  • Patent number: 11900286
    Abstract: Systems, methods, and computer program products for generating job value predictions by a trained model for a tenant include receiving live data associated with a tenant, where the live data includes information associated with a job to be performed by the tenant. A trained model associated with the tenant is retrieved, where the trained model is configured to generate a job value prediction for the job to be performed. The live data is preprocessed to obtain a set of features associated with the job, the set of features consumable by the trained model, and the trained model is applied to the set of features to generate the job value prediction for the job to be performed by the tenant.

  • Publication number: 20220041998
    Abstract: A method for biosynthesis of polymer precursors, including, adipic acid, 1,6-hexanediol, 6-hydroxyhexanoic and 6-aminocaproic acids from carboxylic acids is provided. A method for biosynthesis of adipic acid from six-carbon dicarboxylic acids having ?, ?-enoate reductase activity by treatment with an enzyme is provided. The biocatalytic conversion of aliphatic and hydroxycarboxylic acids to corresponding aldehydes, alcohols, and amines using novel carboxylate reductases, aldehyde reductases, and aminotransferases is described. Also provided are genetically engineered microorganisms for use in the biosynthetic processes.

  • Publication number: 20200325499
    Abstract: A non-naturally occurring microorganism having a 1,3-BDO pathway is provided. The microorganism expresses at least one of the following 1,3-BDO pathway enzymes: an aldolase that catalyzes condensation of two acetaldehydes to produce 3-hydroxybutanal; and an aldo-ketoreductase, oxidoreductase, aldehyde reductase or alcohol dehydrogenase that reduces 3-hydroxybutanal to 1,3-BDO. The organism may further express one or more enzymes for producing acetaldehyde. A biosynthetic process involves condensing two acetaldehyde molecules to 3-hydroxybutanal using an enzyme from class aldolases; and selectively reducing 3-hydroxybutanal to 1,3-BDO using an enzyme belonging to the class aldo-ketoreductase, oxidoreductase, aldehyde reductase or alcohol dehydrogenase. The process can further include producing acetaldehyde by a biosynthetic method.
