A Si-rich but conformal Cat-SiN thin film deposited with an NH3-deficient gas mixture of SiH4/NH3/H2 is used as the unit layer for the layer-by-layer Cat-CVD, with each layer followed by in-situ post-treatment in an NH3- and/or H2 ambient to cure the composition.
MtsABC-deficient GAS exhibit reduced growth rates in metal-depleted medium and under aerobic conditions (Janulczyk, Ricci and Bjorck 2003).
In contrast to wild-type GAS, Irr-deficient GAS were more rapidly killed after phagocytosis through enhanced sensitivity to solubilized neutrophil primary granules, which are composed of α-defensins, elastase and cathepsin G (Sorensen et al., 1997).
However, a study comparing a Mac-1-deficient mutant GAS strain to the wild-type and complemented strains demonstrated that native Mac-1 expressed by live GAS does not reduce ROS production or other neutrophil functions (Okumura et al., 2013).
Solutions are categorized as gas deficient when the oxidizer is completely consumed, solid deficient when the solid fuel is completely consumed, or stoichiometric when both oxidizer and solid fuel are completely consumed.
SD109, a mutant strain of Halobacterium sp. NRC-1 lacking the gas vesicle gene cluster, is deficient in gas vesicle formation.
Not surprisingly, many of the states with structurally deficient bridges have lower gas tax rates than other states.
More recently, a serotype M49 GAS strain deficient in Rgg decomposed more H2O2 and was more resistant to 4 mM H2O2-mediated killing, compared to the wild-type parental strain (Pulliainen et al., 2008).
Mutants constructed with interruptions in each of the gvp genes by a kanamycin cassette exhibited a partially or completely gas vesicle-deficient phenotype, indicating that all of the gvp genes are necessary for wild-type gas vesicle formation [ 11].
In the H. sp. NRC-1, due to genetic instability caused by transposition of insertion sequences, typically about 1% of colonies in a plate are gas-vesicle deficient and 0.1% are carotenoid deficient mutants [ 13].
