Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
48 words
A method for making an incompetent unicellular microorganism host competent to utilize L-tartrate as a carbon source, said method comprising introducing in vitro a plasmid conferring the ability to utilize L-tartrate into the host, said plasmid being capable of expressing a tartrate catabolism gene derived from plasmid pTAR.
Claim 2
Independent Claim
48 words
A method for making an incompetent unicellular microorganism host competent to utilize L-tartrate as a carbon source, said method comprising introducing in vitro a plasmid conferring the ability to utilize L-tartrate into the host, said plasmid being capable of expressing a tartrate catabolism gene derived from plasmid pTAR.
Claim 3
Dependent Claim
16 words
An incompetent unicellular microorganism host made competent to utilize L-tartrate by the method of claim 1.
Claim 4
Dependent Claim
7 words
A prokaryotic host as in claim 2.
