A Simple, Rapid, and Cost-Effective Method for Assessing Carbohydrate Partitioning in Microalgae and .

Carbohydrates serve crucial functions in most living cells, encompassing structural and metabolic roles. Within the realms of plant and algal biology, carbohydrate biosynthesis and partitioning play pivotal roles in growth, development, stress physiology, and various practical applications. These applications span diverse fields, including the food and feed industry, bioenergetics (biofuels), and environmental management.

Competitive fitness and stability of ammonium-excreting Azotobacter vinelandii strains in the soil.

Non-symbiotic N-fixation would greatly increase the versatility of N-biofertilizers for sustainable agriculture. Genetic modification of diazotrophic bacteria has successfully enhanced NH release. In this study, we compared the competitive fitness of A.

Bioprospecting for fungal enzymes for applications in microalgal biomass biorefineries.

Microalgal biomass is a promising feedstock for biofuels, feed/food, and biomaterials. However, while production and commercialization of single-product commodities are still not economically viable, obtaining multiple products in a biomass biorefinery faces several techno-economic challenges. The aim of this study was to identify a suitable source of hydrolytic enzymes for algal biomass saccharification.

Climate-Simulated culturing suggests high microalgal biomass and oil productivities in most of the South American continent.

Background: Current production costs of microalgal biomass indicate that only highly-productive cultivation facilities will approach commercial feasibility. Geographical site selection for siting those facilities is critical for achieving target productivities. The aim of this study was to provide a semi-empirical estimation of microalgal biomass and lipids productivity in South America.

Deferred control of ammonium cross-feeding in a N-fixing bacterium-microalga artificial consortium.

There is an increasing interest in the use of N-fixing bacteria for the sustainable biofertilization of crops. Genetically-optimized bacteria for ammonium release have an improved biofertilization capacity. Some of these strains also cross-feed ammonium into microalgae raising additional concerns on their sustainable use in agriculture due to the potential risk of producing a higher and longer-lasting eutrophication problem than synthetic N-fertilizers.
