Carbon dioxide can inhibit biofilms formation and cellular properties of Shewanella putrefaciens at both 30 °C and 4 °C

Carbon dioxide was widely used to control microorganisms in aquatic products packaging. Both 30 b0C and 4 b0C gas were tested, as well as the control mechanism of CO2082 on biofilm production and cell integrity of S. putrefaciens, the dynamic production process of biofilms, cellular surface properties, and cellular metabolic characteristics of S. putrefaciens at both 30 °C and 4 b0C in pure COu2082 gas. As shown by the crystal violet staining process, confocal laser scanning microscopy analysis, and field emission scanning electron microscopy analysis, the dynamic formation of S. putaciens biofilms was obviously postponed by CO2082 due to integral cellular morphology. The number and viability of sessile cells in S. putfaciens biofilms was considerably less than those in normal air composition, according to S. puttile cells' numbers and viability. By CO2082, it could be concluded that the dynamic formation process of S. putfaciens biofilms and cellular metabolic properties could be slowed.

Effects of ethanol modified supercritical carbon dioxide extraction and particle size on the physical, chemical, and functional properties of yellow pea flour

However, the effect of this extraction, in combination with different flour particle sizes, was not established, and is therefore the subject of this research. FINDINGS: The interaction between SC02082 + EtOH extraction and yellow pea flour particle size results in differences in physical, chemical, and functional characteristics. SIGNIFICANCE AND NOVELTY: The SC-2082 + EtOH extraction process, along with particle size, can be a cost-effective way to enhance yellow pea flour's functionality and ultimately expanding its use in food manufacturing.

Food potential of Scenedesmus obliquus biomasses obtained from photosynthetic cultivations associated with carbon dioxide mitigation

This research was therefore designed to investigate the nutritional value of Scenedesmus obliquus biomasses obtained from photosynthetic cultures rich with 3, 5, 10, 20, and 25% carbon dioxide. The presence of most essential amino acids at recommended levels for the human diet led to increased amino acids and proteins synthesis in Cultivations with 3, 5, and 10% COu2082; the protein content reached values above 56% of the dry biomass and high protein quality. Higher CO2182 enrichment was intensified in Lipid synthesis, with 15. 8% with 20% COu2082, 15. 0% with 20% COu2082, and 17. 9% with 25 percent COu2082. Our results showed that CO2u2082 treatments significantly reduced all compound concentrations in S. obliquus biomasses, which gave a satisfactory composition for use as food and as ingredients.

Spraying Water Microdroplets Containing 1,2,3-Triazole Converts Carbon Dioxide into Formic Acid.

For the reduction of atmospheric carbon dioxide reduction at room temperature by 1,2,3-triazole-containing water microdroplets, we describe. The capture of CO2 to produce the bicarbonate anion and conversion to form the formate anion is monitored by a mass spectrometer operating in negative ion mode. The reaction is thought to have occurred at the GLI, where Tz donates the proton and the hydroxide, resulting in a stepwise yield of electrons to reduce gas-phase CO2 to FA.

Near-UV and Visible Light Degradation of Iron (III)-Containing Citrate Buffer: Formation of Carbon Dioxide Radical Anion via Fragmentation of a Sterically Hindered Alkoxyl Radical.

Since near-UV and visible light exposure, Fe 3+ -citrate complexes can act as potent photosensitizers, and recent reports have found evidence for the photo-production of a potent reductant, carbon dioxide radical anion (Fe 3+ -citrate complexes). The mechanisms of u2022 CO 2 - development are currently unknown, but plans against u2022 CO 2 - formation in pharmaceutical formulations that rely on the use of citrate buffer are also unknown. Experiments with stable isotope-labeled citrate indicate that the central carboxylate group of citrate is the key source of u2022 CO 2 emissions.

The effect of transport services and ICTs on carbon dioxide emissions in South Africa.

As global warming and climate change, the increasing trend in carbon dioxide emissions has a direct effect on economic life. South Africa has emerged as one of the world's top ICT and transportation infrastructure in the sub-Saharan African region, with South Africa ranked as one of the world's top nations in ICT and transport infrastructure. Opposing claims about how ICT and tranport services influence carbon dioxide pollution exist. The report explores the role that ICTs and the transportation industry play in South Africa's carbon dioxide emissions. Implications of the findings include the urgent need to have electricity that drives ICT devices and equipment that comes from renewable and sustainable sources rather than from heavy polluting sources.
