Lanthanides are recycled with microbes comprising a lanthanide-dependent alcohol dehydrogenase and an evo-HLn Methylorubrum extorquens AM1 hybrid sensor histidine kinase/response regulator comprising a Leu151His substitution relative to the wild-type.

UO.sub.2F.sub.2 biosensors, and related U-sensing and/or F-sensing genetic molecular components, genetic circuits, compositions, methods and systems are described, which in several embodiments can be used to detect and/or neutralize uranium and in particular bioavailable UO.sub.2F.sub.2.

The present invention relates to a novel Streptococcus thermophilus strain having improved texturizing properties, compositions comprising said strain as well as fermented products manufactured using said strain.

Methods to create two component signal transduction systems by replace the DNA binding domains and output promoters in bacteria are described.

The invention relates to mammalian cells comprising at least one prokaryotic two-component signaling (TCS) pathway comprised of an activator protein A, a response regulator (RR) protein B activated by said protein A, such activation leading to an activated RR protein B, and an output gene C operably linked to a promoter. Transcription from said promoter is activated by activated RR protein B, and the expression of output gene C defines at least a first state (0, no transcription) and a second state (1, detectable transcription). The invention further relates to logic gates designed from such cells, and methods for integrating a plurality of output signals based on the cells and logic gates of the invention.

A nitrate sensing biosensor and bacteria and applications relating to the use of same are described. The nitrate biosensor comprises a two component sensor system (TCS) comprising: a nitrate-sensing sensor kinase (SK) gene comprising a ligand binding domain operably coupled to a kinase domain, and, a cognate response regulator (RR) gene comprising a receiver domain operably coupled to an DNA binding domain (DBD), as well as an output promoter that binds said DBD that is operably coupled to a heterologous reporter gene.

UO.sub.2F.sub.2 biosensors, and related U-sensing and/or F-sensing genetic molecular components, genetic circuits, compositions, methods and systems are described, which in several embodiments can be used to detect and/or neutralize uranium and in particular bioavailable UO.sub.2F.sub.2.

Provided are improved fungal strains and use thereof, wherein the fungal strains are capable of producing an altered level of proteins, enzymes, variants and other substances of interest.

A novel technique for improving secretory production of a heterologous protein by coryneform bacteria is described, as well as a method for secretory production of a heterologous protein. A coryneform bacterium is described that has been modified to have a specific mutation so as to harbor a phoS gene, and when cultured, is able to to produce a heterologous protein by secretory production.

Provided in this disclosure are methods of treating a bacterial infection comprising administering a formulation comprising an antimicrobial peptide described herein when administered to a subject. Further provided herein are methods of treating a bacterial infection wherein the bacterial infection comprises a bacterium with a mutation in a gene resulting in antibiotic resistance.
