Abstract: The present invention relates to processes for the production of microalgae, cyanobacteria and/or metabolites thereof. Described herein is a process involving, the use of a stimulus applied to a microalgal or cyanobacterial culture to enhance the production of one or more metabolites. Also described herein, is a process for the production of microalgae and/or cyanobacteria comprising an adaptation stage wherein an algal/cyanobacterial culture is grown on a process water feedstock and/or under light emitting diodes (LEDs) emitting light within the spectrum of light wavelengths between around 400 nm and 700 nm, and a production phase, wherein the microalgae or cyanobacteria are grown on the same process water feedstock and/or under the same light conditions used in the adaptation stage. The invention also relates to specific microalgal strains.

Abstract: A refiner disk or disk segment cast from a stainless steel alloy having a composition of 0.2 percent to 0.6 percent carbon, 0.5 to 1.5 percent manganese, 0.5 percent to 1.5 percent silicon, a maximum of 0.05 percent sulfur, a maximum of 0.05 percent phosphorus, 14 percent to 18 percent chromium, 2 percent to 5 percent nickel, 2 percent to 4 percent copper, a maximum of 1 percent molybdenum, 1.5 percent to 5.0 percent niobium, a maximum of 1.5 percent vanadium, and a maximum of 0.5 percent total of at least one element selected from either rare earth metals and/or magnesium, the balance being iron. The niobium and vanadium form discrete carbides at high temperatures during the melting process. The rare earth metals and/or magnesium enhances the toughness of the disk by helping to shape the carbides and control them as discrete particles. Upon cooling, the carbides are preferably distributed evenly throughout the structure.

Abstract: A refiner plate has bars integrally formed with the refiner plate base member which have discrete regions of selected physical properties. A material possessing the physical property is deposited in a reservoir in the bar, such as a groove. The reservoir may be positioned in the top of the bar and may be of various shapes. Alternatively, the reservoir with material is positioned on the bar leading or trailing edge. Alternatively, an abrasive surface extends over the entire upper surface of the bar including the leading and trailing edges. The bar may be formed of a white iron alloy which is heat-treated to form a soft matrix with embedded carbide grains. By protecting regions of desired smoothness with a wear-resistant protective coating flow is preserved in selected areas.

The Niobium forms discrete carbides at high temperatures during the melting process. Upon cooling, the carbides are distributed evenly throughout the structure. This resultant alloy provides toughness and corrosion resistance like a lower carbon alloy plus increased wear resistance due to the carbide formation. The alloy utilizes chromium to impart corrosion resistance, the process of tying up carbon as discrete, non-chromium carbides increases the amount of chromium present to provide corrosion resistance.

Abstract: A refiner disc employing sharply tapered refiner bars wherein the upper portion of at least one side tapers inward at thirty to sixty degrees from the vertical. The tapered refiner bars tend to wear sharp. A further embodiment employs refiner disc bars which have a substantially narrower bar forming the upper portion of a standard, substantially rectangular bar.
