Dextran produced by a natural isolate of Pediococcus pentosaceus, screened from Assam, in the Northeastern region of India, was estimated, purified, structure characterised and functionality analysed.
This prompted a more general concern that in a natural isolate, where the parasite population is heterogeneous, the nested PCR with mutation-specific primers technique can produce erroneous results that underestimate the complexity of the sample.
Two bacterial strains, the natural isolate Arthrobacter sp. FG1 and the engineered strain Pseudomonas putida PaW340/pDH5, were compared for their efficiency in the degradation of 4-chlorobenzoic acid in a slurry phase system.
A natural isolate of S. epidermiditis is highly resistant to tellurite.
The FMDV C-S8c1 is a plaque-purified derivative of the natural isolate C1-Sta Pau-Spain 70, a representative of the European subtype C1 FMDV [55].
To further test the role of genetic background, we mutagenized a highly divergent natural isolate (CB4856 from Hawaii) carrying the xol-1 mutation.
We used flies from the CS colony for the observations of courtship and aggression and used the natural isolate for all other observations.
FMDV C-S8c1 is a plaque-purified virus of the European serotype C, natural isolate C1 Santa-Pau Spain 70 [25].
The choice of a natural isolate can be based on having the closest sequence to all others, or picking a strain derived from acute infection and arguing that there is a convergence of viral sequences during transmission[7].
Thus the use of a single natural isolate for a vaccine has a high risk of not protecting against a different clade, nor against many variants of the same clade.
Two genomes of P. chrysogenum have been sequenced: one from an industrial strain, here termed "vdB" [7], and one from a natural isolate of the fungus that we sequenced as part of a graduate class on genome sequencing at UC Berkeley, here termed "UCB".
