Experiments carried out during early stationary phase cultures (a carbon starvation condition that provokes a rapid PHA degradation) of P. oleovorans and its phaZ minus mutant showed that the mutant strain was more sensitive to heat and oxidative shocks than the wild type. In P. putida, impaired survival and resistance to oxidative stress of an rpoS mutant was shown under conditions inducing PHA accumulation (Raiger-Iustman and Ruiz 2008). 

The PHAs are deposited as unique water-insoluble inclusions and when a carbon source is accessible in excess, while other nutrients are growth limiting (Figure 3.2). With carbon starvation, the polyester serves as a reserve polymer, which is then mobilized by intracellular PHA depolymerases, found to be attached to the granule surface [7]. At present, over 88 different polyester synthases are identified, cloned, and assigned [15,16]. 

Adenylated thiamin derivatives have only been recently discovered (Bettendorff et al. 2007 Frederich et al. 2009). AThTP is foimd in several tissues (mammalian liver and heart, roots of higher plants, etc. but it is not as widespread as ThTP. It is very often found in cultured cells. In E. coli, it is produced in response to carbon starvation and may reach up to 15% of total thiamin (Gigliobianco et al. 2010). AThDP was only found in low amounts in rodent liver and in E. coli.
