Tropical bloom-forming mesoalgae Cladophoropsis sp. and Laurencia sp.-responses to ammonium enrichment and a simulated heatwave.

Algal blooms are increasing worldwide, driven by elevated nutrient inputs. However, it is still unknown how tropical benthic algae will respond to heatwaves, which are expected to be more frequent under global warming. In the present study, a multifactorial experiment was carried out to investigate the potential synergistic effects of increased ammonium inputs (25 μM, control at 2.

Sustainable blue economy: Opportunities and challenges.

The term 'blue economy', first introduced in 2010, is the sustainable use of ocean resources for economic growth, jobs, ocean health, and to improve livelihoods. However, a sustainable blue economy faces various challenges in the form of global warming, ocean acidification, and lack of knowledge about the ocean; for example, 95% of the sea is still unexplored, making it more important to understand the blue economy and implement it on a global scale. Other challenges include harmful algal blooms (HABs), invasive species, coral bleaching, and thermohaline circulation.

First report of Planomicrobium okeanokoites associated with Himantothallus grandifolius (Desmarestiales, Phaeophyta) from Southern Hemisphere.

Gram-positive, aerobic, motile, rod-shaped, mesophilic epiphytic bacterium Planomicrobium okeanokoites was isolated from the surface of endemic species Himantothallus grandifolius in Larsemann Hills, Eastern Antarctica. The diversity of epiphytic bacterial communities living on marine algae remains primarily unexplored; virtually no reports from Antarctic seaweeds. The present study used morpho-molecular approaches for the macroalgae and epiphytic bacterium characterization.

Concise review of green algal genus Thuret.

(Ulotrichales, Chlorophyta) is the most intensively cultivated genus among green seaweeds, accounting for over 90% of total green algal cultivation. It is commonly found in the eulittoral zones of marine and estuarine habitats, thus contributing significantly to the ecology of the coastal ecosystem. Morphologically, the frond of is blade-like with eponymous one-cell thickness; therefore, it is also known as "Slender sea lettuce".

A Review on Microbial Products and Their Perspective Application as Antimicrobial Agents.

Microorganisms including actinomycetes, archaea, bacteria, fungi, yeast, and microalgae are an auspicious source of vital bioactive compounds. In this review, the existing research regarding antimicrobial molecules from microorganisms is summarized. The potential antimicrobial compounds from actinomycetes, particularly spp.
