For some time, microalgae cultures have been studied in municipal wastewater bioremediation processes. It has been shown that they are an efficient alternative to remove pollutants from them, in this type of effluent the main pollutants are nitrogen and phosphorus, which are assimilated by microalgae for their growth, in the form of ammonium and or...

Tópicos selectos de ingeniería y ciencias ambientales Tópicos selectos de ingeniería y ciencias ambientales presenta diversos avances ubicados en tres categorías del conocimiento. Busca encaminar el manejo de los recursos hídricos, prevenir la contaminación del agua, revisar los lineamientos portuarios y vigilar las mareas en el Golfo de México par...

La capacidad de adaptación de las microalgas es de vital importancia para su cultivo en diferentes ambientes y sistemas, en este trabajo utilizamos la clorofita Coelastrella sp., para biorremediar un agua residual denominada “nejayote”, la cual proviene del proceso de elaboración de tortillas de maíz, por tanto, el efluente tiene alta carga orgánic...

En México existe un matiz de contextos en las poblaciones, pues mientras en las ciudades logramos percibir el desarrollo y avance tecnológico, en zonas rurales es complicado que estos avances puedan llegar, y no nos referimos a tecnologías de la comunicación, sino a aquellas que se relacionan con el bienestar social y la búsqueda de un desarrollo i...

Antecedentes: Las microalgas y cianobacterias son fuente potencial de nuevas aplicaciones con actividad biológica. En nuestro país la investigación de aplicaciones de estos organismos es incipiente aún. Objetivo: Probar el potencial de algunas especies de microalgas y cianobacterias como aglutinantes de eritrocitos (presencia de lectinas) y bacter...

The production of microbial biomass can be affected by the composition of the culture medium, including the content of salts and there is little information in terms of the NaCl concentration. Therefore, in this study, the effect of the addition of different NaCl concentrations (0.0, 2.0, 2.5, and 3.0 g L-1) in a Jourdan medium was evaluated on cel...

Background Due to the problems we face today, such as wastewater pollution of aquifers and climate change, it is necessary to search for environmental solutions that help us minimize this problem. An alternative solution might be the cultivation of microalgae that are efficient in the purification of wastewater, removal of greenhouse gases and prod...

Resumen-La espirulina (Arthrospira máxima) es conocida desde la época de los aztecas como "Tecuitlatl", formaba parte de la dieta básica de esa civilización. En años recientes, esta alga es reconocida como el alimento del futuro gracias a sus propiedades nutrimentales, destacando su alto contenido en proteína del 55-70% en peso seco, fácil digestió...

Macroalgae synthesize molecules that may be toxic to other organisms. These molecules are synthesized as a defense strategy against herbivores. It has been proven that the synthesis process is directed by several physiological, chemical and even spatial-temporal variables. The purpose of this study was to determine whether the complexity of the hab...

Resumen El maíz azul contiene más proteínas y una menor cantidad de almidón que el maíz blanco; mayor cantidad de antocianinas y compuestos fenólicos que lo hacen más resistente a plagas y lo protegen del estrés biótico y abiótico. Entre las prácticas agronómicas que se realizan para su cultivo se encuentra la aplicación de fertilizantes químicos,...

En muchos países de los llamados “economías emergentes” el mosaico social es muy heterogéneo, presentándose comunidades con un nivel de desarrollo relativamente alto y estable. Sin embargo, también existen poblaciones con limitaciones muy graves de extrema pobreza como son la ausencia de piso firme en las casas, ausencia de drenaje, carencia de ser...

Harmful algal blooms (HABs) have recently attracted the attention of local people, authorities, and scientists. This is because of the important and negative consequences they have on the environment, economy, and health. One aspect of this interest is the possibility of knowing the mechanisms that trigger this phenomenon and therefore being able t...

The use of microalgae for bioremediation of wastewater and organic leachates has been the subject of numerous investigations due to its capacity to remove significant amounts of nitrates and phosphates. In addition, to generate microalgal biomass with added value for its commercial interest. In this work we studied the removal of N and P municipal...

This paper reviews some of the most important aspects of microalgae as a potential source for biodiesel production. Microalgae are photosynthetic microorganisms that can grow rapidly in a variety of environments because of their unicellular or multicellular structure depending on the species. They have the advantage of self-reproduction using solar...

The Carpintero Lagoon is a wetland estuary, with 90.4ha of water surface, located in the center of the city of Tampico, Tamaulipas, Mexico, between 22 degrees 15 - 22 degrees 14'N and 97 degrees 52' -97 degrees 52'W. Currently it contains several species under protection. The aim of this study was to analyze the composition and variation of phytopl...

Abstract Sustainable alternative sources of protein and lipids have become a priority due to asymptotic limitations of production of traditional crops under the burden of exponential population growth, climate change, and energy resource limits. Microalgae and cyanobacteria contain substances that have high biological value, such as polyunsaturated...

During a phytoplankton survey, non-motile (cyst-like) cells were isolated and cultured from the tropical Mexican Pacific, which belong to the thecate dinoflagellate Vulcanodinium rugosum Nézan et Chom é rat, recently described from the Mediterranean and recently identified as a source of pinnatoxins in Australia, New Zealand, and Japan. Motile cell...

Some microalgae are economically important in Mexico and the world because they can be potentially toxic. Algal explosive population growths are named harmful algal blooms and are frequently recorded in Mexico. The authors set up potentially toxic microalgae cultures from the Gulf of Mexico (Garrapatas tideland, Barberena river, Carpintero lagoon i...

Resumen Se aislaron microalgas del Lago de Catemaco, Veracruz, utilizando diferentes técnicas y se establecieron cultivos utilizando medios tales como el F/2, Provasoli y el fertilizante foliar Bayfoland forte. Estos cultivos no axénicos, "semi-continuos" se mantuvieron con ciclo de 12:12, a 20 ± 1°C y 167 mol m-2 s-1. Se determinaron 17 taxa infr...

A phylogenetic analysis of the Prorocentrum species is presented, that includes the sequences of the large and small ribosomal RNA subunits from 19 cultures from 13 of the 20 species reported in the Pacific coast of Mexico; the results showed that P. micans, P. gracile and P. mexicanum were the closest of species, that planktonic may be more recent...

Abstract – The morphology of the bloom-forming or potentially toxic marine planktonic dinoflagellates Heterocapsa pygmaea (recorded here for the first time in Mexico) and Protoceratium reticulatum was studied based on clonal, non-axenic, “semicontinuous” cultures isolated from Mexican Pacific samples, using light-, scanning- and transmission electr...
