    Caracterización de litologías del noreste de México y su utilización como análogos en pruebas de desplazamiento de hidrocarburo para recuperación mejorada. por Chávez García, Angelo Iván

    Publicado 2017
    “…ABSTRACT: The study of carbonate reservoirs is of great importance in our country because most of the production of hydrocarbons comes from these deposits, which are difficult to produce because they have complex lithologies and structural heterogeneities, therefore, the information of said deposits are scarce and only a small number of wells have cores due to the difficulty and cost of extracting such cores; it is for this reason that the use of analogues of carbonate rocks, in particular the storage rocks of the Lower Cretaceous of the Cantarell Complex, is proposed. …”

    Aislamiento y selección de cepas mutantes de Hirsutella citriformis inducidas por el agente químico: metanosulfonato de etilo (EMS). por Cruz Juárez, Georgina

    Publicado 2017
    “…Techniques such as biphasic culture on different low-cost substrates (sorghum, rice and oats) were evaluated to obtain the highest conidia production that would be used in classical mutagenesis with the chemical agent ethyl methane sulfonate (EMS) which has been successfully used to introduce changes of a single base in the DNA, a mutation protocol was established varying times and concentrations for the obtaining of mutant strains, which were characterized based on radial growth, production of conidia and speed of germination in media as PDA and PDA with yeast extract. …”
