Preface
Microbial strain engineering is used to improve production of bioproducts. Classical strain
engineering is performed by repeated cycles of random mutation and selection. These
methods have greatly contributed to strain improvement, but have serious drawbacks.
Uncharacterized “non-specific” secondary deleterious mutations will be introduced into
the genome during each mutagenesis cycle, and accumulate in the selected strain. Classical
methods also do not allow the introduction of new genetic material and are not suitable
for complex strain development applications such as metabolic engineering of organisms
to enable cell-based conversion of biomass into biofuels.
For complex strain engineering projects such as metabolic engineering for biofuels
production, a starting point “chassis” organism must be selected. This may be a commonly
used industrial organism such as Escherichia coli or Sacharromyces cerevisiae. While these
industrial organisms are not inherently adapted for production of biofuels, new genes and
functions can be rapidly imported using existing comprehensive strain engineering toolkits.
Many of these methods draw upon the fully annotated genome sequences of E. coli and
S. cerevisiae that ushered in a new age of rationale design-based strain engineering.
Alternatively, a native organism with existing biochemical pathways and production
potential for biofuels is selected as the chassis. However, native strains often are not
adapted for industrial fermentation and lack existing molecular biology tools necessary for
efficient strain engineering.
Recently, fully annotated genome sequences of many important native microbial
organisms have become publically available as a resource for researchers. The availability
of these genomic resources will enable adaptation of E. coli or S. cerevisiae-based rationale
design strain engineering methods to native organisms.
In this book, powerful new genetic engineering-based strain engineering methods are
presented for rational modification of a variety of model organisms. These methods are
particularly powerful when utilized to manipulate microbes for which sequenced and
annotated genomes are available. Collectively, these methods systematically introduce
genome alterations in a precise manner, allowing creation of novel strains carrying only
desired genome alterations.
In Section 1, E. coli-based bacterial strain engineering strategies are reviewed. State-of-
the-art methods for targeted gene knockout are presented, as well as their sequential
application for scarless genome modification. Methods for random gene knockout by
transposon mutagenesis are also described.
Cutting edge methods for identification of adaptation-selected genes are presented in
chapters describing genome engineering using oligonucleotide-mediated targeted gene
replacement and microarray-based genetic footprinting of random transposon libraries.
Methods to optimize synthetic operons for metabolic engineering applications are
described. Methods for introduction of genes and operons into the bacterial chromosome
are presented in a chapter on integration plasmid-based chromosomal expression of native
and foreign genes.
Strategies to assemble combinations of tagged integration plasmids, gene knockouts,
or knockout collections (e.g., Keio collection) are discussed in a chapter on high-through-
v

put double mutant assembly via conjugation. Protocols to assemble multiply modified
strains are provided in a chapter on P1 transduction.
In Section 2, analogous microbial engineering strategies for eukaryotic cells are pre-
sented, using the yeast S. cerevisiae as a model. This section also includes chapters describ-
ing creation and phenotypic trait selection with signature-tagged barcoded mutant
collections and libraries of mutant transcription factors; these methodologies have applica-
tion in a wide range of microorganisms.
In Section 3, examples of the proliferative adaptations of these base technologies to
strain engineer industrially important prokaryotic or eukaryotic microbial systems are pre-
sented. Introductory chapters on transformation and broad host range plasmid vectors
provide design guidance to develop robust methods for the critical first step of efficiently
introducing functional DNA into new microbes. This effort is guided by identification in
the annotated genome of genes whose products are detrimental to efficient transforma-
tion, for example, restriction endonucleases and secreted nonspecific nucleases. Targeted
elimination or neutralization of these genes improves broad host range plasmid transfor-
mation. In the case of fungi, nonhomologous recombination genes are also identified and
eliminated, to facilitate development of targeted homologous recombination-based methods.
This subsection then describes methods for applied strain engineering of microbial
organisms (prokaryotic and eukaryotic) with bioenergy potential for which sequenced and
annotated genomes are available. Once basic DNA transformation, replicating plasmids,
and homologous recombination-based chromosome integration methods in new organ-
isms are available, other techniques described in Sections 1 and 2 can be adapted. For
example, to facilitate application of the E. coli integration plasmid technology described in
Chapter 8, phage integration sites can be integrated into the genome at a permissive site
by homologous recombination, and the corresponding phage integrase supplied on a
broad host range plasmid.
Written for: Molecular and cellular biologists, molecular geneticists, bioengineers, and
microbiologists working in academia, pharmaceutical and biotechnology that perform
microbial strain engineering.
