Rapid depletion of natural resources with continued demands of an increasing population and high consumption
rates of today’s world will cause serious problems in the future. This, along with environmental
concerns, has directed research towards finding alternatives in variety of sectors including sustainable
and environmentally friendly consumer goods. Biopolymers of bacterial origin, with their vast range
of applications, biodegradability and eco-friendly manufacturing processes, are one of the alternatives
for a more sustainable future. However, the cost of their production is a drawback. Simultaneous production
processes have always been an option for researchers in order to reduce cost, but the variable
requirements of microorganisms to produce both different and valuable products are a hindering factor.
This review will look at some examples and identify ideas towards developing a successful strategy for
simultaneous production of bio-products.
100 mm long) were
cut from each type of paper and were tested using a double clamp
with a separation of 30 mm at a test speed of 20 mm/min. The clamp
separation was 100 mm and the strain rate was 20 mm/min. The
curve load vs. extension was recorded until the elongation at break
was reached. The TS was expressed in MPa and was calculated by
dividing the maximum load (N) by the cross-sectional area (m2).
Maximum elongation at break or percent elongation at break (%E)
was determined by dividing the extension at the moment of breakage
by the initial gauge length of the samples and multiplying by
