Última Maduración y germinación de embriones somáticos de linaloe In vito y Ex vito. Colegio de Postgraduados González Orozco, María Mónica. El linaloe [Bursera linanoe (La Llave) Rzed., Calderón & Medina] es una especie endémica de México con una importancia histórica, cultural y económica. Sin embargo, ha sido expuesta a la sobreexplotación, lo que ha causado una notable disminución en las poblaciones naturales. Por lo que en la presente investigación se evaluó la embriogénesis somática como una vía de propagación mediante el cultivo in vitro. Con el objetivo de mantener la capacidad embriogénica y cuantificar la tasa de multiplicación de tres líneas embriogénicas de linaloe, se evaluó el efecto de diferentes reguladores de crecimiento, fuentes de carbono y otros componentes, durante la maduración y germinación de embriones somáticos, además de evaluar la aclimatación en invernadero. Los...

Ano: 2014 URL: http://hdl.handle.net/10521/2237 Possibility of using apple pomaces in the process of propionic-acetic fermentation Electron. J. Biotechnol. Piwowarek,Kamil; Lipińska,Edyta; Hać-Szymańczuk,Elżbieta. Background: In 2014, apple production in EU countries amounted to 11.8 million tonnes. A constant increase in the production of these fruits will lead to the accumulation of thousands of tonnes of apple pomace (production waste). The amount of industrial apples is the highest - their proportiononthe market is estimated at 50-60%, of which over 95% is processed into juice. The proportion of pomace in the traditional pressing method accounts for 20% offruits used. Results: Analysis of the growth dynamics of wild strain Propionibacterium freudenreichii T82 in micro-cultures using different carbon sources showed that the highest bacterial growth occurs in an environment with fructose and the most intense biosynthesis of metabolites was found in medium...

Background The cattle gastrointestinal tract (GIT) is the main enterohemorrhagic Escherichia coli (EHEC) reservoir. In order to identify nutrients required for the survival or multiplication of EHEC in the bovine GIT, we compared the transcriptomes of the EHEC O157:H7 reference strain EDL933 cultured in vitro in bovine digestive contents (DCs) (rumen, small intestine and rectum) using RNA-sequencing. Results Gene expression profiles showed that EHEC EDL933 activated common but also specific metabolic pathways to survive in the different bovine DCs. Mucus-derived carbohydrates seem important in EHEC nutrition in posterior DCs (small intestine and rectum) but not in rumen content. Additional carbohydrates (xylose, ribose, mannitol, galactitol) as well as...

Rates of nitrogen fixation (measured as acetylene reduction) in the rhizosphere of the seagrass Zostera noltii were highly dependent upon plant photosynthetic activity being significantly stimulated at elevated CO2 concentrations and by light, both in the short-term and over diurnal cycles. Stimulation by light became insignificant when 5 mM sucrose was added to the sediment porewater, indicating that in the absence of added carbon sources, light stimulation was due to direct inputs of plant photosynthate to the rhizosphere. Addition of a range of carbon sources to the rhizosphere sediment stimulated rates of acetylene reduction, with this stimulation being significant for sucrose and lactate. Surprisingly, whilst low additions of ammonium to the sediment...

ABSTRACT The stable carbon isotopic variability and the contributions of autochthonous (sediment microbial biomass, phytoplankton, and periphyton) and allochthonous (soil microbial biomass) sources available to the detritivorous fish Prochilodus lineatus were investigated in three environments of the floodplain of the Upper Paraná River. The isotopic composition of carbon sources and fish varied significantly among the studied environments. The autochthonous resources, represented by the phytoplankton, were the most assimilated by the species, followed by periphyton and sediment microbial biomass. The species used the sources differently in each environment. This study suggests that the inherent characteristics of this area, as well as the size of the...

Exopolysaccharides (EPSs) production was studied by Lactobacillus delbrueckii subsp. bulgaricus (B3, G12) and Streptococcus thermophilus (W22) in the medium containing various carbon sources (glucose, fructose, sucrose or lactose). For all the strains, glucose was the most efficient carbon source and B3, G12 and W22 strains produced 211, 175 and 120 EPS mg/L respectively. Also, the influence of different concentrations of glucose (5,10,15,20,25,30 g/L) on EPS production and growth was studied. The results indicated that EPS production and growth were stimulated by the high glucose concentration (30 g/L).

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-89132008000300019 Evaluation of cytochrome P-450 concentration in Saccharomyces cerevisiae strains BJPS Matuo,Míriam Cristina Sakuragui; Kikuchi,Irene Satiko; Pinto,Terezinha de Jesus Andreoli. Saccharomyces cerevisiae has been widely used in mutagenicity tests due to the presence of a cytochrome P-450 system, capable of metabolizing promutagens to active mutagens. There are a large number of S. cerevisiae strains with varying abilities to produce cytochrome P-450. However, strain selection and ideal cultivation conditions are not well defined. We compared cytochrome P-450 levels in four different S. cerevisiae strains and evaluated the cultivation conditions necessary to obtain the highest levels. The amount of cytochrome P-450 produced by each strain varied, as did the incubation time needed to reach the maximum level. The highest cytochrome P-450 concentrations were found in media containing fermentable sugars. The NCYC 240 strain produced the...
