Biogas production from Opuntia stricta Haw.: microbial diversity and solid load influence on sludge recycle systems

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.
