, carotenoides, proteínas, en el aprovechamiento de procesos industriales como materiales, alimentos, productos farmacéuticos, nanopartículas y biocombustibles. Debido a sus vías metabólicas particulares, su adaptabilidad fisiológica y su uso en sistemas de cultivo avanzados, existe un gran potencial para producir sustancias químicas de alto valor a partir de cepas de Botryococcus braunii.
