HEK293 producing the extracellular domain HER1: Full datasets of continuous fermentation process and metabolites analysis.

The data for provide evidences of the multi steady state of the human cell line HEK 293 was obtained from 2 L bioreactor continuous culture. A HEK 293 cell line transfected to produce soluble HER1 receptor was used. The bioreactor was operated at three different dilution rates in sequential manner. Daily samples of culture broth were collected, a total of 85 samples were processed. Viable cell concentration and culture viability was addressing by trypan blue exclusion method using a hemocytometer. Heterologous HER1 supernatant concentration was quantified by a specific ELISA and the metabolites by mass spectrometry coupled to a liquid chromatography. The primary data were collected in excel files, where it was calculated the kinetic and other variables by using mass balance and mathematical principles. It was compared the steady states behavior each other's to find out the existence of steady states' multiplicity, taking into account the stationary phase with respect to the cell density (which means its coefficient of variation is less than 20 %). From the metabolic measurements by using Liquid Chromatography coupled to mass spectrometry (LC-MS), it was also built the data matrix with the specific rates of the 76 metabolites obtained. The data were processed and analyzed, using multivariate data asssnalysis (MVDA) to reduce the complexity and to find the main patterns present in the data. We describe also the full data of the metabolites not only for steady states but also in the time evolution, which could help others in terms of modeling and deep understanding of HEK293 metabolism, especially under different culture conditions.

Producción y caracterización de las lipasas de Aspergillus niger y A. fumigatus / Production and characterization of lipases from Aspergillus niger and A. fumigatus

Se investaron 12 microorganismos productores de lipasas, para lo cual de utilizaron cepas de bacterias, hongos y levaduras desarrolladas en aceite de oliva 2(por ciento) como fuente de carbono. Se apreció la actividad lipolítica y se estudiaron las características cinéticas de las lipasas extracelulares expresadas por los mejores productores, Aspergillus niger y A. fumigatus. Ambos microorganismos se analizaron en presencia de diferentes fuentes de carbono para precisar la más adecuada para la síntesis de la enzima...(AU)
