In addition and considering an already industrial scaled
strain such as Azahydromonas lata (formerly known as
Alcaligenes latus) which reaches its high PHB content (88%
of CDM) with ammonium limitation (Quillaguam an et al.
2008), B. megaterium uyuni S29 is not far from this result.
It has to be considered that A. lata has been studied for a
long time, and its optimal fermentation conditions are
being constantly improved. In comparison, the percentage
reached with strain uyuni S29 (70% of CDM) was obtained
from a shaking flask experiment with feed-batch fermenta-
tion, where the conditions were not completely optimal.
Therefore, it is very important to continue the research
with bacterial strain B. megaterium uyuni S29 to further
improve its PHB content.
