Currently there is a need for new antibiotics with an alternative mode of action and new chemical structures. Bacterial pathogens are gradually becoming more resistant to conventional antibiotics, generating an emergence of infectious diseases and they are becoming a great problem in the field of public health. In this study, seven different isolated bacteria were obtained from offshore seawater and sediment of the Gulf of Mexico from Campeche, Mexico. They were substance producers which inhibit growth of human pathogens like Staphylococcus aureus and Pseudomonas aeruginosa and one of them was a polymer producer on peptone and glucose culture. They were characterized phenotipically by means of morphological techniques and physiologically by conventional tests. Four of them were Gram-positive bacteria and the Scanning Electron Microscope analysis revealed their size between 0.6 - 1.5 µm....

La Asociación Latinoamericana de Volcanología (ALVO) fue fundada el día 7 de noviembre del año 2010 en Manizales, Departamento de Caldas, Colombia (Granados et al., 2015a, b; Rodríguez et al., 2019). Con un grupo reducido de miembros fundadores, la ALVO quedó establecida e inició operaciones con un primer Consejo Directivo que sentó las bases para un camino de colaboración, reflexión y oportunidades en la región latinoamericana. Hoy en día la asociación cuenta con más de 1500 miembros, repartidos en toda la región Latinoamericana. En números aproximados, se registran 540 miembros para la región de Sudamérica Sur (Argentina, Brasil, Bolivia, Chile, Paraguay y Uruguay), 460 para la región de Sudamérica Norte (Colombia, Ecuador, Guyana, Perú, Surinam y Venezuela), 310 para la región de Centroamérica y el Caribe (Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica,...
