“…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). Cabe resaltar que la mayor cantidad de publicaciones se concentra en países como Alemania [22][23][24][25]; Australia [26]; Brasil [13,[27][28][29][30]; Chile [31,32]; China [33][34][35][36][37][38][39][40][41][42][43][44]; Colombia [12]; Francia [45][46][47]; India [48][49][50][51][52][53]; Inglaterra [54], Japón [55][56][57][58][59][60][61][62][63][64][65]…”

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.

“…The growth and production of lipids in B. braunii are affected by several factors, such as nutrition, temperature, salinity, pH, CO2, DO and turbidity (Al-Hothaly et al 2016;Jin et al 2016;Concha et al 2018;Cheng et al 2019). Optimum growth conditions result in producing a high amount of biomass, hydrocarbons, chlorophyll, phosphates, proteins carotenoids (Cepák and Přibyl 2018;Uchida et al 2018;Wan et al 2019).…”

Abstract. Nugroho RA, Subagyono DJN, Arung ET. 2020. Isolation and characterization of Botryococcus braunii from a freshwater environment in Tenggarong, Kutai Kartanegara, Indonesia. Biodiversitas 21: 2331-2336. The use of microalgae as an alternative source of oil has gained much attention in recent years. The present study was conducted to isolate and characterize microalgae Botryococcus braunii from a freshwater environment, located in Tenggarong, Kutai Kartanegara, East Kalimantan, Indonesia. B. braunii were cultured and determined their growth in terms of biomass yield and the presence of lipid globules by red Nile staining. Dry biomass, phosphate, and protein content of cultured B. braunii were measured at 3 days of intervals for 24 days. Biomass yield, hydrocarbon, carotenoid, and chlorophyll content were determined at the pH range of 6, 6.5, 7, 7.5, and 8 and various CO2 concentrations. The result showed that B. braunii collected from freshwater in Tenggarong can produce lipid globules. The highest growth of B. braunii was reached at day 15, while the optimal phosphate content was on the 12th day, and the protein was relatively stable during culture. The optimal weight of B. braunii biomass was reached at pH 7 and 4% CO2 and the highest hydrocarbon content was obtained at pH 8 and 4% CO2. The highest chlorophyll and carotenoid contents were obtained 4% CO2. In conclusion, B. braunii collected from Tenggarong was successfully cultured and able to produce lipid globules. The optimal conditions for its growth and production of hydrocarbon, phosphate, protein, chlorophyll, and carotenoid were at pH of 7-8 and 4% CO2.

“…Carbon dioxide (CO 2 ) emissions play an important role in global climate regulation by changing the earth's radiation budget, temperature, meteorology and hydrology (Feng et al, 2008). The main sources of CO 2 emissions are combustion of fossil fuels, such as coal, natural gas and oil, for energy and transportation (Al-Hothaly et al, 2015). Emissions of CO 2 have dramatically increased within the last 50 years and continue to increase by almost 3% each year (Pires et al, 2012).…”

In order to identify a high carbon-sequestering microalgal strain, the physiological effect of different concentrations of carbon sources on microalgae growth was investigated. Five indigenous strains (I-1, I-2, I-3, I-4 and I-5) and a reference strain (I-0: Coccolithus pelagicus 913/3) were subjected to CO 2 concentrations of 0.03-15% and NaHCO 3 of 0.05-2 g CO 2 l-1. The logistic model was applied for data fitting, as well as for estimation of the maximum growth rate (μ max) and the biomass carrying capacity (B max). Amongst the five indigenous strains, I-3 was similar to the reference strain with regards to biomass production values. The B max of I-3 significantly increased from 214 to 828 mg l-1 when CO 2 concentration was increased from 0.03 to 15% (r = 0.955, P = 0.012). Additionally, the B max of I-3 increased with increasing NaHCO 3 (r = 0.885, P = 0.046) and was recorded at 153 mg l-1 (at 0.05 g CO 2 l-1) and 774 mg l-1 at (2 g CO 2 l-1). Relative electron transport rate (rETR) and maximum quantum yield (F v /F m) were also applied to assess the impact of elevated carbon sources on the microalgal cells at the physiological level. Isolate I-3 displayed the highest rETR confirming its tolerance to higher quantities of carbon. Additionally, the decline in F v /F m with increasing carbon was similar for strains I-3 and the reference strain. Based on partial 28s ribosomal RNA gene sequencing, strain I-3 was homologous to the ribosomal genes of Chlorella sp.
