  • Publication number: 20230222581
    Abstract: The Reinforcement Learning Based Machine Asset Planning and Management Apparatuses, Processes and Systems (“MRLAPM”) transforms machine learning training input, order optimization input, withdrawal policy optimization input datastructure/inputs via MRLAPM components into machine learning training output, order optimization output, withdrawal policy optimization output outputs. A machine learning training request datastructure structured to specify a set of agent profile datastructures and an agent sample ranking function is obtained. An agent samples range is determined. A set of inverse reinforcement learning (IRL) training sample datastructures is generated. An optimal reward function having a determined reward function structure is determined using an IRL technique on the set of IRL training sample datastructures. An optimal policy is determined using a reinforcement learning technique and the optimal reward function.

  • Patent number: 8003356
    Abstract: Methods for the microbial production of para-hydroxycinnamic acid (pHCA) and cinnamic acid (CA) are provided. Microbes producing either tyrosine or phenylalanine are grown in the presence of either tyrosine ammonium lyase or phenylalanine ammonium lyase respectively where some part of the fermentation is accomplished at alkaline pH. The process results in greater yields and higher rates of para-hydroxycinnamic acid (pHCA) and cinnamic acid (CA) production as compared with fermentation exclusively at physiological pH.

  • Patent number: 7998702
    Abstract: An L-arabinose inducible expression system comprising a mutant arabinose promoter. This system exhibits an increase in heterologous protein production upon induction with L-arabinose and comprises a mutant araB promoter and an AraC transcription binding region. This system retains the tight regulatory control characteristic of the wild type arabinose operon.

  • Publication number: 20080182307
    Abstract: A biocatalytic method for preparing para-hydroxystyrene from para-hydroxycinnamic acid is described. The method uses an enzyme source having para-hydroxycinnamic acid decarboxylase activity to catalyze the decarboxylation of para-hydroxycinnamic acid in a biphasic reaction medium to produce para-hydroxystyrene, which is extracted into the organic phase of the biphasic reaction medium. The method results in a high yield of para-hydroxystyrene due to the decreased exposure of the enzyme source to the inhibitory product. The product is readily recovered from the extractant, or may be chemically derivatized directly in the extractant before recovery.

  • Patent number: 6855867
    Abstract: This invention relates to an isolated nucleic acid fragment encoding a histidine biosynthetic enzyme. The invention also relates to the construction of a chimeric gene encoding all or a portion of the histidine biosynthetic enzyme, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the histidine biosynthetic enzyme in a transformed host cell.

  • Publication number: 20020164706
    Abstract: The invention relates to the field of microbiology. More specifically, methods are provided for the identification of highly expressed genes and their corresponding promoters and UV responsive genes and their corresponding promoters in cyanobacteria Synechocystis sp. PCC6803. These genes and promoters can be used to construct expression vectors in cyanobacteria, green algae or plants, for the production of biomaterials from sunlight, a renewable energy resource.
