microalgae in the red phase can produce significant amounts of astaxanthin, lutein, and fatty acids (FAs), which are valuable antioxidants nutraceutics cosmetics. Extraction FAs from disrupted biomass
Astaxanthin and lutein, antioxidants used in nutraceutics cosmetics, can be extracted from several microalgal species. In this work, investigations on astaxanthin lutein extraction Haematococcus pluvialis (H. pluvialis) the red phase were carried out by means of supercritical fluid (SFE) technique, which CO₂ was as extracting solvent with ethanol co-solvent. The experimental activity performed using a bench-scale reactor semi-batch configuration varying times (20, 40, 60, 80 min),...
Lutein has several benefits for human health, playing an important role in the prevention of age-related macular degeneration (AMD), cataracts, amelioration first stages atherosclerosis, and some types cancer. In this work, Scenedesmus almeriensis microalga was used as a natural source supercritical fluid (SF) extraction lutein. For purpose, optimization main parameters affecting extraction, such biomass pre-treatment, temperature, pressure, carbon dioxide (CO₂) flow rate, performed. stage,...
In this article, microalgae
This research shows that carbon dioxide supercritical fluid (CO2-SF) is an emerging technology for the extraction of high interest compounds applications in manufacturing pharmaceuticals, nutraceuticals, and cosmetics from microalgae. The purpose this study to recover fatty acids (FAs) and, more precisely, eicosapentaenoic acid (EPA) Nannochloropsis gaditana biomass by CO2-SF extraction. In paper, effect mechanical pre-treatment was evaluated with aim increasing FAs recovery. Extraction...
Microalgae Dunaliella salina contains useful molecules such as β-carotene and fatty acids (FAs), which are considered high value-added compounds. To extract these molecules, supercritical carbon dioxide was used at different operative conditions. The effects of mechanical pre-treatment (grinding speed 0–600 rpm; time 2.5–7.5 min) operating parameters for extraction, biomass loading (2.45 7.53 g), pressure (100–550 bars), temperature (50–75 °C) CO2 flow rate (7.24 14.48 g/min) by varying the...
Abstract. Passive air samplers (PASs), which provide time-averaged concentrations of gaseous mercury over the timescale weeks to months, are promising for filling a gap in monitoring atmospheric worldwide. Their usefulness will depend on their ease use and robustness under field conditions, availability affordability, most notably, ability results acceptable precision accuracy. Here we describe comparative evaluation three PASs with respect precisely accurately record background at sites...
Abstract In this work, the performance of carotenoids extraction from Rhodotorula spp red yeast (strain ELP2022) using supercritical CO 2 (CO -SFE) was compared to traditional technique with organic solvent. For purpose, cultured in liquid medium, pre-treated glass beads 0.1 M NaHCO 3 , and lyophilized. The by -SFE carried out a bench scale equipment at 300, 400, 500 bar whilst maintaining constant flow rate (6 mL/min) temperature (40 °C) resulting an average yields 60.8 ± 1.1, 68.0 1.4,...
Abstract Torularhodin is a dark pink colored carotenoid belonging to the xanthophylls group that can be biologically synthesized by red yeasts, especially Rhodotorula and Sporobolomyces genera. The growing interest in this molecule due its biological activities such as antioxidant, anticholesterolemic, anti-inflammatory, antimicrobial, anticancer. To satisfy potential commercial markets, numerous methods have been proposed develop cost-effective environmentally friendly downstream process...
The disposal of waste tires represents a relevant problem within the management strategy European community: more than 300 000 are estimated to reach their end life each year in 27 member states Union and comparable amounts found North America, Latin Asia, Middle East. global total is ∼1 rising year. (Source: Tyre Recycling Association (ETRA), 2006.) It well-known that scrap possess high volatiles low ash contents, together with heating value higher coal biomass. These properties make them...
The opportunity of using refuse-derived fuel (RDF) to produce gas seems be promising, and particular attention has been focused on alternative process technologies such as pyrolysis gasification. Within this frame, present work relates experimental tests obtained results a series surveys RDF gasification with steam, performed by means bench-scale rotary kiln plant at different temperatures, thermogravimetry (TG) infrared spectrometry (Fourier transform infrared, FTIR) characterize the...
Mercury (Hg) fate and transport research requires more effort to obtain a deep knowledge of its biogeochemical cycle, particularly in the Southern Hemisphere Tropics that are still missing distributed monitoring sites.Continuous atmospheric Hg concentrations trend worldwide is relevant for effectiveness evaluation Minamata Convention on (MCM) actions. In this context, Gaseous Elemental (GEM) total mercury (THg) precipitations were monitored from 2013 2019 at Amsterdam Island Observatory (AMS...
Abstract In the framework of Italian Special Network for Mercury (ISNM) “Reti Speciali”, a sampling campaign to monitor atmospheric mercury (Hg) was carried out at Monte Sant’Angelo (MSA). This is coastal monitoring station in Apulia region, representative Southern Adriatic area, within Mediterranean basin. work presents continuous Gaseous Elemental (GEM) measurements over about three years MSA, using Lumex RA-915AM analyzer. The aim obtain dataset suitable analysis Hg concentrations terms...
The aim of the paper is to evaluate bioenergy and bio-based material recovery from fruit scraps through an innovative process, e.g., supercritical water gasification, which presents several advantages in comparison traditional processes for energy matter recovery. In particular, experimental tests peach were carried out using bench-scale plant plug flow reactor type, selected liquid can be pumped until 300 bar heated 600 °C achieve condition water. main results showed that, range feed rate...
To support the effectiveness of Minamata Convention, accurate determinations mercury (Hg) in natural waters is an important but certainly challenging task due to low concentrations expected ambient samples. Mercury contamination may occur from many sources such as unproperly-cleaning storage bottles or use reagents for sample analysis with Hg traces, thus leading analyst easily run into errors. In our work, we propose some key modifications United States Environmental Protection Agency(EPA)...
The Global Mercury Observation System (GMOS) network, initially a five-year project (2010-2015) funded by the European Commission, continued as GEO Flagship program to support for (GOS4M). GMOS was envisioned coordinated global observing system monitor atmospheric mercury (Hg) on scale, and evaluate effective implementation of Minamata Convention (MCM).
