Evaluating the potential for improving anaerobic digestion of cellulosic waste via routine bioaugmentation and alkaline pretreatment
… were investigated. The first method was routine bioaugmentation and the second was alkaline pretreatment. Both of these methods were applied to a two-phase anaerobic digestion process for treating the residuals from sweet corn processing, which have a significant lignocellulosic fraction as well …

The Effect of Select Biological and Environmental Factors on the Horizontal Gene Transfer and Functionality of the TOL Plasmid: A Case Study for Genetic Bioaugmentation
… microbes that have high degradation potentials (bioaugmentation). Although in situ bioremediation processes generally offer more advantages than ex situ methods, there are concerns with the current in situ methods that limit their effectiveness. For example, a major concern in bioaugmentation is …

Evaluation of anaerobic membrane bioreactors and hydrothermal catalytic gasification for enhanced conversion of organic wastes to renewable fuels
… anaerobic digesters. In this paper, routine bioaugmentation—the repeated addition of externally cultured microorganisms into the process stream—was tested as a means to increase hydrolysis and acid-production with the aim of thereby improving methane yields. The effects of bioaugmentation …
