Microbial consortia for programmable output via photoautotroph-heterotroph interactions

Self-sustained, safe, stable and scalable microbial consortia (S 5 MicroCon) are described. The microbial consortia are regulated by photoautotroph-heterotroph interactions and RNA aptamer-based gene circuits. A rapid, high-throughput method for engineering RNA aptamer-based gene circuits (e.g. riboswitches) is also described.

Field programmable gate array bitstream verification

Described herein are various technologies pertaining to confirming an integrity of a FPGA. A verifier circuit is placed into an FPGA bitstream to enable external verification of the FPGA configuration in real time without requiring readout of the FPGA configuration itself. Number generators are utilized to generate a key which is shared between the FPGA and an external verification component (VC). The key is utilized to configure an initial state of sequence registers respectively located on both the FPGA and the VC. When the FPGA is operating with an approved configuration, output from the sequence registers at the FPGA and the VC are the same.

Methods of designing programmable inducible promoters

Described herein is a method for identifying synthetic inducible promoters that have specified induction and/or repression for DNA binding proteins such as an allosteric transcription factor and an inducer molecule. The method includes an in vitro selection from an unselected polynucleotide library comprising a plurality of random degeneracies, and an in vivo selection to produce an induced promoter library. Produced is an induction table, which allows the selection of a promoter with specific induction and/or repression properties. Also included are biosensors containing the synthetic inducible promoters.
