Patent CA-2811297-A1 (CA)
Inventor: O'KEEFE DONALD
IPC: C12P1/00
Filed: 2011-09-23
Abstract: A method for recombinantly expressing a macromolecule in a host cell is disclosed which involves culturing a host cell which contains two nucleic acid sequences, i.e., a first nucleic acid sequence encoding a membrane-permeabilizing agent and a second nucleic acid sequence encoding a desired macromolecule under the operative control of an inducible promoter, to a selected cell density that permits accumulation of the agent. Thereafter the host cell is exposed to an environmental condition that induces the agent to disrupt the integrity of the cell membrane without complete lysis of the cell membrane. The host cell thereby allows transport through the membrane of small molecular weight compounds. These resulting host cells are cultured in the presence of a nutrient cocktail that contains components that can transport through the disrupted cell membrane, e.g., an inducing agent that induces the tightly regulated promoter and metabolic requirements that permit expression of the macromolecule. Alternatively, a method for enhancing recombinant expression of a macromolecule in a host cell comprises contacting a host cell at a suitable cell density with a membrane-permeabilizing agent that disrupts the integrity of the cell membrane without complete lysis of the membrane, and allows transport through the membrane of small molecular weight compounds. The host cell contains a nucleic acid sequence encoding a macromolecule under the operative control of an inducible promoter. These cells are then cultured in the presence of an above-described nutrient cocktail, and permits enhanced expression of the macromolecule in the membrane-disrupted host cell. Each method can also be employed in methods for in situ drug screening, among other uses.

Abstract: The invention relates to a device (1) for automatically and mechanically processing pieces of meat (6) conveyed in a row, comprising a transporting apparatus (2), a cutting apparatus (3) having a cutting head (31), and a control apparatus (5). The cutting apparatus (3) has a retaining and guiding apparatus (4), on which the cutting head (31) is movably arranged in order to carry out separating cuts at an angle from the straight conveying direction (20) along a straight movement path (40) at a fixed guiding tilt angle (a). A conveyor belt (21), which forms a component of the transporting apparatus (2) and which transports the pieces of meat (6) while said pieces of meat lie on the conveyor belt, continuously passes by the retaining/guiding apparatus (4). The cutting element (32) is formed by a rotationally driven circular blade (321) that is limited in order to cut at the height position thereof over the conveyor belt (21). While the separating cuts are being made, the control apparatus (5) correlates a velocity component (VT) of the movement velocity of the cutting head (31) in the conveying direction (20) with the conveying velocity of the pieces of meat (6) in the conveying direction (20). The device (1) is used in particular to skin fish fillets (60), wherein a tail end piece (610) is removed from the fish fillet (60) by means of a chamfer cut, which produces a filet end chamfered at a slant as an insertion aid for drawing skin (64) to be removed into the draw-in gap of a skinning machine.
