Journal of Biotechnology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 1, 2025

Waste cooking oils (WCOs) are common wastes and promising green, eco-friendly sustainable feedstocks for bio-based applications. While the primary valorisation strategy revolves around concept of waste-to energy, new research trends have emerged in last decade. This systematic review provides a comprehensive analysis current state art conversion WCOs into molecules. Based on PRISMA methodology, 64 papers were selected using different databases sources, such as: PubMed, ScienceDirect, Scopus MDPI. The data extraction process focused studies reporting biological chemical value-added bioproducts. Many publications deal with development bioactive molecules, including biosurfactants, application pharmaceuticals, food, cosmetics, bioremediation. Bioconversion processes mainly featured engineered Yarrowia lipolytica Escherichia coli strains, even if additional microorganisms also employed. In same way, been thoroughly studied. A smaller segment is directed to production feed supplements soaps. Regulatory constraints limit further due potential contaminants, while soap needs stability studies. present shows outcomes through molecules products. Despite wide range applications, these findings identify that scalability economic sustainability require investigation. study seeks summarize gaps advance industrialization valorisation.

Large-scale underground hydrogen storage (UHS) plays a vital role in energy transition. H2-brine interfacial tension (IFT) is crucial parameter structural trapping geological locations and gas–water two-phase flow subsurface porous media. On the other hand, cushion gas, such as CO2, often co-injected with H2 to retain reservoir pressure. Therefore, it imperative accurately predict (H2 + CO2)-water/brine IFT under UHS conditions. While there have been number of experimental measurements on H2-water/brine IFT, an accurate efficient model conditions still lacking. In this work, we use molecular dynamics (MD) simulations generate extensive databank (840 data points) over wide range temperature (from 298 373 K), pressure 50 400 bar), gas composition, brine salinity (up 3.15 mol/kg) for typical conditions, which used develop machine learning (ML)-based equation. Our ML-based equation validated by comparing available equations various systems (H2-brine/water, CO2-brine/water, CO2)-brine/water), rendering generally good performance (with R2 = 0.902 against 601 points). The developed can be readily applied implemented applications.

Abstract Pisauridae Simon, 1890 or “nursery web spiders” are a global and heterogenous assemblage of spider genera with diverse lifestyles, containing builders webless species, as well terrestrial semi-aquatic notably “fishing spiders”, genus Dolomedes Latreille, 1804. Incomplete, unresolved, conflicting phylogenies have so far hampered testing for pisaurid monophyly evolution. Here, we broadly address these questions within phylogenomic comparative framework. Our goals i) reconstruction robust phylogeny to test the amend classification; ii) estimation evolutionary shifts trends in lifestyles capture webs; iii) evaluation hypotheses morphological trait association lifestyle. To this end generate subgenomic data (ultraconserved elements UCE) 53 species 28 genera. We analyze using maximum likelihood, Bayesian, multi-species coalescence approaches, two different phylogenetic time calibration methods, RelTime MCMCtree. Consistent across analytical our reject both . “Pisaurid” fall into three clades: 1) Focal Clade I groups majority, including Pisaura 1886, hence representing true pisaurids; 2) II = Blandinia Tonini et al., 2016 is sister Trechaleidae Lycosidae Sundevall, 1833; 3) III fishing raft spiders , Megadolomedes Davies Raven, 1980, Ornodolomedes Raven Hebron, 2018 II, Trechaleidae, Lycosidae. taxonomy, based on complementary taxa evidence, resurrects Dolomedidae 1876 include Oceanic Bradystichus 1884, Caledomedes 2018, Mangromedes Tasmomedes 2018. Both MCMCtree analyses yield comparable divergence estimations: origin estimated between 29 40 Ma; 21 34 10 17 9 16 Ma. In order avoid misleading significant correlations and/or over-resolved ancestral states, performed taxon sampling bias correction all analyses.

Crystal violet (CV) is a disinfectant and antifungal agent used in aquaculture that plays vital role treating aquatic diseases sterilizing water. However, its potential for strong toxicity, including carcinogenicity mutagenicity, upon accumulation the body raises concerns regarding safe use. Therefore, there growing need quantitative detection of CV early application stages to ensure human safety. Recently, Raman spectroscopy-based surface-enhanced scattering (SERS) research has been actively conducted; consequently, an alveolar-mimicking SERS paper (AMSP) inspired by structure lungs was developed. The AMSP optimized through various factors, type, reducing agent, concentration, reaction time. This optimization enhanced surface area interaction with target substances promoted hotspot formation, resulting performance. substrate exhibited exceptional uniformity, reproducibility, reliability. successfully detected at concentration 1 nM laboratory settings.
