In this work we have explored the possibility of constructing a new chemically synthetic operon to transfer the capacity to produce isobutanol to different bacteria, allowing the possibility to test in a simple way many different host organisms as putative isobutanol producers and to regulate it in an integrated manner.
The screening for putative AHL producers has revealed that Gram-negative bacteria belonging to different genera which occupy a wide variety of environmental sources produce AHLs.
Identification of the Dhc genes active in methionine synthesis and transport will require targeted experiments examining transcriptomics or protein expression profiles under growth conditions lacking methionine and/or in co-cultures with the Firmicute genera highlighted here as putative methionine producers.
venter, was prolific in both systems as the putative dominant primary producer.
Putative acetic-acid producers Acetobacter spp. and Gluconacetobacter spp. are prevalent in pyrosequencing libraries derived from tank samples containing FGE and water.
Several NRPSs identified previously as putative siderophore metabolite producers (designated the SidE clade) [ 23], which fell in a clade just outside the major clade of known ferrichrome synthetases, were also included.
The fact that "Mamma Mia!" has been nicknamed "the Lourdes of musicals," according to one of its producers, Judy Craymer, for its putative effect on even infirm audience members -- "they throw down their walking sticks and start to dance," she said -- doubtless played a role in the decision to carry on.
A 1339 bp DNA fragment of the putative oriC region from the rifamycin SV producer Amycolatopsis mediterranei U32 was cloned by PCR amplification employing primers designed based on the conserved flanking genes of dnaA and dnaN.
Once upon a time, so-called respectable films opened in certain theaters, and the putative dross of the type churned out by the producer Samuel Z. Arkoff opened elsewhere.
Both processes are energetically costly and, consistently, 4.1% of whole ESTs and 7.4% of identified protein precursors match with components of the energy-producer organelle mitochondrion, whereas 2.7% and 4.4%, respectively, are putative homologues of proteins directly involved in the energy-producer oxidative phosphorilation or tricarboxilyc acid cycle.
