  • Publication number: 20240117297
    Abstract: A p-aminobenzoic acid-producing microorganism is provided. The p-aminobenzoic acid-producing microorganism is obtained by a method for preparing a p-aminobenzoic acid-producing microorganism. The method for preparing a p-aminobenzoic acid-producing microorganism includes (a) performing an acclimation process on a source microorganism with at least one sulfonamide antibiotic to obtain at least one acclimatized microorganism and (b) screening out at least one p-aminobenzoic acid-producing microorganism from the at least one acclimatized microorganism, wherein the at least one p-aminobenzoic acid-producing microorganism has a higher p-aminobenzoic acid titer than the source microorganism.

  • Patent number: 11934480
    Abstract: A circuit for in-memory multiply-and-accumulate functions includes a plurality of NAND blocks. A NAND block includes an array of NAND strings, including B columns and S rows, and L levels of memory cells. W word lines are coupled to (B*S) memory cells in respective levels in the L levels. A source line is coupled to the (B*S) NAND strings in the block. String select line drivers supply voltages to connect NAND strings on multiple string select lines to corresponding bit lines simultaneously. Word line drivers are coupled to apply word line voltages to a word line or word lines in a selected level. A plurality of bit line drivers apply input data to the B bit lines simultaneously. A current sensing circuit is coupled to the source line.

  • Publication number: 20220339681
    Abstract: A biodegradable composite includes an organic matter and a porous material, wherein the organic matter has viable bacteria, and a total plate count of the organic matter is greater than or equal to 104 CFU/g. The organic matter accounts for 40% to 80% of a weight of the biodegradable composite. The porous material accounts for 20% to 60% of the weight of the biodegradable composite. The biodegradable composite could instantly remove unpleasant odor and accelerate a decomposition process to form compost. A product containing the biodegradable composite is provided as well.
