The present invention relates to methods of transforming a cell by use of an acoustic transducer. In particular embodiments, the radiofrequency signal to the transducer can be tuned to provide optimal membrane disruption of the cell; and an agent, such as a nucleic acid, can then be delivered to the cell.
Sandia National Laboratories will computationally evaluate several raceway pond design modifications for improved growth of Haematococcus pluvialis. Sandia National Laboratories will use the model to optimize design and growth conditions such as temperature, light, and CO 2 to make design and condition modification recommendations to the Requestor.
Previous strain development efforts for cyanobacteria have failed to achieve the necessary productivities needed to support economic biofuel production. We proposed to develop CRISPR Engineering for Rapid Enhancement of Strains (CERES). We developed genetic and computational tools to enable future high-throughput screening of CRISPR interference (CRISPRi) libraries in the cyanobacterium Synechococcus sp. PCC 7002, including: (1) Operon- SEQer: an ensemble of algorithms for predicting operon pairs using RNA-seq data, (2) experimental characterization and machine learning prediction of gRNA design rules for CRISPRi, and (3) a shuttle vector for gene expression. These tools lay the foundation for CRISPR library screening to develop cyanobacterial strains that are optimized for growth or metabolite production under a wide range of environmental conditions. The optimization of cyanobacterial strains will directly advance U.S. energy and climate security by enabling domestic biofuel production while simultaneously mitigating atmospheric greenhouse gases through photoautotrophic fixation of carbon dioxide.
