PHA, a group of biobased microbial biopolyesters subjectable towards
biodegradation constitute promising candidates to potentially substitute diverse
conventional petrol-based plastics. As a drawback, PHA ́s too high production
cost still hampers their success on the on the market. The most prominent cost
generating factors are the upstream processing, the bioprocess (fermentation),
and, last, but not least, thus * Corresponding author Abhishek Dutt Tripathi:

Therefore, the success and efficiency of the bioprocess technology for the
economical m a iufactu ring of a biochemical is closely associated with the
integrated designing and operation of ill the three important steps—upstream
processing, ... In addition to the microbial cell cultures, plant animal cell cultures
are also used for the production of specific compounds like various enzymes,
organic compounds like alkaloids, flavanoids, PHA, vitamins, hormones, steroids,
pigments etc.

Owing to the enormous amounts available annually, lignocellulose-based wastes
are likely to become the most important raw materials for future biotechnological
production of polymers, chemicals and fuels. To make substantial progress in this
field, increased know-how is required in the areas of microbiology, enzyme
technology and chemical engineering to overcome still-existing bottlenecks in the
efficient conversion of these feedstocks, especially during the upstream

Cellulases catalyze the breakdown of cellulose fibers found in plant-based
materials, while pro- teases and esterases hydrolyze proteins and lipids, respec-
tively. ... Bioplastics include PHA, PLA, xanthan gum, and rubber. ... Continuous
fermen- tation is preferred for production of primary metabolites or proteins in
addition to any other molecules synthesized as part of normal cell function. nn
Downstream processing readies the products of upstream processing for their
final sale.

To date, more than 250 different PHAproducing bacteria ... Other biodegradable
polymers such as polylactide and starch-based polymers are in a similar situation
, in that their production cost are higher than those of conventional plastics.
Consequently, much effort has been devoted to reducing the production cost of
PHAs, the main aim being to develop upstream to downstream processes that
include the development of better bacterial strains, and more efficient
fermentation and ...
