Abstract:
... BACKGROUND: Short chain oxylipins in plants as the main volatile organic carbon have been speculated to playing an important role for plant innate immunity, however, not yet intensively studied and far away established as the fully recognized algae defense signals. RESULTS: The production of 1-octen-3-ol is self-amplified via the fatty acid-oxylipin metabolic cycle through positive feedback loop. ...

Abstract:
... 3‐Bromopyruvate (3BP) is a small, highly reactive molecule formed by bromination of pyruvate. In the year 2000, the antitumor properties of 3BP were discovered. Studies using animal models proved its high efficacy for anticancer therapy with no apparent side effects. This was also found to be the case in a limited number of cancer patients treated with 3BP. Due to the “Warburg effect,” most tumor ...

Abstract:
... Algal blooms often occur in the tidal freshwater (TF) of the James River estuary, a tributary of the Chesapeake Bay. The timing of algal blooms correlates highly to a summer low-flow period when residence time is long and nutrients are available. Because of complex interactions between physical transport and algal dynamics, it is challenging to predict interannual variations of bloom correctly usi ...

A variety of β-glucans were identified as strong immune stimulator and exerted antitumor activities. Our previous work indicates that a β-1,3/1,6-glucan (BG136) derived from marina alga Durvillaea antarctica promotes the proinflammatory responses in macrophage cell line RAW264.7. In the present stud ...

With increasing concerns over the potential effect of NPs on aquatic organisms, investigations on NP toxicity to algae are rising. To date, the overall algal response to cope with NP toxicity is still uncertain. In this review, a meta-analysis was conducted to quantitatively as ...

Abstract:
... Estuaries are naturally dynamic ecosystems mixing fresh and marine waters, while consistently varying in depth and discharge due to diurnal tide shifts. Anthropogenic alterations impacting the Savannah River are expected to change the hydrology of the ecosystem and effect algal community structure and composition. The Savannah Harbor Expansion Project began recently with the aim of widening and de ...

Abstract:
... Algae play an important role in the internal nutrient cycling of shallow lakes and coves. Algae of shallow water bodies have been shown to thrive and even lead to eutrophic conditions despite a lack of measurable quantities of biologically available phosphorus (P) in the water during summer months. To study how sediment P release and algal growth are connected, water and sediment samples were coll ...

Abstract:
... An excessive increase in algae often has various undesirable effects on drinking water supply systems, thus proper management is necessary. Algal monitoring and classification is one of the fundamental steps in the management of algal blooms. Conventional microscopic methods have been most widely used for algal classification, but such approaches are time-consuming and labor-intensive. Thus, the d ...

Increased community diversity has been proposed as a strategy to increase productivity of algal cultures and reduce the risk of major pond collapses caused by grazing pests, which would enhance economics of wastewater-based mass algal cultivation. We tested whether higher algal diversity would increase biomass yield when grown in dairy wastewater, and whether polycultures would exceed the biomass ...
