Biotechnological process for hydrocarbon recovery in low permeability porous media

The present invention refers to a biotechnological process that enhances oil recovery of a 14 to 25 API Gravity oil contained in carbonate-containing and/or clayey sandstone porous rock systems with low permeability (7 to 100 mD), thus focused to petroleum wells associated to zones with low recovery factor. The process utilizes the indigenous extremophile microorganisms activity from the oil reservoir and an IMP culture, as well as its metabolites (gases, acids, solvents and surfactants), which improve oil mobility and are able to develop at 60 to 95° C. temperatures, 7 to 154.6 Kg/cm2 (100 to 2,200 psi) pressures and NaCl content from 5,000 to 45,000 ppm, in anaerobic conditions. The biotechnological process of the present invention includes: indigenous microorganisms sampling, collecting and characterization from the reservoir; formulation of culture media; selection, enrichment, activation and preservation of such microorganisms, as well as biostimulation (indigenous microorganisms) and bioaugmentation (IMP culture) to increase the metabolite production, useful for oil recovery in a porous media impregnated with oil in carbonate-containing and/or clayey sandstone porous systems, with one or several cycles and confinement periods from 5 to 10 days, to increase oil recovery. Experimental tests show that the biotechnological process of the present invention supplies an oil recovery increase up to 30%, additional to that obtained in secondary recovery processes.

A method for industrial production of biocatalysts in the form of enzymes or microorganisms immobilized in polyvinyl alcohol gel, their use and devices for their production

A method for the industrial production of the biocatalysts with biologically active material in the form of immobilized enzymes or microorganisms which are immobilized into the polyvinyl alcohol gel, and their use based on the fact, that the active biological material, formed by the mixture of free native or pretrated (aggregated) enzyme catalyst, or production microorganism, or part of them, and the polyvinyl alcohol gel, is used for their industrial production, the mixture is gelated and shaped in a stream of drying air at the temperature of 800C to 150C, considering the extent of the biologically active material, at the biocatalyst geometrical ratio of the surface to the volume kept larger than 7 mm'1, and consequently thus prepared biocatalysts can be cultivated or stored and then use in biotechnological processes in the conditions,; which ensure given biotechnological process higher productivity, higher production and enzymatic stability, long-term and repeated usage or definable process control with consequence easy separation of the biocatalyst. The industrial production device, providing optimization of the biological carrier volume and surface in dependence on biologically active material extent, consisting of a casting mechanism (17) mounted in front of a drying channel (2), through which a continuous conveyor belt (1) runs, is equipped with at least one casting head (17) with two rows of casting needle injectors connected to a pressure tempered tank (15) and a compressor (16), the conveyor belt (1) and a drying system - the source (4) of a drying air, which is blown by means of ventilator into an air distribution system (6) with incorporated heating elements (5),; which runs into the upper drying channel (2), and further the lower final drying channel (3) and a reswelling tank (7), between which a wiping and collecting device (9) is mounted, designed on the basis of mechanical wiping and high-pressure rinse.

Process for producing a rhamnolipid produced by pseudomonas or enterobacter using andiroba or murumuru seed waste

Process for producing a rhamnolipid produced by Pseudomonas or Enterobacter using andiroba or murumuru seed waste, pertaining to the sector of compounds containing monosaccharide radicals, consists of producing rhamnolipids by a biotechnological process using andiroba or murumuru seed waste, following oil extraction, as a substrate for a Pseudomonas aeruginosa, Enterobacter hormaechei or Enterobacter buriae line cultivated in a bioreactor with a non-dispersive aeration system for reducing foam, producing a rhamnolipid content of 10.5 g / L for Pseudomonas aeruginosa bacteria, in bioreactors carried out in a stirred tank with non-dispersive aeration using microporous membranes, particularly of silicone tubes, which allow oxygen to be supplied by diffusion. This type of aeration allows for various configurations, and in the embodiment of the invention, the porous membrane / tube was internally located in the liquid in the bioreactor in the form of a serpentine, under the following process conditions: pure oxygen with suitable pressure and flow rate to maintain O2 pressure in the bioreactor at 20% during the first 24 hours of the assay and stirring varying from 300 to 700 rpm, using 2 radial impellers and manual adjustment according to the decrease in the concentration of dissolved oxygen. The product produced has features that can be used primarily in the cosmetic industry due to its emulsifying, stability and non toxicity capacities.

Method for improving expression quantity of pichia pastoris foreign protein by using mercaptan peroxidase

ActiveCN103898142AContributes to correct conformational formationPromote secretionVector-based foreign material introductionPichia pastorisBiotechnology
The invention discloses a method for improving the expression quantity of a pichia pastoris foreign recombinant protein by using mercaptan peroxidase as a cofactor aiming at improving the preparation capability of the pichia pastoris foreign recombinant protein, belonging to the field of biochemical engineering. The method comprises the steps of connecting a mercaptan peroxidase gene with an inducible promoter or a constitutive promoter from pichia pastoris or saccharomyces cerevisiae to construct a gene expression vector, and transferring the gene expression vector to a methanol induced pichia pastoris strain for expressing the foreign recombinant protein to perform co-expression or over-expression, wherein the mercaptan peroxidase gene serving as a global control gene of oxidation reduction stress response improves the expression quantity of the foreign recombinant protein in the methanol induced pichia pastoris under the control effects of the promoter of different strengths and the transcriptional level of a gene copy number. The invention provides a new method for improving the capability of producing recombinant protein by cells and the bio-reaction efficiency, which has an important value for strengthening a biotechnology process.

Apparatus, methods and compositions for biotechnical separations

RNA, preferably messenger RNA, is purified by use of selective precipitation, preferably by addition of compaction agents. Also included is a scaleable method for the liquid-phase separation of DNA from RNA. RNA may also be recovered by fractional precipitation according to the invention. We have discovered that specific classes of compounds are unexpectedly potent in causing selective precipitation of DNA away from RNA, at low concentrations and in the presence of relatively elevated ionic strength. Modification of the selective removal of DNA can also remove both RNA and DNA, leaving behind a mixture which is advantageous for the further purification of, e.g., proteins. Additional aspects of the invention include mini-preps, preferably of RNA or of plasmid and chromosomal DNA to obtain sequenceable and restriction digestible DNA in high yields in multiple simultaneous procedures. Still further aspects disclose enhanced stripping of the compaction agent by a stripping method comprising high salt addition and pH shift, and combinations of these techniques. RNA Abstract Additionally, a new approach to the isolation of RNA from bacterial lysates employs selective precipitation by compaction agents. The above techniques can be enhanced by use of phase transfer catalysts (PTCs), most preferably selected polyamines of U.S. Pat. No. 6,617,108 polyamines which are quaternary compounds. (The use of PTCs in biotechnical processes is not evident in the literature, see e.g. www./ptorganics.com as of 27 Jan. 2005.)
