The invention relates to a synthetic phytase with elevated thermostability, elevated stability to acids at p H 2, elevated stability to pepsin and with a broadened active p H range, and to an isolated nucleic acid sequence coding for a synthetic phytase and to the use of the phytase in an animal feed for reducing the phosphate content in the slurry and to animal feed additives and animal feeds comprising the synthetic phytase.

Synthetic phytase variants

A multistage process for producing mineral oil from mineral oil deposits by injecting aqueous flooding media into a mineral oil formation through injection boreholes and withdrawing the mineral oil through production boreholes, in which the mineral oil yield is increased by the use of microorganisms in combination with measures for blocking highly permeable zones of the mineral oil formation.

Multistage process for producing mineral oil using microorganisms

A process for producing mineral oil from mineral oil deposits by injecting aqueous flooding media into a mineral oil formation through injection boreholes and withdrawing the mineral oil through production boreholes, wherein the process comprises several cycles of process steps in which oil-mobilizing microorganisms and flooding water are injected alternately into the deposit. Processes in which highly permeable regions of the mineral oil formation are additionally blocked.
