Hemanshu Mundhada has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11407976
    Abstract: The present invention generally relates to the microbiological industry, and specifically to the production of L-serine or L-serine derivatives using genetically modified bacteria. The present invention provides genetically modified microorganisms, such as bacteria, wherein the expression of genes encoding for enzymes involved in the degradation of L-serine is attenuated, such as by inactivation, which makes them particularly suitable for the production of L-serine at higher yield. The present invention also provides means by which the microorganism, and more particularly a bacterium, can be made tolerant towards higher concentrations of serine. The present invention also provides methods for the production of L-serine or L-serine derivative using such genetically modified microorganisms.

  • Patent number: 10822627
    Abstract: The present invention relates to a hydantoinase having an amino acid sequence selected from (i) or (ii), with (i) amino acid sequence selected from SEQ ID NO: 6-20 and SEQ ID NO: 73-119 (ii) amino acid sequence wherein in the amino acid sequence of SEQ ID NO: 6-20 and SEQ ID NO: 73-119, 1 to 75 amino acid residues have been substituted, deleted, inserted and/or added, and wherein further the catalytic activity of the hydantoinase is higher by a factor of at least 1.2 than the catalytic activity of the hydantoinase having amino acid sequence SEQ ID NO: 1. The present invention further relates to a process for preparing amino acids, wherein said hydantoinase is used.

  • Publication number: 20190367930
    Abstract: The present invention generally relates to industrial microbiology, and specifically to the production of biochemical compounds, such as L-serine, L-tyrosine, mevalonate and their derivatives, and recombinant polypeptides using genetically modified microorganisms. More particularly, the present invention pertains to the decoupling of cell growth from production of biochemical compounds, such as L-serine, L-tyrosine, mevalonate and their derivatives, in a microorganism by down regulating the nucleotide biosynthesis in said microorganism.
