Summary: A pioneering study using the HPLC-CHEMTAX analytical approach was conducted to investigate the dynamics of phytoplankton functional groups (PFGs) in the Ashtamudi estuary and its adjacent nearshore waters. The study found that the estuary exhibited high temperature, salinity, and ammonium levels during the non-monsoon seasons, while the summer monsoon resulted in low salinity and increased nitrate and phosphate concentrations. Cyanobacteria were the dominant phytoplankton community during the non-monsoon season, while diatoms dominated the nearshore waters. The study also revealed that the estuary was phosphorus-limited for phytoplankton growth during the non-monsoon seasons.

Summary: The green microalga Chlamydomonas reinhardtii is a promising cell biofactory for producing secreted recombinant proteins. However, purifying these proteins from the extracellular space of the mutant strain UVM4 has proven challenging due to the proteins being trapped in cell wall protein aggregates. Through analysis and comparison with the ancestor strain 137c, we discovered that the high molecular weight extracellular protein aggregates in UVM4 are predominantly composed of a specific class of cell wall glycoproteins called pherophorins. These findings provide insights into the extracellular space of strain UVM4 and offer potential strategies to enhance purification of secreted proteins and increase yields of recombinant biopharmaceuticals.

Summary: Poly-hydroxy-butyrate (PHB) bioplastic resin can be produced from atmospheric CO2 using cyanobacteria. Random mutagenesis combined with FACS was used to select mutants with higher lipid content, resulting in two strains with significantly increased PHB yields, biomass accumulation, and volumetric PHB density. The highest PHB yielding strain was 43% higher than the wild type, and the highest volumetric PHB density was 75% higher. This study shows the potential of random chemical mutagenesis and FACS in increasing PHB productivity in cyanobacteria, making bioplastic production economically viable.

Summary: Mesoscale eddies play a significant role in driving variability in phytoplankton functional trait composition and primary productivity relative to adjacent waters. In the offshore waters of southeast Australia, these eddies provide an important enrichment mechanism in nitrogen-limited areas, but there is limited knowledge about primary productivity within cold and warm-core eddies and the factors that affect phytoplankton communities in this variable environment. This study quantified net primary productivity and compared phytoplankton species composition in five different environments, highlighting the importance of cold-core eddies in regulating primary productivity in eastern Australian waters and the need to incorporate phytoplankton size structure in eddy-resolving models for accurate forecasts.

Summary: The Vistula Lagoon, one of the two lagoons on the Polish coast, is economically and environmentally significant. This study aims to calculate the water balance of the lagoon before and after the construction of a canal through the Vistula Spit. The construction of the new connection may impact the lagoon's water balance and its biotic and abiotic environment. Data on precipitation, evaporation, inflow from the catchment, and inflow/outflow through the Strait of Baltiysk were collected for mathematical modeling. The study suggests that the construction of the new canal will not significantly alter the lagoon's water balance but may cause environmental problems.

Summary: We demonstrate that wind-driven Ekman transport enhances the advection and mixing of cells, leading to the transport of colder water from the Surface Antarctic Waters to the warmer waters of the northern Polar Front belt. This mechanism provides cells with a favorable temperature environment, allowing for specific species and community growth rates to develop blooms under non-light limiting macronutrients and iron conditions. Our findings have important implications for increased productivity in a future warming climate.
