Identificación de los Genes cry en Cepas Mexicanas de Bacillus thuringiensis con Potencial Insecticida

Acta Universitaria (2003)

T. Rosales-Reyes R. Salcedo-Hernández Jorge E. Ibarra José E. Barboza‐Corona

En el presente estudio se determinó la morfología y la composición proteica de los cristales de las cepas LBIT-499 y LBIT-504 de B. thuringiensis, ambas nativas de Guanajuato, México. La primera mostró sólo cristales bipiramidales mientras que la segunda presentó cristales tanto bipiramidales como cúbicos. Estos cristales estuvieron compuestos de proteínas de aproximadamente 130 y 60 kDa, respectivamente. En ambas cepas, además de la LBIT-500 y LBIT-544, se detectó una gran variedad de genes cry1. En éstas últimas se encontraron los genes cry2A y cry2B, en la LBIT- 504 sólo el cry2B y en la LBIT-499 no se detectó ningún cry2.

A fast micromethod for the estimation of nisin activity in a soft cheese

International Journal of Dairy Technology (2019)

Zuleyka S. Oros-Flores Blanca E. García‐Almendárez José E. Barboza‐Corona Rubén Salcedo‐Hernández

The British Standard protocol currently used to determine the nisin concentration in cheese requires the manipulation of a 40 g sample involves two critical points, pH adjustment and heating/cooling. In this work, we developed a fast micromethod that permits the manipulation of 0.2 g cheese, substitutes the use of 0.02N HC l by 50 mM citric acid and facilitates the handling of many samples in reduced time, and with increased efficiency/yield. This change keeps the pH stable at ~3.4, enough to sidestep the pH adjustment, and nisin antimicrobial activity was stable at boiling temperatures.

Molecular Detection and Sensitivity to Antibiotics and Bacteriocins of Pathogens Isolated from Bovine Mastitis in Family Dairy Herds of Central Mexico

BioMed Research International (2015)

Ma. Fabiola León‐Galván José E. Barboza‐Corona Alma Arianna Lechuga-Arana Mauricio Valencia-Posadas Daniel D. Aguayo

Thirty-two farms (n=535cows) located in the state of Guanajuato, Mexico, were sampled. Pathogens from bovine subclinical mastitis (SCM) and clinical mastitis (CLM) were identified by 16S rDNA and the sensitivity to both antibiotics and bacteriocins of Bacillus thuringiensis was tested. Forty-six milk samples were selected for their positive California Mastitis Test (CMT) (≥3) and any abnormality in the udder or milk. The frequency of SCM and CLM was 39.1% and 9.3%, respectively. Averages for test day milk yield (MY), lactation number (LN), herd size (HS), and number of days in milk (DM) were 20.6 kg, 2.8 lactations, 16.7 animals, and 164.1 days, respectively. MY was dependent on dairy herd (DH), LN, HS, and DMP<0.01, and correlations between udder quarters from the CMT were around 0.49P<0.01. Coagulase-negative staphylococci were mainly identified, as well as Staphylococcus aureus , Streptococcus uberis , Brevibacterium stationis , B. conglomeratum , and Staphylococcus agnetis . Bacterial isolates were resistant to penicillin, clindamycin, ampicillin, and cefotaxime. Bacteriocins synthesized by Bacillus thuringiensis inhibited the growth of multiantibiotic resistance bacteria such as S. agnetis , S. equorum , Streptococcus uberis , Brevibacterium stationis , and Brachybacterium conglomeratum , but they were not active against S. sciuri , a microorganism that showed an 84% resistance to antibiotics tested in this study.

Synthetic biology in Mexico: Brief history, current landscape, and perspectives towards a bio‐based economy

Engineering Biology (2025)

Uriel E. Barboza‐Pérez Ma. de Lourdes Pérez-Zavala José E. Barboza‐Corona

Abstract Synthetic biology (SynBio) makes biology easier by leveraging engineering principles and other disciplines to design and construct biological systems with novel or enhanced functions. SynBio has led to the development of more sustainable biotechnological innovations that are in harmony with the environment, aiding the shift from a traditional to a bio‐based economy. Mexico has made significant advancements in biotechnology in academia and industry, but progress in engineering biology has been different. Nevertheless, several initiatives, mainly supported by the participation of Mexican International Genetically Engineered Machine (iGEM) teams in the jamboree, have contributed to the interest of SynBio. This review provides a brief overview of the significant role of the iGEM competition and the current landscape of synthetic biology in Mexico, including educational and citizen science initiatives, as well as an overview of Synbio research and the industrial landscape. Additionally, a brief description of the current laws governing biotechnology in the country is provided. Finally, we highlight the challenges, opportunities and perspectives for the development of synthetic biology and the potential that Mexico has for a biologically based economy.

Agave: a natural renewable resource with multiple applications

Journal of the Science of Food and Agriculture (2020)

Ma. de Lourdes Pérez-Zavala Juan Cristóbal Hernández Arzaba Dennis K. Bideshi José E. Barboza‐Corona

Abstract Agaves are a group of succulent plants that thrive in arid or semiarid environments. Indeed, genes associated with their resilience are a potential resource for genetic engineering of other agronomically important crops grown in adverse climates. Agave is mainly used for the production of distilled (spirits) and non‐distilled alcoholic beverages, including tequila, mezcal, bacanora, raicilla, and pulque, all of which have special connections to Mexican history and culture, and contribute to the Mexican economy. In recent years, there has been growing interest to maximize the use of agave plant materials for other purposes, as the bulk of their biomass pre‑ and post‐production is wasted. In traditional practice, during the passage from fields to factories, only agave cores are used, and the leaves and bagasse are not always harnessed. To place this in perspective, during the period from 2010 to 2019, 2674.7 × 10 6 L of tequila was produced in Mexico, which required 9 607 400 tons of agave cores. This generated approximately the same amount of leaves and 3 842 960 tons of bagasse. The economic base of agave plants can be expanded if expended biomass could be transformed into products that are useful for applications in food, forage, ensilage, agriculture, medicine, energy, environment, textiles, cosmetics, and esthetics. This review focuses on the current utility of agave plants, as well as our perspective for future studies and uses of this formidable plant. © 2020 Society of Chemical Industry
