Optimization of thermostable proteases production under agro-wastes solid-state fermentation by a new thermophilic Mycothermus thermophilus isolated from a hydrothermal spring Hammam Debagh, Algeria
(
Elsevier Ltd
, 2022 , Article)
The present work investigates for the first time the presence and isolation of the thermophilic fungi from hydrothermal spring situated at the locality of Guelma, in the Northeast of Algeria. The production of the thermostable ...
Valorization and optimization of agro-industrial orange waste for the production of enzyme by halophilic Streptomyces sp.
(
Academic Press Inc.
, 2021 , Article)
This study underlines the biotechnical valorization of the accumulated and unusable remains of agro-industrial orange fruit peel waste to produce α-amylase under submerged conditions by Streptomyces sp. KP314280 (20r). The ...
Functionalization of silica-coated magnetic nanoparticles as powerful demulsifier to recover oil from oil-in-water emulsion
(
Elsevier Ltd
, 2021 , Article)
This study presents an innovative approach for the preparation of Fe3O4 nanoparticles covered with SiO2 shell (denoted as Fe–Si-MNP), which were used to recover oil recovery from oil-in-water emulsion (O/W-emul). The ...
Health risk assessment induced by trace toxic metals in tap drinking water: Condorcet principle development
(
Elsevier Ltd
, 2022 , Article)
Acute exposure to trace metals (TMs) in water is hazardous to human health. The average concentrations (Cavg.) and carcinogenic (CAR) and non-carcinogenic (non-CAR) risks of eight TMs to World Health Organization's (WHO) ...
Enhanced oil recovery using hyperbranched polyglycerol polymer-coated silica nanoparticles
(
Elsevier Ltd
, 2021 , Article)
Functionalized Fe3O4?SiO2 magnetic nanoparticles (Fe?Si-MNPs) coated with hyperbranched polyglycerol polymer were prepared and tested for oil recovery from oil in water (O/W) emulsions. The structure, chemistry, and surface ...
Solar photo-catalytic production of hydrogen by irradiation of cobalt co-doped TiO2
(
Elsevier Ltd
, 2021 , Article)
Cobalt (Co) co-doped TiO2 photocatalysts (P–Cs) with differing mass fractions of Co (% wt.) were synthesized, characterized, and evaluated toward the solar photocatalytic production of hydrogen (SP–CPOH) from a pure electron ...
Paper mill sludge as a source of sugars for use in the production of bioethanol and isoprene
(
MDPI AG
, 2020 , Article)
Paper mill sludge (PMS) solids are predominantly comprised of cellulosic fibers and fillers rejected during the pulping or paper making process. Most sludges are dewatered and discharged into landfills or land spread at a ...
Application of Fe3O4 magnetite nanoparticles grafted in silica (SiO2) for oil recovery from oil in water emulsions
(
Elsevier Ltd
, 2021 , Article)
In this study, an innovative magnetic demulsifier (MD) was prepared by grafting a silica layer onto the surface of the Fe3O4 magnetic nanoparticles (MNPs) using the modified Stober process. The MD was characterized using ...
Fabrication of titanium dioxide nanomaterial for implantable highly flexible composite bioelectrode for biosensing applications
(
Elsevier Ltd
, 2021 , Article)
Implantable and stretchable electrodes have managed to progress the medical field from a medical diagnosis aspect to a patient treatment level. They offer the ability to detect biosignals and conduct electrical current to ...
Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments
(
Elsevier Ltd
, 2020 , Article)
Large amounts of agricultural solid wastes (ASWs) and animal dung are produced annually causing serious environmental problem that requires proper treatment. The present study proposes a strategy for optimizing the anaerobic ...
