Enhancement of fructosyltransferase and fructooligosaccharides production by A. oryzae DIA-MF in Solid-State Fermentation using aguamiel as culture medium [PDF]

, 2016
The aim of this work was to improve the production of fructosyltransferase (FTase) by Solid-State Fermentation (SSF) using aguamiel (agave sap) as culture medium and Aspergillus oryzae DIA-MF as producer strain.

Enhancing the Heterologous Fructosyltransferase Activity of Kluyveromyces lactis: Developing a Scaled-Up Process and Abolishing Invertase by CRISPR/Cas9 Genome Editing

Frontiers in Bioengineering and Biotechnology, 2020
The enzymatic production of prebiotic fructo-oligosaccharides (FOS) from sucrose involves fructosyltransferases (FFTs) and invertases, both of which catalyze forward (transferase) and reverse (hydrolysis) reactions.

Laminaria digitata Extract Improved Leaf Meristem Protection Under Drought and Nitrogen Uptake After Rehydration Through Hormesis-Based Chemical Priming in Lolium perenne. [PDF]

Plant Cell Environ
ABSTRACT Drought is among the most damaging stress for plants, impacting crop yield and grassland sustainability. This study aimed to evaluate the biostimulant effect of an algal extract from Laminaria digitata on Lolium perenne cultivated in a growth chamber. Leaves were sprayed at different concentrations 7 days before stopping irrigation.

Biotechnological production and application of fructooligosaccharides [PDF]

, 2016
Currently, prebiotics are all carbohydrates of relatively short chain length. An important group is the fructooligosaccharides, which are a special kind of prebiotics associated to their selective stimulation of the activity of certain groups of colonic ...

In vitro digestibility and fermentability of fructo-oligosaccharides produced by Aspergillus ibericus [PDF]

, 2018
The bifidogenic potential of fructo-oligosaccharides (FOS) produced by a newly isolated strain Aspergillus ibericus was studied. Their activity was compared to FOS produced by Aureobasidium pullulans and to a non-microbial commercial FOS sample ...

The fructosyltransferase of Streptococcus salivarius [PDF]

New Phytologist, 1993
SUMMARYThe nature of the fructans produced by oral streptococci and the β‐D‐fructosyltransferases (FTFs) that synthesize them from sucrose are considered in this review. Models for the apparent unique surface expression and secretion of the FTF produced by Streptococcus salivarius are discussed in light of recent evidence obtained from the cloning and ...

Fructooligosaccharide production by Penicillium expansum [PDF]

, 2010
Fructooligosaccharides (FOS) production by Penicillium expansum was evaluated. In a first stage, the best conditions for P. expansum growth and sporulation were established with potato/dextrose/ agar being the most suitable medium at between 22 and ...

Inactivation of cell-associated fructosyltransferase in Streptococcus salivarius [PDF]

Journal of Bacteriology, 1981
In stationary phase, 95% of the fructosyltransferase (FTase) activity of Streptococcus salivarius ATCC 25975 was found associated with the cells. Within the first 15 min after inoculation into fresh medium, the specific activity of cell-associated FTase decreased by 92% of its initial value. After this period of initial loss, the enzyme was synthesized

Maximization of fructooligosaccharides and β-fructofuranosidase production by Aspergillus japonicus under solid-state fermentation conditions [PDF]

, 2012
The conditions of temperature, moisture content, and inoculum rate able to maximize the production of fructooligosaccharides (FOS) and β-fructofuranosidase (FFase) enzyme by solid-state fermentation were established.

Regulation of Sucrose-Sucrose-Fructosyltransferase in Barley Leaves [PDF]

Plant Physiology, 1991
The activity of sucrose-sucrose-fructosyltransferase (SST), a vacuolar enzyme strongly induced by light in excised leaves of barley (Hordeum vulgare L.), rapidly declined even in continuous light upon feeding of cycloheximide (CHI). The rate of decline was similar to that observed in light-treated leaves that were placed into darkness, in the presence ...
