Dynamic colour change as a signalling tool in bluelined goatfish (Upeneicthtys lineatus)

Ecology and Evolution, Volume 13, Issue 8, August 2023., 2023
Bluelined goatfish can dynamically change their body pattern and colour from a neutral white to a dark red banded pattern under 10 s. Goatfish are more likely to adopt a dark red banded pattern when actively feeding. Furthermore, associated fishes spend more time with goatfish displaying the red banding. It is likely bluelined goatfish use rapid colour

De novo 2′‐fucosyllactose bioproduction through modular engineering of a novel Escherichia coli K12‐derived strain

Food Bioengineering, Volume 2, Issue 2, Page 89-104, June 2023., 2023
A novel Escherichia coli K12 derivative was used as a chassis for 2′‐FL biosynthesis. Inactivation of transcriptional regulator McbR can improve 2′‐FL production. Double mutation F40S/Q237S of FutC‐J166 increased 2′‐FL titer by 1.55‐fold. Abstract The most abundant human milk oligosaccharide 2′‐fucosyllactose (2′‐FL) is a valuable component that has ...

Multi‐level metabolic engineering of Escherichia coli for high‐titer biosynthesis of 2′‐fucosyllactose and 3‐fucosyllactose

Microbial Biotechnology, Volume 15, Issue 12, Page 2970-2981, December 2022., 2022
An engineered Escherichia coli was developed for high‐titer FL biosynthesis by introducing multi‐level metabolic engineering strategies. Combined with the optimization of metabolic pathways and the performance improvement of rate‐limiting enzymes, 64.62 g/L of 2 '‐FL and 40.68 g/L of 3‐FL were finally obtained in the 3‐L bioreactors.

Metabolic engineering strategies of de novo pathway for enhancing 2′‐fucosyllactose synthesis in Escherichia coli

Microbial Biotechnology, Volume 15, Issue 5, Page 1561-1573, May 2022., 2022
A powerful Escherichia coli cell factory was developed to enhance 2′‐FL production. The systematic engineering strategies included modular combinatorial optimization, enhancement of NADPH and GTP supply, gene knockout and screening for α1,2‐fucosyltransferase. The final titre of 2′‐FL was 22.3 g l−1 by fed‐batch in a 3 l bioreactor.

[Retracted] Assessing Usability and Accessibility of Indian Tourism Websites for Visually Impaired

Journal of Sensors, Volume 2022, Issue 1, 2022., 2022
The tourism industry cannot ignore the needs of people with special needs. Providing accessible tourism is essential because of social and legal obligations, but also because they have large business opportunities. These people with special needs face challenges in every social, economic, and digital environment.

Multi‐enzyme Cascades for the In Vitro Synthesis of Guanosine Diphosphate L‐Fucose

ChemCatChem, Volume 13, Issue 8, Page 1981-1989, April 21, 2021., 2021
Multi‐enzyme cascade reactions: In vitro enzyme cascades for the one‐pot synthesis of guanosine diphosphate fucose (GDP‐Fuc) from low cost and readily available substrates. In situ co‐factor regeneration was implemented and a robust and scalable ion exchange chromatography protocol for the purification of GDP‐Fuc from the reaction was established.

Developing Hera-FFX for WCAG 2.0 [PDF]

, 2011
WCAG 2.0 was published in December 2008. It has many differences to WCAG 1.0 as to rationale, structure and content. Two years later there are still few tools supporting WCAG 2.0, and none of them fully mirrors the WCAG 2.0 approach organized around ...
