Apr 17, 2018 He found that both yields of essential oil and antioxidant activity of SFC extract were higher than those from other two methods . S-CO 2 modified with 2% ethanol at 300 bar and 40 C gave higher extracting selectivity of vinblastine ( 53 , Fig. 7 ) (an antineoplastic drug) from Catharanthus roseus , which is 92% more efficient for vinblastine ...

Ag-TiO2/biofilm/nitrate interface enhanced visible light ...

Due to the pivotal role of Ag-TiO 2 /biofilm/nitrate interface, enhanced visible light-assisted biodegradation of tetracycline (TC) in anoxic system was realized through both batch experiment and long-term operation in this study. The results of the batch experiment elucidated that 50 mg L −1 TC could be completely removed within 10 h in Ag-TiO 2 /biofilm/nitrate system.

In this paper, we have also compared the performance of this reactor to other reactors such as the batch, micro, thin-film, and the vortex reactor, among others, and have found the photo-Rotor-Stator Spinning Disk Reactor to have superior productivity as well as higher productivity per vol. (2.8 mol s-1 m-3).

Jan 21, 2022 B15 samples were found to correspond closely to B0 samples, with a similar no. of species detected. B100 samples showed a significant increase in no. of species generated at 24-72 h relative to B0 and B15; however, a similar no. of species were obsd. at 168 h for all samples, indicating a similar level of base oil oxidn. at the final oxidn. point.

Bacterial Metabolism - Medical Microbiology - NCBI Bookshelf

Metabolism refers to all the biochemical reactions that occur in a cell or organism. The study of bacterial metabolism focuses on the chemical diversity of substrate oxidations and dissimilation reactions (reactions by which substrate molecules are broken down), which normally function in bacteria to generate energy. Also within the scope of bacterial metabolism is the study of the …

Oct 15, 2016 The aim of this reactor is to produce a bio‐oil that will not contain any particle. It uses a reactor that is cyclone in nature integrated with hot gas filter. Both the biomass feedstock and the inert heat are fed into the cyclone as particles while the vapours that are recycled are made to transport the solids during the process.

The highest space-time yield (STY) found for this system was 3.72 mmolmL –1 h –1 with a yield of 28% using the XeBr lamp, which translates to roughly 0.96 gh –1. High conversions were reached for the 282 and 308 nm lamps at lower concentrations and flow rates, but those productivities were considerably lower.
