Physiological and biochemical responses of green microalgae from different habitats to osmotic and matric stress
Using 13C NMR spectroscopy and HPLC, it could be verified that ribitol functions as an osmotically regulated organic solute, the first proof of ribitol in free-living aeroterrestrial green algae.
Identification of the Smallest Structure Capable of Evoking Opsonophagocytic Antibodies against Streptococcus pneumoniae Type 14
The broader study described here, which evaluated 16 oligosaccharides, showed that the branched trisaccharide element Glc-(Gal-)GlcNAc is essential in inducing Pn14PS-specific antibodies and that the neighboring galactose unit at the nonreducing end contributes clearly to the immunogenicity of the epitope.
Stress metabolite pattern in the eulittoral red alga Pyropia plicata (Bangiales) in New Zealand – mycosporine-like amino acids and heterosides
Acclimation of the intertidal red alga Bangiopsis subsimplex (Stylonematophyceae) to salinity changes
A new unusual low molecular weight carbohydrate in the red algal genus Hypoglossum (Delesseriaceae, Ceramiales) and its possible function as an osmolyte
The data presented strongly support an osmotic function of digalactosylglycerol, a new low molecular weight carbohydrate detected in various species of the red algal genus Hypoglossum, which has never been reported for any other algal species before.
Biological soil crusts of temperate forests: Their role in P cycling
Synthesis of compounds with antiproliferative activity as analogues of prenylated natural products existing in Brazilian propolis.
