  • Patent number: 7993905
    Abstract: The invention provides a device for adhering cells in a specific and predetermined position, and associated methods. The device includes a plate defining a surface and a plurality of cytophilic islands that adhere cells, isolated by cytophobic regions to which cells do not adhere, contiguous with the cytophilic islands. The islands or the regions or both may be formed of a self-assembled monolayer (SAM).

  • Publication number: 20110177564
    Abstract: Some aspects of this invention provide methods and bioreactors for converting a carbon source into a lipid. In some embodiments, lipid production is carried out in an aerobic fermentor and carbon dioxide generated during lipid production is converted into a carbon substrate by CO2 fixation in an anaerobic fermentor. In some embodiments, the carbon substrate generated by CO2 fixation is used as the carbon source for lipid production, thus achieving total carbon utilization in lipid production.

  • Publication number: 20100184693
    Abstract: A method has been developed to create databases of peptides having a desirable property, such as antimicrobial activity, based on analyzing a database of known peptides for a pattern statistically associated with an activity. One can determine a set of patterns that may be representative of a peptide having a desired characteristic or property, and evaluate a set of sequences against the set of patterns (grammars) to determine if the peptide sequence being evaluated has similar patterns to those of a peptide having the desired characteristic or property. The set of sequences being evaluated may include peptide sequences of a desired length comprising all or substantially all combinations of amino acids that conform to at least one of the set of patterns. Once the database is identified, the database may be processed in a pattern recognition procedure that identifies a set of patterns that could be understood as representative of a peptide having the characteristic of interest.
