Recent advances in synthetic biology have resulted biological technologies with the potential to reshape way we understand and treat human disease. Educating students about ethics underpinning these is critical empower them make informed future policy decisions regarding their use inspire next generation of biologists. However, hands-on, educational activities that convey emerging topics can be difficult implement due expensive equipment expertise required grow living cells. We present...

Training the future synthetic biology workforce requires opportunity for students to be exposed biotechnology concepts and activities in secondary education. Detecting Wolbachia bacteria arthropods using polymerase chain reaction (PCR) has become a common way investigate apply recombinant DNA technology science classroom. Despite this important activity, cutting-edge biotechnologies such as clustered regularly interspaced short palindromic repeat (CRISPR)-based diagnostics have yet widely...

As the field of synthetic biology expands, need to grow and train science, technology, engineering, math (STEM) practitioners is essential. However, lack access hands-on demonstrations has led inequalities opportunity practice. In addition, there a gap in providing content that enables students make their own bioengineered systems. To address these challenges, we develop four shelf-stable cell-free biosensing educational modules work by simply adding water DNA freeze-dried crude extracts...

Cell-free systems derived from crude cell extracts have developed into tools for gene expression, with applications in prototyping, biosensing, and protein production. Key to the development of these is optimization extract preparation methods. However, applied nature optimizations often limits investigation complex themselves, which contain thousands proteins reaction networks hundreds metabolites. Here, we sought uncover black box metabolites Escherichia coli cell-free reactions based on...

ABSTRACT Spatial organization of pathway enzymes has emerged as a promising tool to address several challenges in metabolic engineering, such flux imbalances and off-target product formation. Bacterial microcompartments (MCPs) are spatial strategy used natively by many bacteria encapsulate pathways that produce toxic, volatile intermediates. Several recent studies have focused on engineering MCPs heterologous interest, but how this affects MCP assembly function is poorly understood. In...

RNA-guided nucleases from CRISPR-Cas systems expand opportunities for precise, targeted genome modification. Endogenous in many prokaryotes are attractive to circumvent expression, functionality, and unintended activity hurdles posed by heterologous effectors. However, each system recognizes a unique set of protospacer adjacent motifs (PAMs), which requires identification extensive screening randomized DNA libraries. This challenge hinders development endogenous systems, especially those...

ABSTRACT Gas fermentation by autotrophic bacteria, such as clostridia, offers a sustainable path to numerous bioproducts from range of local, highly abundant, waste and low-cost feedstocks, industrial flue gases or syngas generated biomass municipal waste. Unfortunately, designing engineering clostridia remains laborious slow. The ability prototype individual genetic parts, gene expression, biosynthetic pathway performance in vitro before implementing them cells could help address these...
