Mar 30, 2001

Appl. No.:

09/828576

Inventors:

Jillian F. Banfield - Berkeley CA
Thomas M. Gihring - Madison WI
Robert J. Hamers - Madison WI

Assignee:

Wisconsin Alumni Research Foundation - Madison WI

International Classification:

B09B 300

US Classification:

4352625, 423DIG 17

Abstract:

A method for converting arsenite in a source to arsenate is disclosed. The method involves incubating bacteria of a Thermus species in the source at a temperature at which the bacteria can convert at least some of the arsenite to arsenate.

International Classification:

Abstract:

A technique is presented for the sequential extraction of nearly pure metal sulfides from solutions containing a mixture of metals, such as acid mine drainage. The technique is based on analysis of naturally occurring biofilms that selectively concentrate zinc, in zinc-sulfide, from a complex natural groundwater solution associated with a subsurface metal-sulfide mine. It was predicted and shown experimentally that release of sulfide ions, due to the activity of sulfate reducing bacteria, leads to sequential precipitation of pure metal sulfide phases from a solution of mixed metal ions, so long as the rate of production of sulfide ions does not exceed the rate of supply of the metal ions. This observation makes possible the design of biochemical processes to harness sulfate-reducing bacteria to separate and recover metals from mixed-metal waste streams.

Abstract:

The present disclosure provides a transposon system comprising: i) a nucleotide sequence encoding polypeptides that form a CRISPR-associated transposase complex; ii) a nucleotide sequence encoding a guide RNA; and iii) a transposon, or an insertion site for a transposon, flanked by CAST complex recognition sites. The present disclosure provides a prokaryotic cell comprising a subject transposon system. The transposon system is useful for editing the genome of a target prokaryotic cell. The present disclosure provides methods for editing the genome of a target prokaryotic cell. The present disclosure further provides systems and methods for identifying, within a heterogeneous population of prokaryotic cells, prokaryotic species that are susceptible to genetic modification and gene editing.
