Carbocation rearrangement, methyl migration, and long-range hydrogen transfer in phenyl fatty acid esters

open access: yesJournal of Chemical Research, 2023
Various isomers can be observed in the Friedel–Crafts alkylation of benzene. However, the mechanism and influence of these isomerization reactions were still unclear. In this work, several methyl phenylundecanoate were analyzed by gas chromatography–mass

Use of Microorganisms in the Recovery of Oil From Recalcitrant Oil Reservoirs: Current State of Knowledge, Technological Advances and Future Perspectives

open access: yesFrontiers in Microbiology, 2020
The depletion of oil resources, increasing global energy demand, the current low, yet unpredictable, price of oil, and increasing maturity of major oil fields has driven the need for the development of oil recovery technologies that are less costly and ...

Application of thermotolerant petroleum microbes at reservoir conditions for enhanced oil recovery

open access: yesPetroleum, 2023
Primary oil recovery is the first stage of hydrocarbon production in which a reservoir uses its natural energy to force hydrocarbon to its wellbore. Secondary oil recovery comes to play when hydrocarbons can no longer be further produced by natural means.

Comparison of microbial community structures between oil and water phases in a low-permeability reservoir after water flooding

open access: yesEnergy Reports, 2023
The application of Microbial Enhanced Oil Recovery relies heavily on the microorganisms in oil wells. However, due to the difficulties in separating bacteria from oil samples, studies on bacterial communities in oil samples are limited.

Microbial Enhanced Oil Recovery [PDF]

open access: yes, 2012
Nowadays the majority of the world's energy comes from crude oil. A large proportion of this valuable and non-renewable resource is left behind in the ground after the application of conventional oil extraction methods. Moreover, there is a dire need to produce more crude oil to meet the worldwide rising energy demand which illustrates the necessity of

Microbial Enhanced Oil Recovery

open access: yes, 2016
The ever-rising global demand for energy and the issue of large volumes of unrecovered oil after primary and secondary oil production operations are driving the development and/or advancement of enhanced oil recovery (EOR) techniques. Conventional EOR processes include thermal, immiscible and miscible gas injection, chemical, and microbial enhanced oil

A Microcapsule-Integrated smRandom-seq Platform Enables Fixation-Free Single Microbe RNA Sequencing. [PDF]

open access: yesAdv Sci (Weinh)
We developed a microcapsule‐integrated high‐throughput fixation‐free single‐microbe RNA‐seq workflow in which microbes are encapsulated in aqueous two‐phase microcapsules for physical confinement of nucleic acids. This platform enables co‐encapsulation with barcoded beads for sequencing and reveals that fixation‐free processing enhances transcriptomic ...
