Described herein are novel methods for the acetyl transferase-catalyzed production of drimanyl-acetate compounds by the acetylation of the respective drimanyl alcohol sources performed in vitro or in vivo. Also described herein is the identification of enzymes having corresponding acetyl transferase activity from different microbial and plant sources. Also described herein is the provision of enzyme mutants derived from the newly identified enzymes. Further described herein is the provision of corresponding coding sequences of such enzymes and mutants, recombinant vectors, and recombinant host cells suitable for the production of such acetyl transferases and mutants and for performing the novel production methods of drimanyl acetate compounds. Still further described herein is a method of using such drimanyl acetates as intermediates for the production of odorant, flavor or fragrance or insect/pest control ingredients.

The present disclosure relates to mutated genes of the LUX operon and their use in producing autoluminescent plants and bacteria exhibiting improved light output.

The present invention relates to a process for producing of free fatty acids comprising a) hydrolyzing fatty acid feedstock with lipase and water in an amount sufficient to produce partial splitting of the fatty acid feedstock in a reactor; and b) mixing said partially split fatty acid mixture in a thermal splitter column under conditions of temperature and pressure effective to substantially complete the splitting of the fatty acid feedstock into free fatty acid and glycerol as by-product.

A method for preparing and applying immobilized enzyme nanogels includes oxidized sodium alginate and enzymes are dissolved separately in deionized water, mixed uniformly, and reacted to obtain immobilized enzyme nanogels; the aldehyde groups in oxidized sodium alginate react with the amino groups in the enzymes, forming imine bonds to immobilize the enzymes; forming nano-scale cross-linked polymer-based particles with a three-dimensional network structure, resulting in the immobilized enzyme nanogels; the surface of immobilized collagenase nanogels is modified with CXCR4 antagonist peptides, which can specifically block CXCR4 on the surface of T cells; the Schiff base bonds can selectively break in the acidic microenvironment of tumors, leading to collagen degradation and reduced extracellular matrix density; the modification enhances the chemotaxis and infiltration of T cells into pancreatic cancer tissues and can inhibit the metastasis of pancreatic cancer.

The present invention relates to a recombinant microbial cell for producing at least one compound having structural Formula III from at least one simple carbon source:

##STR00001## wherein the simple carbon source is selected from the group consisting of glucose, sucrose, xylose, arabinose, mannose and glycerol; and wherein the cell comprises a further genetic modification to increase production of L-lysine in the cell from at least one of the simple carbon sources.
