A "parental strain" (E. coli BW25113) was more resistant than its isogenic single-gene deleted katG− mutant (E. coli JW3914) towards photocatalytic inactivation using TiO2 irradiated by UVA lamps (λ = 365 nm) in a partition system, whereas the photocatalytic inactivation efficiency of both bacterial strains were similar in a non-partition system.
The 41,723 bp multiresistance plasmid pMET1 (GenBank accession number EU383016) includes the replication region, a type 4 secretion system (T4SS), a partition system, and a transposable element that includes two genes coding for aminoglycoside modifying enzymes and two β-lactamases.
We designed a PDMS blood partitioning system based on the partition coefficients of chemicals between PDMS and major blood components.
Much like other secondary chromosomes and plasmids of Burkholderia species, they presumably depend on a ParA/B partitioning system [ 29].
Trial and error is still a needed approach in many applica tions to locate an optimal partitioning system and its operating conditions.
Thereafter, an organic aqueous partitioning system was applied for the purification of the biogenic Te NRs and the purified Te NRs were characterized using transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), X-ray diffraction spectroscopy (XRD), UV visible spectroscopy, and Fourier transform infrared spectroscopy (FTIR) techniques.
All 60 plasmids >10 kb encode some partitioning function: 78% have a homolog of the pSK1 par locus (Simpson et al. 2003), 12% have a type Ib partitioning system, and 10% have a type II system (Table S2).
The construct was stabilized by a previously established partitioning system.
Thus, the microorganisms could be absorbed closely on the surface or inner cover of carrier easily, and could contact with fermentation broth and solid substrate simultaneously to form a two-phase partitioning system employing liquid and solid phases.
A. actinomycetemcomitans utilizes a unique carbon resource partitioning system whereby the presence of L-lactate inhibits uptake of glucose, thus allowing preferential catabolism of L-lactate.
