Title: Bag Structure and Pad
Inventor: SETTON SIMON
IPC: B65D81/26
Filed: 1994-03-04
Abstract: A bag for packaging food products that exude juices, such as meat and poultry, incorporates therein an  absorbent  pad  which  is  sandwiched  between  an impervious  surface  layer  and  a  pervious  layer  and retained against a lower section of the rear side wall of the bag   by a retention strip made of bondable material.  The retention strip may be a strip of heat-fusible material or an adhesive tape.   The retention strip extends transversely across the rear side wall and an uppermost edge of the pad, and if heat-sealed, two  fused lines  are  formed.   The  first  fused line extends  longitudinally  along  a  leading  edge  of  the retention strip and forwardly of the uppermost edge of the pad.   A second fused line extends longitudinally across the strip, over the top impervious surface layer of the pad and on the bag rear side wall of both sides of the pad.   This strip maintains the pad in position in the lowermost section of the bag and prevents the disturbance and withdrawal of the pad when the food products are inserted and removed from the bag.

Title: Degradation of nucleic acid by peroxides to reduce viscosity
Inventor: GREER WILLIAM
IPC: C12N1/08
Filed: 1993-10-27
Abstract: Peroxide, particularly supplied as hydrogen peroxide, is an effective nucleic acid degrading agent and can be used in the recovery of intracellularly produced materials from cell (particularly bacterial) lysates. The degradation or removal of nucleic acids from cell lysates is important because they form solutions of high viscosity which interfere with subsequent processing. Peroxide degradation is particularly useful in the recovery of polyhydroxyalkanoate polymers such as polyhydroxybutyrate/valerate from lysates of bacterial cells in which they are produced.
