Growth is one of the main biological processes in aquatic organisms that is affected by environmental fluctuations such as upwelling (characterized by food-rich waters). In fish, growth is directly related with skeletal muscle increase; which represents the largest tissue of body mass. However, the effects of upwelling on growth, at the physiological and molecular level, are unknown. This study used Girella laevifrons (one of the most abundant intertidal fish in Eastern South Pacific) as a biological ...

This work reports the first successful application of graphene oxide (GO) and partially reduced GO (rGO) as redox mediator (RM) to increase the biotransformation of the recalcitrant iodinated contrast medium, iopromide (IOP). Results showed that GO-based materials promoted up to 5.5 and 2.8-fold faster biotransformation of IOP by anaerobic sludge under methanogenic and sulfate-reducing conditions, respectively. Correlation between the extent of reduction of GO and its redox-mediating capacity was demonstrated, ...

The survival was determined in different conservation conditions of: somatic coliphages, F-specific RNA bacteriophages and phages infecting Bacteroides fragilis proposed as model micro-organisms for water quality control. Titres of phages of all groups either in pure culture phage suspensions or in naturally occurring phage suspensions were stable at (−70±10) °C and at (−20±5) °C when protected with glycerol. Moreover, phage analysis of stored suspensions demonstrated that their numbers were homogeneous, ...

Tomato waste is an excellent source of nutrients, micronutrients, and bioactive compounds. Some extraction technologies have been used to recover these pigments for their proven biological activities. In this study, solid-state fermentation with Aspergillus niger GH1 was used as a bioprocess for carotenoid extraction and recovery in tomato waste. The chemical composition was evaluated, in addition to the viability of the tomato waste as a solid-fermentation substrate. The results showed that at ...

Laser Speckle Contrast Imaging (LSCI) is an optical technique used to generate blood flow maps with high spatial and temporal resolution. It is well known that in LSCI, the speckle size must exceed the Nyquist criterion to maximize the speckle's pattern contrast. In this work, we study experimentally the effect of speckle-pixel size ratio not only in dynamic speckle contrast, but also on the calculation of the relative flow speed for temporal and spatial analysis. Our data suggest that the temporal ...

The mechanical properties of hard and soft wheat cultivars at different structural-levels were evaluated at 10% and 15% moisture content by AFM, IIT and compression test. Nano and micro-indentation tests revealed that outer-pericarp cells of soft cultivar were stiffer than hard cultivar at 10% moisture. Bran-layers stiffness was reduced as a consequence of higher moisture levels in both cultivars. Additionally, endosperm hardness and stiffness were similar in both cultivars at 10% moisture, although ...

The redox-mediating capacity of magnetic reduced graphene oxide nanosacks (MNS) to promote the reductive biodegradation of the halogenated pollutant, iopromide (IOP), was tested. Experiments were performed using glucose as electron donor in an upflow anaerobic sludge blanket (UASB) reactor under methanogenic conditions. Higher removal efficiency of IOP in the UASB reactor supplied with MNS as redox mediator was observed as compared with the control reactor lacking MNS. Results showed 82% of IOP removal ...

Metal-humic acid complexes were synthesized and immobilized by a granulation process in anaerobic sludge for their application as solid-phase redox mediators (RM) in the biotransformation of iopromide. Characterization of Ca- and Fe-humic acid complexes revealed electron accepting capacities of 0.472 and 0.556milli-equivalentsg(-1), respectively. Once immobilized, metal-humic acid complexes significantly increased the biotransformation of iopromide in upflow anaerobic sludge blanket (UASB) reactors. ...

The adsorption and desorption of boric acid onto reactive materials such as metal (hydr)oxides and natural organic matter are generally considered to be controlling processes for the leaching and bioavailability of boron (B). We studied the interaction of B with ferrihydrite (Fh), a nanosized iron (hydr)oxide omnipresent in soil systems, using batch adsorption experiments at different pH values and in the presence of phosphate as a competing anion. Surface speciation of B was described with a recently ...

Microbial communities inhabiting extreme environments such as Salar de Huasco (SH) in northern Chile are adapted to thrive while exposed to several abiotic pressures and the presence of toxic elements such as arsenic (As). Hence, we aimed to uncover the role of As in shaping bacterial composition, structure, and functional potential in five different sites in this altiplanic wetland using a shotgun metagenomic approach. The sites exhibit wide gradients of As (9 to 321 mg/kg), and our results showed ...

Polyextremophilic bacteria can thrive in environments with multiple stressors such as the Salar de Huasco (SH) environment. Microbial communities in SH are exposed to high atmospheric pressure, high UV radiation, wide temperature ranges, salinity gradient and the presence of toxic compounds such as arsenic (As). In this work we focus on arsenic stress as one of the main adverse factors in SH and bacteria that belong to the Exiguobacterium genus due to their plasticity and ubiquity. Therefore, our ...

In this work, the adsorption of a pharmaceutical pollutant, Naproxen (NPX), on activated carbon electrodes was improved through electroadsorption treatment under anodic polarization. After that, the contaminant was electrochemically degraded favoring the reactivation of the adsorbent material. The electroadsorption tests were performed with selected anodic potentials up to 1.1 V vs. NHE. The NPX removal increased from 14.2 mg/g (32.3%), during adsorption without electric potential, to 18.3 mg/g (42. ...
