摘要:
The present disclosure relates to isolation, identification and application of Shewanella putrefaciens strain LH4:18 that grows, under denitrifying anaerobic conditions, on crude oil as the sole carbon source. This organism assists in oil release from substrate in reservoir simulations when grown on either lactate or peptone as a carbon source. Shewanella putrefaciens strain LH4:18 can be used alone or in concert with other microorganisms to improve oil recovery.

摘要:
Methods, microorganisms, and compositions are provided wherein oil reservoirs are inoculated with microorganisms belonging to Pseudomonas stutzeri and medium including an electron acceptor. The Pseudomonas stutzeri grow in the oil reservoir to form plugging biofilms that reduce permeability in areas of subterranean formations thereby increasing sweep efficiency, and thereby enhancing oil recovery.
摘要:
A process was developed for expressing antimicrobial peptides in a recombinant host cell that eliminates host cell toxicity and antimicrobial peptide degradation, as well as providing a process for rapid purification. Fusion proteins comprising a periplasmic targeting signal, cleavage site, and antimicrobial peptides provide the basis for this process which produces antimicrobial peptides that may be used in antimicrobial compositions and articles.
摘要:
The invention describes application of pure culture microbial strains under denitrifying conditions for growth on crude oil thereby modifying crude oil properties to enhance its recovery.
摘要:
Disclosed herein is introduction of different nutrient solution formulations to a subterranean target site to prevent biofilm formation and biomass aggregation at the sand face of an injection well bore during MEOR or bioremediation processes. A first nutrient solution formulation supports growth of introduced microorganisms and a second nutrient solution formulation is used to promote biofilm formation to allow plugging of pores and channels in the subterranean target site, for MEOR or bioremediation.
