Genetic engineering of the precursor supply pathway for the overproduction of the nC14-surfactin isoform with promising MEOR applications

Microbial Cell Factories, 2021
Background Surfactin, a representative biosurfactant of lipopeptide mainly produced by Bacillus subtilis, consists of a cyclic heptapeptide linked to a β-hydroxy fatty acid chain.

Microbial enhanced oil recovery through deep profile control using a conditional bacterial cellulose-producing strain derived from Enterobacter sp. FY-07

Microbial Cell Factories, 2020
Background Heterogeneity of oil-bearing formations is one of major contributors to low oil recovery efficiency globally. Long-term water flooding will aggravate this heterogeneity by resulting in many large channels during the exploitation process. Thus,

Microorganisms’ effect on the wettability of carbonate oil-wet surfaces: implications for MEOR, smart water injection and reservoir souring mitigation strategies

Journal of Petroleum Exploration and Production Technology, 2019
In upstream oil industry, microorganisms arise some opportunities and challenges. They can increase oil recovery through microbial enhanced oil recovery (MEOR) mechanisms, or they can increase production costs and risks through reservoir souring process ...

Potential Degradation of SARA (Saturated, Aromatics, Resinics, Asphaltenes) Fractions of Crude Oil by Reservoir Indigenous Bacteria from South Sumatera

Microbiology Indonesia, 2018
MEOR (Microbial Enhanced Oil Recovery) technology utilizes metabolic activity of microorganisms such as degradation of hydrocarbon fractions which alters oil characteristics to facilitate and increase oil recovery from reservoir. This research focused on

Microbially Enhanced Oil Recovery (MEOR) can Benefit from Bioremediation

Journal of Bioremediation and Biodegradation, 2012
Bioremediation of hydrocarbon contaminated sites has a long history and great achievements were made during the last decades. However, this had too little impact on microbially enhanced oil recovery (MEOR). Now that world-wide demand for oil exceeds the supply it has become necessary to use the scientific achievements from the field of bioremediation ...

Microbial enhanced oil recovery

, 2018
Oil is a crucial source of energy and one of the main factors driving the world’s economy. Currently, oil production technologies recover only about 40% of the oil originally present in the reservoirs.

Effect of inorganic nutrients on bacterial community composition in oil-bearing sandstones from the subsurface strata of an onshore oil reservoir and its potential use in Microbial Enhanced Oil Recovery.

PLoS ONE, 2018
Microbial Enhanced Oil Recovery (MEOR) is a promising strategy to improve recovery of residual oil in reservoirs, which can be performed by promoting specific indigenous microorganisms.

Microbial enhanced oil recovery: interfacial tension and biosurfactant-bacteria growth

Journal of Petroleum Exploration and Production Technology, 2019
Microbial enhanced oil recovery (MEOR) is a method that utilises bacteria or bioproducts to increase oil recovery at the tertiary stage. Clostridium sp. produces biosurfactant that alters rock–fluid properties and increases oil detachment.
