In vivo functional analysis of L-rhamnose metabolic pathway in Aspergillus niger: a tool to identify the potential inducer of RhaR [PDF]

BMC Microbiology, 2017
Background The genes of the non-phosphorylative L-rhamnose catabolic pathway have been identified for several yeast species. In Schefferomyces stipitis, all L-rhamnose pathway genes are organized in a cluster, which is conserved in Aspergillus niger ...

New l-Rhamnose-Binding Lectin from the Bivalve Glycymeris yessoensis: Purification, Partial Structural Characterization and Antibacterial Activity [PDF]

Marine Drugs, 2023
In this study, a new l-rhamnose-binding lectin (GYL-R) from the hemolymph of bivalve Glycymeris yessoensis was purified using affinity and ion-exchange chromatography and functionally characterized. Lectin antimicrobial activity was examined in different

Engineering a filamentous fungus for L-rhamnose extraction. [PDF]

AMB Express, 2016
L-Rhamnose is a high value rare sugar that is used as such or after chemical conversions. It is enriched in several biomass fractions such as the pectic polysaccharides rhamnogalacturonan I and II and in naringin, hesperidin, rutin, quercitrin and ulvan. We engineered the filamentous fungus Aspergillus niger to not consume L-rhamnose, while it is still

Investigation on L-rhamnose metabolism of Loigolactobacillus coryniformis subsp. coryniformis DSM 20001 and its propionate-containing fermentates [PDF]

Applied and Environmental Microbiology
Propionate is an important short-chain carboxylic acid (SCCA) that serves as an effective antimicrobial agent for food preservation. Previous research has highlighted that few Lactobacillaceae can synthesize propionate by metabolizing deoxyhexoses via ...

Evaluation of Ulva lactuca hydrolysates as a feedstock for clostridial fermentations to produce 1,2-propanediol [PDF]

Frontiers in Microbiology
Macroalgae are an abundant and underutilized renewable feedstock that can be exploited for the production of various low- and high-value biomolecules. The study herein describes a mild acid and base process to hydrolyze the green macroalgae Ulva lactuca ...

The Loss-of-Function Mutation aldA67 Leads to Enhanced α-L-Rhamnosidase Production by Aspergillus nidulans

Journal of Fungi, 2022
In Aspergillus nidulans L-rhamnose is catabolised to pyruvate and L-lactaldehyde, and the latter ultimately to L-lactate, via the non-phosphorylated pathway (LRA) encoded by the genes lraA-D, and aldA that encodes a broad substrate range aldehyde ...

Glycosides and Oligosaccharides in the L-Rhamnose Series

Agricultural and Biological Chemistry, 1967
In order to investigate the substrate-specificity of α-l-rhamnosidase induced in Aspergillus species, the titled compounds were synthesized employing the various kinds of methods.One is the Helferich reaction by using the sirupy l-rhamnose teteraacetate and appropriate phenols in the presence of p-toluenesulphonic acid or zinc chloride etc.

Metabolism of L-Rhamnose in Arthrobacter pyridinolis [PDF]

Journal of General Microbiology, 1976
In Arthrobacter pyridinolis, a respiration-coupled transport system for L-rhamnose caused accumulation of free L-rhamnose, while a phosphoenolpyruvate: L-rhamnose phosphotransferase system caused accumulation of L-rhamnose I-phosphate (Levinson & Krulwich, 1974).
