摘要:
An evolvable production strain of B. subtilis exhibiting continuous or high level expression during protein evolution is described. An evolved Bacillus subtilis pstS promoter facilitates screening and production of secreted proteins.
摘要:
Described herein are methods for obtaining from an initial population of cells a plurality of subpopulations of cells having a similar density by growing samples from the initial population in medium having a limiting nutrient. Also provided are methods for using such subpopulation of cells to identify members of an initial population, either spontaneously occurring or induced by mutagenesis, having altered and/or preferred phenotypes.
摘要:
A method for holding samples for analysis and an apparatus thereof includes a testing plate with a pair of opposing surfaces and a plurality of holes. Each of the holes extends from one of the opposing surfaces to the other one of the opposing surfaces. The holes are arranged in groups, where each group has at least two rows and two columns of holes. The groups are arranged in sets, where each set has at least two rows and two columns of groups. To analyze samples, at least one of the opposing surfaces of the testing plate is immersed in a solution to be analyzed. A portion of the solution enters openings for each of the holes in the immersed opposing surface. Once the holes are filled with solution, the testing plate is removed and is held above a supporting surface. Surface tension holds the solution in each of the holes. The solution in one or more of the holes is then analyzed and the solution in one of these holes is identified for further study. The location of the identified solution is marked based upon its location within a particular set and group of holes.
