The virus is thought to have emerged after a human form of H2N2 combined with a mutant strain in ducks.
Validation of this model by culturing the mutant strain in this optimum medium exhibited similar values of PHB (7.76 g l−1), biomass (8.32 g l−1) and the PHB content in the cell 93.2% of DCW.
Batch DBT biodegradation experiments were carried out in a 7.5 L fermentor by the wild strain and its mutant strain in model oil system under different experimental conditions such as initial DBT concentration, resting cell density, and oil fraction (n-dodecane was used as the model oil because of its similarity to diesel oil).
To rule out the possibility that reduction of autophagy activity is due to the serine-to-alanine change, rather than loss of phosphorylation at S174, we generated a phosphomimic mutant strain in which serine 174 is replaced by aspartic acid (S174D).
The aim of this study was to compare the growth rates of a C. reinhardtii WT and mutant strain in monocultures and in competition (co-cultures) to evaluate the risk of the mutant strain escaping into the environment, as well as the industrial risk of losing the desirable phenotype of the mutant.
The results of the ACRS method revealed the YMDD mutant strain in 20 patients, YMDD plus YIDD pattern in 1 patient, YMDD plus YVDD in 4 patients, the YIDD in 4 patients and mixed infection with each three strains in 1 patient.
No phenotype was observed for the ΔiPGM mutant strain in these studies.
The significant role of the IPM in S. pneumoniae pathogenesis is indicated by the attenuated virulence of the mutant strain in intranasally infected mice [24].
To determine the number of replicates needed for each eat mutant strain in the feeding assay, the pilot study data were used in a mixed effects model [32].
This is consistent with the increased necrotic tissue observed earlier in leaves infiltrated with the mutant strain in which plant primary metabolism appeared to have slowed down.
Complementation of the ΔSPI-19 mutant strain in trans, restored the ability of this mutant to colonize the gut and internal organs of infected chickens.
