摘要:
Biological reactions are carried out with a unitary structure, preferably formed of a ceramic material, having a plurality of flow passages including first and second sets of flow passages arranged so that individual passages of the first set are adjacent individual passages of the second set and are separated by walls formed of the ceramic material. The ceramic material is porous to provide mass transfer of gaseous oxygen and biological reaction products while containing liquid in the second set of passages. Walls of the passages may be covered with a gaseous oxygen permeable membrane. Inside walls of the second set of passages may coated with a compound adapted to immobilize biological reaction materials. In a biological reaction, the first set of passages are contacted with a fluid such as an air stream to provide gaseous oxygen, and a fluid flow such as a nutrient medium is established through the second set of flow passages whereby an oxygen flow producing gradient is produced through the porous ceramic material between the first and second sets of flow passages to supply oxygen for cells immobilized on inside walls of the second set of flow passages.

摘要:
Methods to create databases of peptides having a desirable property, such as antimicrobial activity, involving analyzing a database of known peptides for a pattern statistically associated with the desirable property are described herein, The set of sequences being analyzed may include sequences of a desired length containing 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 may be representative of a peptide having the desirable property. A set of newly generated peptides sequences may then be processed to score these new sequences against the identified patterns to correlate the patterns to the sequences and determine a degree of association or similarity between one or more of the new sequences and the set of identified patterns.

The present invention relates generally to the use of droplets to culture and/or assay cells or other species. In some cases, the cells or other species may be sorted based upon the results of the culture and/or assay. In some embodiments, cells other species can be encapsulated in droplets and exposed to one or more agents (e.g., a sugar, an indicator dye, etc.). For instance, in some cases, exposure of cells to the agents may result in the production of metabolites or other compounds (e.g., amino acids, proteins, organic acids, etc.) which may be, for example, assayed or otherwise determined. In some embodiments, the reaction of an agent with cells and/or other species within a droplet may reveal a property of the cells or other species (e.g., sugar consumption, growth rate, ability to withstand exposure to the agent, etc.). As an example, cells that produce desired metabolites or exhibit certain properties may be separated from the other cells via sorting techniques. Other aspects of the invention relate to devices or kits for implementing such sorts, methods of promoting such techniques, or the like.

摘要:
A method for producing a C1-5 hydrocarbon from a solution containing a C2-6 carboxylic acid or a C2-6 carboxylate which is derived from biomass by contacting the solution with a solid catalyst to decarboxylate the C2-6 carboxylic acid or the C2-6 carboxylate, thereby forming a C1-5 hydrocarbon.
