Dysregulated biosynthesis and hydrolysis of cyclic-di-adenosine monophosphate impedes sporulation and butanol and acetone production in <i>Clostridium beijerinckii</i> NCIMB 8052.

ABSTRACT:

Introduction

Although solventogenic Clostridium species (SCS) produce butanol, achieving high enough titers to warrant commercialization of biobutanol remains elusive. Thus, deepening our understanding of the intricate cellular wiring of SCS is crucial to unearthing new targets and strategies for engineering novel strains capable of producing and tolerating greater concentrations of butanol.

Methods

This study investigated the potential role of cyclic-di-adenosine monophosphate (c-di-AMP) in regulating solvent biosynthesis in C. beijerinckii NCIMB 8052. Genes for c-di-AMP-producing and degrading enzymes [DNA integrity scanning protein A (disA) and phosphodiesterase (pde), respectively] were cloned in this organism and the recombinant strains were
