Effects of biosurfactant produced by Lactobacillus casei on gtfB, gtfC, and ftf gene expression level in S. mutans by real-time RT-PCR

open access: yesAdvanced Biomedical Research, 2014
Background: The Streptococci are the pioneer strains in plaque formation and Streptococcus mutans are the main etiological agent of dental plaque and caries.

A quantitative image analysis pipeline for the characterization of filamentous fungal morphologies as a tool to uncover targets for morphology engineering: a case study using aplD in Aspergillus niger [PDF]

open access: yes, 2019
Background Fungal fermentation is used to produce a diverse repertoire of enzymes, chemicals, and drugs for various industries. During submerged cultivation, filamentous fungi form a range of macromorphologies, including dispersed mycelia, clumped ...

Novel biocatalysts for industrial fructooligosaccharides (FOS) production from fucosyltransferase and mutagenized invertase genes constitutively expressed in Komagataella phaffii (previously Pichia pastoris)

open access: yesCyTA - Journal of Food
Fructosyltransferases (FTFs) and invertases catalyze the production of short-chain fructo-oligosaccharides (FOS), levan, and inverted syrups from sucrose—compounds that are increasingly sought after in the global food industry.

Screening of microbial isolates for extracellular fructosyltransferase production

open access: yesAfrican Journal of Microbiology Research, 2015
Fructooligosaccharides are gaining importance by leaps and bounce every day due to their low caloric value and accompanying health benefits for the consumer. Hence, newer potential sources for the fructosyltransferase (Ftase) enzyme are thoroughly scrutinized.

Structure-function analysis of plant fructosyltransferases

open access: yes, 2005
Fructans are an important class of plant carbohydrates that consist of linear or branched chains of fructosyl moieties. Their synthesis requires fructosyltransferases (FTs) that catalyze the transfer of fructosyl units from a donor substrate (sucrose or fructan) to an acceptor substrate (sucrose or fructan).

Comparative analysis of fructosyltransferases of lactobacilli [PDF]

open access: yes, 2009
Some lactobacilli from food fermentations express fructosyltransferases, enzymes enabling them the production of fructans and fructooligosaccharides from sucrose. The work presents a comparison of known and newly identified Lactobacillus fructosyltransferases. Sequence comparison and molecular modelling approaches revealed a similar structure of all of

Physiological studies of Leuconostoc mesenteroides strain NRRL B-1149 during cultivation on glucose and fructose media [PDF]

open access: yes, 2012
Glycosyltransferases are extracellular and cell-associated sucrase enzymes produced mainly by lactic acid bacteria Leuconostoc mesenteroides, oral Streptococcus species and also Lactobacillus species.

Purification, cloning and functional characterization of a fructan 6-exohydrolase from wheat (Triticum aestivum L.) [PDF]

open access: yes, 2017
Fructans, β2-1 and/or β2-6 linked polymers of fructose, are produced by fructosyltransferases (FTs) from sucrose. They are important storage carbohydrates in many plants.
