The phrase "attractive strain" is correct and usable in written English.
It can be used in contexts where you are describing a particular type of strain that is appealing or desirable, possibly in fields like biology, genetics, or even metaphorically in discussions about ideas or trends.
Example: "The researchers were excited to discover an attractive strain of bacteria that could potentially enhance crop yields."
Alternatives: "appealing variant" or "desirable type".
Thermotolerant Saccharomyces cerevisiae is widely regarded as an attractive strain with which to accomplish the coupling of enzyme saccharification, ethanol fermentation and ethanol distillation in non-grain fuel bioethanol fermentation systems, and it has many advantages for increasing the ethanol yield and reducing production costs.
Bacillus subtilis can efficiently secrete native or heterologous proteins into the culture broth, which renders it an attractive strain for enzyme production at an industrial level.
But we must be clear, as Merritt is, on the costs: to eschew traits is not only a departure from central strains of the virtue ethics tradition, it is a departure from an attractive strain of that tradition.
These macroscopic compressive and tensile zones occupying multiple near surface lattice sites offer a much more attractive strain relaxation centre compared to the individual atomic sites that lead to ordering.
In particular, Synechococcus sp. strain PCC 7002 (PCC 7002), an attractive strain for metabolic engineering due to its rapid growth rate, high CO2 fixation rate, and halotolerance, has very few promoters of known strength and only one reported inducible promoter.
Joel Weiss, as Tameem, has a thinnish, sometimes strained, but reasonably attractive tenor.
As costs of DNA sequencing decrease, sequenced-based approaches will probably become more attractive for strain typing in a near future.
One of these hybrids was further tested and shown to retain its superior fermentation performance on an 8-l pilot scale, making it an attractive candidate strain for commercial bioethanol production.
As a model in evolutionary genomics, S. meliloti is particularly attractive because strains of this species harbor large and typically multipartite genomes with a chromosome, a chromid, a megaplasmid, plus additional smaller plasmids (Krawiec and Riley 1990; Galibert et al. 2001; Galardini et al. 2011; Tian et al. 2012).
Therefore, it also constitutes an attractive target for strain engineering work.
Undoubtedly, further developments in functional genomics and other analytic techniques that lead to the discovery of many new signal transduction pathways and new transcription factors will reveal new, attractive targets for strain improvement approaches in the near future.
