Biomarker assessment of spatial and temporal changes in the composition of flocculent material (floc) in the subtropical wetland of the Florida Coastal Everglades (FCE) from May 2007 to December 2009
Flocculent material (floc) is an important energy source in wetlands. In the Florida Everglades, floc is present in both freshwater marshes and coastal environments and plays a key role in food webs and nutrient cycling. However, not much is known about its environmental dynamics, in particular its biological sources and bio-reactivity. We analysed floc samples collected from different environments in the Florida Everglades and applied biomarkers and pigment chemotaxonomy to identify spatial and seasonal differences in organic matter sources. An attempt was made to link floc composition with algal and plant productivity. Spatial differences were observed between freshwater marsh and estuarine floc. Freshwater floc receives organic matter inputs from local periphyton mats, as indicated by microbial biomarkers and chlorophyll-a estimates. At the estuarine sites, the floc is dominated by mangrove as well as diatom inputs from the marine end-member. The hydroperiod (duration and depth of inundation) at the freshwater sites influences floc organic matter preservation, where the floc at the short-hydroperiod site is more oxidised likely due to periodic dry-down conditions. Seasonal differences in floc composition were not consistent and the few that were observed are likely linked to the primary productivity of the dominant biomass (periphyton in the freshwater marshes and mangroves in the estuarine zone). Molecular evidence for hydrological transport of floc material from the freshwater marshes to the coastal fringe was also observed. With the on-going restoration of the Florida Everglades, it is important to gain a better understanding of the biogeochemical dynamics of floc, including its sources, transformations and reactivity.
Modeling Flocculation Processes of Cohesive Sediment Through Moment Methodology
<p>The data were used in the paper "Modeling Flocculation Processes of Cohesive Sediment Through Moment Methodology" which was submitted to "<em>Water Resources Research</em>". In this paper, a new mechanistic Lagrangian-type flocculation dynamic model was proposed by solving the population balance equation with moment methodology and similarity transformation, and the influence of particles' surface heterogeneities (<em>F</em><sub>2a</sub>) was incorporated. Furthermore, the roles of shear rate, sediment concentration, particle size and surface heterogeneity were investigated theoretically.</p>

Molecular mechanism of flocculation self-recognition in yeast and its role in mating and survival
Saccharomyces cerevisiae flocculation occurs when fermentable sugars are limiting and is therefore considered as a way to enhance the survival chance of Flo-expressing yeast cells. In this paper the role of Flo1p in mating was demonstrated by showing that the mating efficiency which contributes to the increased survival rate as well by generating genetic variability is increased when cells flocculate. This was revealed by liquid growth experiments in a low shear environment and differential transcriptome analysis of FLO1 expressing cells compared to the non-flocculent wild-type cells. The results show that a floc provides a uniquely organized multicellular ultrastructure that provides a suitable microenvironment to induce and perform cell conjugation. S. cerevisiae strains BY4742 WT BY4742::FLO8 and BY4742 [FLO1] were grown in microgravity and 1-g. A transcriptomic analysis was performed and the transcriptome data were integrated with the high quality protein-protein interaction networks. The identified high score sub-networks (qvalue < 0.001) were considered and further evaluated concerning their GO enrichment using a hypogeometric test. The data were from the Ying B-1 experiment.
