Ribosome pausing in amylase producing Bacillus subtilis during long fermentation.

Microb Cell Fact

January 2025

Swammerdam Institute for Life Sciences, University of Amsterdam, Science Park 904, Amsterdam, 1098 XH, The Netherlands.

Background: Ribosome pausing slows down translation and can affect protein synthesis. Improving translation efficiency can therefore be of commercial value. In this study, we investigated whether ribosome pausing occurs during production of the α-amylase AmyM by the industrial production organism Bacillus subtilis under repeated batch fermentation conditions.

The in-vitro digestibility of instant noodles: Interplay of texture, microstructure and starch structure.

Food Res Int

February 2025

Tianjin Key Laboratory of Food Science and Health, School of Medicine, NanKai University, Tianjin 300071, China. Electronic address:

Instant noodles are a worldwide food staple. However, the correlation between its production methods and nutritional characteristics remains unclear. This study aims to elucidate the effects of hydrothermal (steaming and boiling) and cooling techniques on instant noodles in-vitro digestibility.

Investigating the hydrolysis of complex carbohydrates with salivary α-amylase.

Food Res Int

February 2025

Department of Food Science, University of Copenhagen, Rolighedsvej 26, 1958 Frederiksberg C, Denmark. Electronic address:

Currently, little is known about how complex carbohydrates (maltodextrins) with varying degrees of polymerisation (DP) and molecular branching interact with α-amylase in human saliva and the associated amounts and structures of generated reducing sugars. Therefore, this study aimed to investigate salivary α-amylase and the subsequent reducing sugars generated with complex carbohydrate stimuli. A secondary aim was to investigate reducing sugar generation and complex carbohydrate taste sensitivity.

The expression system has been developed into a chassis for the production of heterologous lipases, attributed to its strong capabilities in protein production and secretion, robust post-translational modifications, and favourable safety profile. However, the system's relatively low expression levels remain a challenge, hindering its ability to meet the increasing demands of large-scale production. Strain C19, screened by high-throughput methods combining droplet microfluidics and flow cytometry, was demonstrated to be a potential chassis cell based on fermentation kinetic analysis and transcriptome sequencing.
