Increases in alginate production and transcription levels of alginate lyase (alyA1) by control of the oxygen transfer rate in Azotobacter vinelandii cultures under diazotrophic conditions

Ponce, Belén; Urtuvia, Viviana; Maturana, Nataly; Peña, Carlos; Díaz-Barrera, Álvaro.
Electron. j. biotechnol; 52 (), 2021
BACKGROUND: Alginates are polysaccharides used in a wide range of industrial applications, with their functional properties depending on their molecular weight. In this study, alginate production and the expression of genes involved in polymerization and depolymerization in batch cultures of Azotobacter ...

Alginate overproduction and biofilm formation by psychrotolerant Pseudomonas mandelii depend on temperature in Antarctic marine sediments

Vásquez-Ponce, Felipe; Higuera-Llantén, Sebastián; Pavlov, María Soledad; Ramírez-Orellana, Ramón; Marshall, Sergio H; Olivares-Pacheco, Jorge.
Electron. j. biotechnol; 28 (), 2017
Background: In recent years, Antarctica has become a key source of biotechnological resources. Native microorganisms have developed a wide range of survival strategies to adapt to the harsh Antarctic environment, including the formation of biofilms. Alginate is the principal component of the exopolysacch...

Volatile metabolites produced from agro-industrial wastes by Na-alginate entrapped Kluyveromyces marxianus

Güneşer, Onur; Karagül-Yüceer, Yonca; Wilkowska, Agnieszka; Kregiel, Dorota.
Braz. j. microbiol; 47 (4), 2016
Abstract The aim of this study was to evaluate the effects of alginate entrapment on fermentation metabolites of Kluyveromyces marxianus grown in agrowastes that served as the liquid culture media. K. marxianus cells entrapped in Na-alginate were prepared using the traditional liquid-droplet-forming meth...
