Device for detecting microorganisms

       An apparatus and method for mixing/agitating microorganism culture bottles includes a wheel in which culture bottles are placed, with the wheel being set at an angle from vertical so that bottles are not inverted during rotation. A sensor such as a florescence or colorimetric sensor for carbon dioxide is disposed along the flat bottom surface of each of the bottles. Once during each revolution the bottles pass across a photodiode/light emitting diode pair (for a calorimetric system). A sensor transmits light emitted by the LED to the photodiode. At the same instant, an infrared reflective objective sensor, emitting on a digital rotary encoder, determines the bottle number. The change in sensor transmittance is directly related to cell growth so that bottles positive for growth can be detected by suitable software.

Method of biological permeability modification of oil reservoirs using resident microorganisms and nutrient supplementation

       A method of increasing oil recovery from oil reservoirs includes the step of conducting a series of lab analysis that lead to a specific nutrient formulation followed by or in parallel with a genetic analysis of resident microorganisms in water produced from an oil reservoir to determine if the population of oil interactive microorganisms may be modified to produce a change in oil-water relative permeability of an oil reservoir. The series of analyses are conducted to determine the contents of a specific nutrient formulation package to optimize changes in the resident microorganisms to enhance oil recovery by changing oil-water relative permeability in the oil reservoir. Next the specific nutrient formulation is applied to stimulate some of the resident microorganisms to interact with oil contained in the reservoir rock formations. The stimulation step is followed by limiting the specific nutrient formulation to alter or modify the physiology and surface characteristics of the targeted microorganisms.

Ammonia-specific 5'-XMP aminase mutant

       Disclosed herein are ammonia-specific 5'-XMP aminase mutants and a method for preparing the same. A mutation is introduced into the active site of glutamine-dependent catalysis in 5'-XMP aminase. The resulting 5'-XMP aminase mutant is devoid of the glutamine-dependent activity and specifically reacts with external ammonia in converting 5'-XMP into 5'-GMP. Thus, the ammonia-specific 5'-XMP aminase mutant is stabler within cells compared to the wild type, and can be useful in the industrial conversion of 5'-XMP into 5'-GMP.
