Petroleum hydrocarbons, heavy metals and agricultural pesticides have mutagenic, carcinogenic, immunotoxic teratogenic effects cause drastic changes in soil physicochemical microbiological characteristics, thereby representing a serious danger to health environment. Therefore, pollution urgently requires the application of series biological techniques treatments minimize extent damage. Among them, bioremediation has been shown be an alternative that can offer economically viable way restore...
The unbridled use of fossil fuels is a serious problem that has become increasingly evident over the years. As such contribute considerably to environmental pollution, there need find new, sustainable sources energy with low emissions greenhouse gases. Climate change poses substantial challenge for scientific community. Thus, renewable through technologies offer maximum efficiency minimal pollution and carbon major goal. Technology related hydrogen as fuel one most promising solutions future...
Two new highly-efficient and eco-friendly biosorbents comprised of magnetite, chitosan Chlorella vulgaris (MCC) or Arthrospira platensis (MCA) were prepared in such a way to be easily separated reused for removing different classes antibiotics as tetracycline (TC), ciprofloxacin (CIP) amoxicillin (AMX) from wastewater. They characterized using SEM, FTIR TGA. Biosorption experiments performed investigate the impact pH, biosorbent dosage, initial antibiotic concentration, contact time,...
This study aimed to optimize the spray drying process for microencapsulation of Lactobacillus acidophilus La-5, using inulin as coating agent increase its gastrointestinal survival. Moreover, survival microencapsulated and free microorganism incorporated or not in a synbiotic mousse vitro simulated conditions was evaluated. Microencapsulation were optimized at 80 mL/min, 82%, 10%, feed flow, aspiration rate, concentration, respectively. Subsequently, diet produced with addition both...
In this review, the main properties of olive mill solid waste, primary by-product oil production, and its feasibility as a feedstock for anaerobic digesters operating at laboratory-, pilot- industrial-scales are discussed in detail. Nutrient addition thermal pretreatments were found to have potential address challenges arising from high carbon-to-nitrogen ratio, low pH, concentration phenolic compounds. Furthermore, co-digestion with different organic feedstocks has been identified one most...
To reduce CO 2 emissions and simultaneously produce biomass rich in essential fatty acids, Chlorella vulgaris CCAP 211 was continuously grown a tubular photobioreactor using air alone or enriched with as the sole carbon source. While on one hand, nitrogen‐limited conditions strongly affected growth, conversely, they almost doubled its lipid fraction. Under these 0, 2, 4, 8, 16% (v/v) , maximum concentration 1.4, 5.8, 6.6, 6.8, 6.4 g DB L −1 dry basis, consumption rate 62, 380, 391, 433, 430...
This study aimed to extract bioactive compounds from tomato waste through ultrasound-assisted extraction (UAE), using ethanol as solvent. Process optimization was carried out by a central composite design of 33 runs for response surface modelling, simultaneously analyzing the effect temperature (T), time (t), volume (V), liquid-to-solid ratio (L/S), amplitude (A), pulser duration (on), and their interaction. The best conditions found desirability method (T = 65 °C, t 20 min, L/S 72 mL/g, A...
Summary This study focused on the use of a non‐conventional extraction technology by employing high‐pressure high‐temperature stirred reactor to extract polyphenols from grape skins. Extraction time (15–330 min) and temperature (30–150 °C) were selected as independent variables, their effects studied. A preliminary kinetic revealed that second‐order model fitted satisfactorily experimental results ( R 2 ≥ 0.9798). Total polyphenol yield total flavonoid (TF) yield, well antiradical power...
Summary The valorisation and management of agri‐food waste are currently hot investigation topics which probe the recovery valuable compounds, such as polyphenols. In this study, high‐pressure/high‐temperature extraction ( HPTE ) ultrasound‐assisted UAE have been used to study phenolic compounds from grape marc olive pomace in hydroalcoholic solutions. main both extracts were identified by HPLC ‐ DAD . Besides yield (total polyphenol flavonoid content) antiradical power, degradation under...
Cupuassu is a fruitful species from the Amazon basin with great economical potential, due to multiple uses of its pulp and seeds in food cosmetic industries. This fruit generates large amounts solid waste, which, despite high content bioactive compounds, discarded environment. Therefore, aim reusing these wastes adding economic value, we investigated nutritional potential seed by-product resulting industrial cupuassu oil extraction. The was submitted green extraction, contents compounds were...
In this work pyrolysis of palm oil and lignin has been investigated using a two-stage process at 550 °C, with first step configuration continuous condensation for vapors separation gases, second distillation vapors. Experiments were realized as oil, palmitic acid, Kraft lignin, well co-pyrolysis oil/lignin, acid/lignin acid/guaiacol. It shown that the addition improves quality bio-oil, thanks to conversion fatty acids coproduct acid methyl esters (FAME). The production in reaction...
The potential of technical lignins as secondary raw materials is discussed. characteristics lignin pyrolysis, with particular emphasis on slow pyrolysis technologies, are briefly summarized. process, which can be self-sustained by burning the coproduced gas, primarily produce high-quality biochar in significant amounts, to used a fuel, reductant metallurgy, and an adsorbent catalyst component. Together, amounts bio-oil produced, rich guaiacols, commercial expensive chemicals produced today...
