  • Patent number: 8163871
    Abstract: Conversion in vitro of X-Gly to X-alpha-hydroxy-Gly or X-NH2 (X being a peptide or any other compound having a carbonyl group capable of forming a covalent bond with glycine) is accomplished enzymatically in the presence of keto acids, or salts or esters thereof, to provide a good yield without the necessity of catalase or similar enzymatic reaction enhancers. Peptidylglycine ?-amidating monooxygenase (PAM) is a preferred enzyme for catalyzing the conversion. Alternatively, peptidylglycine ?-hydroxylating monooxygenase (PHM) is utilized to convert X-Gly to X-alpha-hydroxy-Gly which may be recovered, or optionally may be simultaneously or sequentially converted to an amide by either a Lewis base or action of the enzyme peptidyl ?-hydroxyglycine ?-amidating lyase (PAL). Both PHM and PAL are functional domains of PAM.

  • Patent number: 8148120
    Abstract: Disclosed are methods that can advantageously utilize the natural consumptive and conversion processes of an aquatic organism culture system to concentrate and separate microbial plant-generated lipids. For instance, an aquatic organism culture can be maintained and/or grown upon an algal biomass. The natural conversion processes of the animals allows for uptake and processing of the components of the algal biomass into animal lipid. The aquatic animal culture can then be easily harvested such that a high percentage of the converted algal-generated lipid can be extracted using a low cost, simple and quick process. The disclosed processes provide an efficient oil production, conversion and recovery system that can be economically scaled up for use in, for example, integrated bioenergy and biodiesel production.
