Alginates are abundant linear polysaccharides produced by brown algae and some bacteria. They have multiple biological roles and important medical and commercial uses. Alginates are comprised of D-mannuronic acid (M) and L-guluronic acid (G) and the ratios and distribution patterns of M and G profoundly impact their physiological and rheological properties.

Bacteria can be applied as biofertilizers to improve crop growth in phosphorus (P)-limited conditions. However, their mode of action in a soil environment is still elusive. We used the strain ALC_02 as a case study to elucidate how Bacillus subtilis affects dwarf tomato cultivated in soil-filled rhizoboxes over time.

Article Synopsis
  • Lactic acid bacteria (LAB) are utilized to improve the shelf life and quality of fermented milk, and this study explores their potential in enhancing textures in plant-based fermentations, specifically using Lactococcus lactis strains.
  • The research found that many LAB strains that improved texture in fermented milk also did so in fermented soybean, highlighting their versatility despite the differences in components between the two substrates.
  • The study suggests that exocellular polysaccharide production plays a crucial role in texture enhancement, leading to the identification of 10 strains with novel polysaccharide biosynthesis gene clusters, though their specific functions in different matrices remain unclear.

Effectors are small, secreted proteins that promote pathogen virulence. Although key to microbial infections, unlocking the intrinsic function of effectors remains a challenge. We have previously shown that members of the fungal Avr4 effector family use a carbohydrate-binding module of family 14 (CBM14) to bind chitin in fungal cell walls and protect them from host chitinases during infection.

Polysaccharides from plant biomass are the most abundant renewable chemicals on Earth and can potentially be converted to a wide variety of useful glycoconjugates. Potential applications of glycoconjugates include therapeutics and drug delivery, vaccine development and as fine chemicals. While anomeric hydroxyl groups of carbohydrates are amenable to a variety of useful chemical modifications, selective cross-coupling to non-reducing ends has remained challenging.
