Abstract: This disclosure provides engineered strains of Corynebacteria for the cost-effective production of lysine, tools and methods used to produce the engineered strains, and methods of using the engineered strains to produce lysine.

Abstract: Systems, methods and computer-readable media are provided for designing experiments for organisms at a first scale to generate first-scale performance data used in predicting performance of the organisms at a second, larger scale. The design includes determining first-scale screening conditions based at least in part upon the contribution of second-scale conditions to performance parameters of an organism at the second scale. The first-scale screening conditions include one or more proxies for second-scale conditions that cannot be replicated at first scale. The design determines first-scale screening parameters based at least in part upon computer modeling of the metabolism of the organism at the second scale.

Abstract: Systems, methods and computer-readable media storing executable instructions are provided for improving performance of an organism with respect to a phenotype of interest at a second scale based upon measurements at a first scale. First scale performance data based at least in part upon observed first performance of first organisms at a first scale and second scale performance data based at least in part upon observed second performance of second organisms at a second scale larger than the first scale are accessed. A prediction function based at least in part upon the relationship of the second scale performance data to the first scale performance data is generated. The prediction function may be applied to performance data observed for test organisms with respect to the phenotype of interest at the first scale to generate second scale predicted performance data for the test organisms at the second scale.

Abstract: Provided are native promoters comprising polynucleotides isolated from Corynebacterium glutamicum, and mutant promoters derived therefrom, which may be used to regulate, i.e., either increase or decrease, on-pathway and/or off-pathway gene expression. Also provided are promoter ladders comprising a plurality of the promoters having incrementally increasing promoter activity. Also provided are host cells and recombinant vectors comprising the promoters, and methods of expressing ancillary genes of interest and producing biomolecules using the host cells.

Abstract: Systems, methods and computer-readable media are provided for determining modifications to apply to genes within at least one microbial strain to improve phenotypic performance. The disclosure teaches accessing first phenotypic performance data based at least in part upon first gene modifications made to a first set of genes in at least one microbial strain; predicting second phenotypic performance of second gene modifications, based at least in part upon the first phenotypic performance data and at least one modification feature that is common to the first gene modifications and the second gene modifications; and prioritizing the second gene modifications to be applied to a second set of genes based at least in part upon the second phenotypic performance.

Abstract: The present disclosure provides a HTP microbial genomic engineering platform for Saccharopolyspora spp. that is computationally driven and integrates molecular biology, automation, and advanced machine learning protocols. This integrative platform utilizes a suite of HTP molecular tool sets to create HTP genetic design libraries, which are derived from, inter alia, scientific insight and iterative pattern recognition.

Abstract: The present disclosure is directed to a method of high-throughput (HTP) microbial genomic engineering, which utilizes in vivo transposon mutagenesis to develop strain libraries for the perturbation of microbial phenotypes.
