Energy recovery from the wastes collecting from a biorefining process for butyrate production
Abstract
A
novel
process
of
alkali-heat
pretreatment
-
mixed
culture
fermentation
was
proposed
to
produce
butyric
acid
from
rice
straw,
but
generating
waste
(PW)
and
(FW).
In
this
study,
the
feasibility
methane

confirmed,
with

The

optimized
at

also
verified

This
