Diatoms are very diverse and highly productive organisms, found in a wide variety of environments. This study aims to analyze the growth lipid composition Phaeodactylum tricornutum, cultured an outdoor pilot-scale bubble column photobioreactor under natural conditions Chile for biodiesel production. Results showed that P. tricornutum cultures reached their highest biomass concentration (0.96 ± 0.04 kg m−3) after 14 days culturing, at stationary phase, with volumetric productivity 0.13 m−3...
Microalgae are eukaryotic or prokaryotic organisms, with high photosynthetic efficiency for biomass production. The constituent elements of microalgae can be extracted and used as raw material the production various products, such biodiesel, which main components fatty acid methyl esters (FAMEs). This study aimed to analyze lipids composition Phaeodactylum tricornutum cultured at outdoor photobiorreactor. P. samples showed 24.39% C16-C18 acids, 26.52% saturated acids (SFAs), 21.91%...
Herpes simplex viruses (HSVs) type 1 (HSV-1) and 2 (HSV-2) are highly prevalent in the human population, infections they produce lifelong with frequent reactivations throughout life. Both uncomfortable sometimes painful lesions orofacial genital areas, as well herpetic gingivostomatitis, among other clinical manifestations. At present, most common treatments against HSVs consist of nucleoside analogs that target viral polymerase. However, such drugs poorly effective for treating skin...

Brown algae biomass has been shown to be a highly important industrial source for the production of alginates and different nutraceutical products. The characterization this is necessary in order allocate its use specific applications according chemical biological characteristics variable resource. methods commonly used require long time analysis rigorous pretreatments samples. In work, nondestructive fast analyses morphological structures from Lessonia spicata Macrocystis pyrifera, which...
Plant alkaloids are natural secondary metabolites that have attracted great interest in the development of drugs for therapeutic applications due to their diverse bioactivities.
For biotechnological purposes, it is important to determine biochemical composition of microalgae biomass, for correctly addressing the valorization high-value compounds produced and enhancing economic feasibility cultivation process. This study aims analyze P. tricornutum cultivated at an outdoor pilot-scale bubble column photobioreactor under natural conditions in Chile, biofuel production order propose a tricronutum based biorefinery. The biomass concentration about 0.96 kg·m-3·d-1 with...
The use of biosilica, obtained from living diatoms, for energy applications has recently shown a great promise, mainly due to the high production cost such materials non-environmentally friendly processes. This study aims analyze frustule composition Phaeodactylum tricornutum dried biomass particularly concerning silicon percentage. To remove organic and inorganic impurities, frustules were purified by acid cleaning, with different results dependent on conditions applied. SEM/EDS analysis...

Eucalyptus globulus is an important forestry species for wood and pulp industry; however, its low cold resistance a serious disadvantage.In this work, chemometric techniques were applied on the leaves' free amino acid content of different E. genotypes in order to select tolerant genotypes.Pattern recognition methods based regularized discriminant analysis (RDA) used classify by using samples' foliar damages as reference resistance.Correlation between acids was determined from partial least...
Herpes simplex virus type 2 (HSV-2) is a human infectious agent with significant impact on public health due to its high prevalence in the population and ability elicit wide range of diseases, from mild severe. Although several antiviral drugs, such as acyclovir, are currently available treat HSV-2-related clinical manifestations, their effectiveness poor. Therefore, identification development new drugs against HSV-2 necessary. Seaweeds attractive candidates for purposes because they vast...
Several studies have been done in order to detect antibiotics from natural sources, seaweeds among them.With the aim of identifying antibacterial compounds, 6 species evaluated.The raw extracts were analyzed against bacteria, Gram-positive and negative, with diffusi on discs bioautography, then, they characterized by GC-MS.The Gracilaria chilensis, Ulva Complex Macrocystis pyrifera present inhibition bacterial growth tested strains.Three molecules, Phytol, 6-methyl-2-phenylquinoline...
The feeding behavior in fish is a complex activity that relies on the ability of brain to integrate multiple signals produce appropriate responses terms food intake, energy expenditure, and metabolic activity. Upon stress cues including viral infection or mediators such as proinflammatory cytokines, prostaglandins, cortisol, both Pomc Npy/Agrp neurons from hypothalamus are stimulated, thus triggering response controls storage expenditure. However, how appetite modulators neuro-immune link...
