Cada dia uno mejora , aprende y reflexiona. Aparentemente a llegado el momento de tomar las cosas con calma no porque yo lo quiera sino porque todo tiene una forma de ser, una secuencia de sucesos que deben de ocurrir antes de poder pasar nuevas etapas. Si tuviera que calificar el progreso obtenido en la investigacion en relacion a mis metas a principio del semestre usando una escala de valores del 1-5 yo le otorgaria un 2. Han habido algunas dificultades en cuanto a la caracterizacion usando como metodo la secuenciacion del genes y subunidades variables usadas como herramientas para este fin, por lo se ha integrado otras vias para poder realizar el mismo. Se estara utilando sistemas api asi como tambien se utilizara maquinaria computadorizado detallar y corroborar resultados mediante el estudio del metabolismo de los bioprospectos.
Hay gran jubilo y aires de fiesta al poder decir de forma concreta que el abstract de esta investigacion a sido aceptada para poster presentation durante el 109th General Meeting de la American Society for Microbiology que se celebrara en Phhiladelfia, Pennsylvania. Esta es una importante meta ya que este foro es considerado como el maximo en su tipo nacionalmente, sino INTERNACIONALMENTE, para la difucion de investigacion microbiana. Que no quede duda del potencial investigativo del RUM ya que 8 hemos sido los agraciados en mi laboratorio para poder presentar nuestras investigaciones en el. Espero el apoyo concerniente a un logor como este.
Aqui les presento mi abstract:
Isolation and Characterization of Bioprospects from the Phytotelmata of
the Pitcher plant Nepenthes sp.
Josue G Millan & Carlos Rios-Velazquez PhD
Abstract
Some carnivorous plants such as the genus Sarracenia and Nepenthes have an unusual and specific environment present in their pitchers known as phytotelmata. This aquatic microenvironment could serve as a habitat for bioprospecting microbes to unravel new activities with diverse applications. The main focuses of this project is the isolation and characterization of microbes (bioprospects) from Nepenthes‘ pitchers, and test their biomedical or biotechnological potential. Pitchers’ fluid from Closed (C), Opened (O) and Semi-opened (SO) was collected and spreaded onto enriched solid media with a pH similar to the respective pitcher’s fluid. The samples were incubated at 25°C and 37°C for a week. The pitcher’s fluid analysis showed to be acidic, pH from 4.0 – 5.0. After three days of incubation, there was microbial growth only in the fluid coming from the opened pitchers, suggesting that there was not cultivable endemic microflora in the fluid, at the media and parameters used. The isolates were analyzed microscopically, microbiologically, and physiologically, determining also the optimal pH, temperature, and salt concentration for growth. Three basic morphotypes were found in the sample, with an optimum growth temperature of 25°C and variable pH growth intervals. The morphotypes ranged from spherical, to rod-like, with one of them showing the presence of a stalked or appendance. Genomic DNA extraction of the candidates and preliminary molecular analyses suggest that most of the isolates belong to fungi kingdom. The 18S rDNA, ITS and IGS regions have been amplified to determine their specific classification using sequencing and in silico analysis.
