If nutrients concentrations arereduced in the water column, the algae will suffer.

Red Algae's Superior Photosynthesis - Astrobiology …

Algal metabolism concerns the biochemical and transport processes by which algae take up nutrients and convert them into the materials needed for growth, reproduction and defence of the organisms. Many of the metabolic processes that occur in algae are common to those found in other living organisms. This commonality is described, but emphasis is given to those major metabolic processes in algae that are unique to, or differ in detail from, those of other organisms. This includes mechanisms of light harvesting, carbon acquisition and aspects of nitrogen (N) and sulfur (S) assimilation as well as formation of unique secondary metabolites. In addition the consequences of growth in extreme environments, such as nutrient limitation and exposure to extremes of visible and UV light, for algal metabolism are considered. The exploitation of algal metabolism and its products in biotechnology is also briefly described.

First, the aquarist can attempt to avoid introducing red algae into anuncontaminated aquarium.

Red Algae (Rhodophyta) and Red Seaweed Species Profile

Algae can exist as single cells, an example of which is Chlamydomonas, or joined together in chains like Spirogyra or made up of many cells, for instance Rhodymenia (red seaweed).

I also like to obtain them when they first arrive at the aquarium shopbefore they have a chance to pick up any new algae or have their rootsdamaged from an additional planting.


In bright light the rate of photosynthesis in your algae should be ..

General arrangement of antenna complexes in algae. In green algae as well as in higher plants (a) the antenna complex is in the membrane and associates with the photosystem in the membrane. In red algae and cyanobacteria (b) the antenna complex is a phycobilisome and is a soluble protein. The phycobilisome attaches to the photosystem where the photosystem extends from the membrane.

Chloroplast Evolution in Red and Blue Algae | …

The intensively cultivated agricultural plants average about 3% in photosynthetic efficiency, and most crops range from 1-4%. This is also typical of algae.

Corraline red algae build up calcium ..

dynamic shows that there are about 10,000 species of seaweeds, of which about 6,500 are red algae (), the vast majority of which are marine. These are found in the intertidal and in the subtidal to depths of up to 40, or occasionally, 250 m. The main biomass of red algae worldwide is provided by the Corallinaceae and Gigartinaceae.

Photoacclimation in three species of freshwater red algae

The red algae and are now the most important sources of , a commonly used ingredient in food, particuarly yoghurts, chocolate milk and repared puddings. , , and other red algae are used in the manufacture of the all-important , used widely as a growth medium for microorganisms, and for food and biotechnological applications.

Photoacclimation in three species of freshwater red algae

A very important group of red algae is the coralline algae, which secrete calcium carbonate onto the surface of their cells. Some of these corallines are articulated (right, Corallina, with flexible erect branches; others are crustose (below). These have been used in bone-replacement therapies. Coralline algae were used in ancient times as vermifuges, thus the binomial Corallina officinalis.
