Investigation and mechanism of headspace corrosion in metal cans filled chicken noodle soup
This study investigated how volatile compounds in the headspace of canned and retorted chicken soup caused corrosion in the metallic package. Chicken soups packaged in glass jars and plastic pouches were used as controls. The results showed that sulphur-containing compounds were mainly associated with the initiation of corrosion in the tested samples. These compounds attacked the protective polymeric coating in the cans and created avenues for electrolytes in the soup to react with and cause corrosion in the metal. AbstractThis study demonstrated a method to investigate corrosion formation in the headspace of canned chicke...

Impact of light spectra on photo-fermentative biohydrogen production by Rhodobacter sphaeroides KKU-PS1
Bioresour Technol. 2023 Dec 16:130222. doi: 10.1016/j.biortech.2023.130222. Online ahead of print.ABSTRACTPurple non-sulphur bacteria can only capture up to 10 % light spectra and only 1-5 % of light is converted efficiently for biohydrogen production. To enhance light capture and conversion efficiencies, it is necessary to understand the impact of various light spectra on light harvesting pigments. During photo-fermentation, Rhodobacter sphaeroides KKU-PS1 cultivated at 30 ⁰C and 150 rpm under different light spectra has been investigated. Results revealed that red light is more beneficial for biomass accumulation, wher...

Tracing sulfate sources and transformations of surface water using multiple isotopes in a mining-rural-urban agglomeration area
In this study, the SO42- in the surface water of Huaibei mining area were monitored and the main sources of pollution and biogeochemical processes were identified using stable isotopes (δD, δ18O-H2O, δ34S-SO42- and δ18O-SO42-) and water chemistry. The results demonstrated the SO42- content in the Huihe River and Linhuan subsidence water area (SWA) is higher than that in other rivers and SWAs, which exceeded the environmental quality standard of surface water. The SO42- content of different rivers and SWAs showed seasonal differences, and the dry season was higher than the wet season. In addition, the SO42- in Tuohe Riv...

Non-negligible contribution of high-level volatile sulphur compounds to ozone photochemical formation in an industry zone in the North China Plain
This study presents direct evidence that high concentrations of volatile sulphur compounds (VSCs) accelerate the photochemical production of O3. We analysed three high O3 cases (Cases I, II, and III) in which the O3 concentrations were high but the compositions of O3 precursors differed. An analysis of the O3 precursors and the magnitudes of the associated ROx (ROx = ·OH + ·HO2 + ·RO2) reactivities amongst three cases revealed that VSCs may play an important role in O3 production. Case I showed high loadings of VSCs, mainly dimethyl sulphide (DMS), and the simulated diurnal average concentration of radicals...

A compositional data model to predict the isotope distribution for average peptides using a compositional spline model
AbstractWe propose an updated approach for approximating the isotope distribution of average peptides given their monoisotopic mass. Our methodology involves in-silico cleavage of the entire UNIPROT database of human-reviewed proteins using Trypsin, generating a theoretical peptide dataset. The isotope distribution is computed using BRAIN. We apply a compositional data modelling strategy that utilizes an additive log-ratio transformation for the isotope probabilities followed by a penalized spline regression. Furthermore, due to the impact of the number of sulphur atoms on the course of the isotope distribution, we develop...
