摘要:
The invention provides a method for isolating and culturing a previously unculturable microorganism, which comprises: (i) collecting a sample from an environmental source; (ii) counting/estimating the number of microorganisms in the sample; (iii) diluting the sample in an appropriate medium; (iv) adding a gelating agent such as to entrap one or more microorganisms within a sphere of the gelating agent; (v) coating the spheres containing the entrapped microorganism(s) with a natural or synthetic polymer to form a polymeric membrane; (vi) incubating the coated spheres in the original environment for an appropriate time; (vii) cutting the spheres and scanning for microorganisms colonies; and (viii) isolating the microorganisms, and repeating steps (iii) to (vii) until a pure clone of said previously unculturable microorganism is obtained.

摘要:
A process is provided for purifying water containing soluble species capable of forming one or more sparingly soluble salts or minerals, comprising feeding a pressurized water stream into a treatment zone (2) having one or more membranes (M), passing the stream along the membranes (M) to recover permeate (4) and concentrate (3), while periodically reversing the flow direction at periods of time to prevent exposing the membranes (M) to supersaturation condition, thus preventing precipitation of the salts and minerals.
摘要:
SO-modified transgenic plants overexpressing or lacking SO activity, having modified tolerance or susceptibility to toxicity of sulfite-producing substances, methods for their production and the use thereof for bioremediation of pollutants, as sentinel plants, for enhancing post-harvest quality of plants, plant tissues and plant products and for therapeutic applications.
摘要:
A method of assessing the in vivo state of phagocytes in a patient, possibly indicating diagnostically important states such as inflammation or infection, which method utilizes chemiluminescent (CL) light emitted during the reaction in vitro between a CL substrate and the reactive oxygen species (ROS) formed in a fluid sample obtained from the patient. The measurement is performed in two or more portions of the sample, with stimulated phagocytes affected by one or more priming agents which shift the functional state of the phagocytes, providing a plurality of measurements, which are analyzed so as to distinguish intracellular and extracellular contributions to the CL kinetics. The results are compared with a range of control measurements performed with patients suffering from various diagnostic conditions.
摘要:
A process for producing a fuel composition from vegetable and/or animal oil comprises hydrodeoxygenating and hydroisomerizing the oil in a single step. The fuel composition has acceptable lubricity and comprises a mixture of C14 to C18 paraffins having a ratio of iso to normal paraffins of 2 to 8 and less than 5 ppm sulfur.
