Lactic acid bacteria (LAB) are able to produce a number of metabolites with antimicrobial ability. Bacteriocines are a group of biological compounds produced by these microorganisms that may be applied to extend food shelf-life. These peptides are active against Gram positive bacteria, their inhibition spectra includes several toxic and infectious...
The genus Fomitiporia was described by Murrill (1907) and included 17 species with basidiomata perennial and resupinate, hymenophore poroid, context brown color and the basidiospores globoses and hyaline. This genus was considered as a synonym of Fomes, Poria or Phellinus, however, today, several authors have confirmed the delimitation of the...
A morphometric (n = 776) and karyotypic (n = 76) revision of Osgoodomys banderanus, based on the analysis of specimens from Mexico and U. S. A. collections; they proceed from the whole distribution area of the species. Statistical analysis of 14 morphometric characters does not show any differences between O....
Se analizan y describen los caracteres utilizados en la descripción de las especies del género Hydrolithon (Corallinales, Rhodophyta) lo que evidencia la diferencia e inconstancia de su uso a largo de las investigaciones que publican los registros para nuestro país desde 1960. Con la información obtenida se reevalúan estos caracteres...
In the genus Tectaria, about 200 species are cited which are distributed in southwest Asia and the Pacific islands; for the Neotropics there are 25-30 species, especially in South America. The systematics of the genus Tectaria has been built mainly under a morphological approach. However, the high phenotypic plasticity of...
El actual conocimiento de la distribución y abundancia del grupo de peces pertenecientes a la familia Lutjanidae, conocidos como pargos, en diversos cuerpos acuáticos parece ser incompleto. Entre los cuerpos acuáticos en que habitan los pargos están las lagunas costeras, ecosistemas que utilizan para la crianza y el reabastecimiento de...
