Algal culture is the culturing of algae in ponds or other resources. Maximum productivity occurs when the "exchange rate" (time to exchange one volume of liquid) is equal to the "doubling time" (in mass or volume) of the algae. PBRs can hold the culture in suspension, or they can provide a substrate on which the culture can form a biofilm ...
These blooms are recognizable by large blades of algae that may wash up onto the shoreline. [14] Once the nutrient is present in the water, the algae begin to grow at a much faster rate than usual. In a mini bloom, this fast growth benefits the whole ecosystem by providing food and nutrients for other organisms. [10]
Picochlorum is a genus of green algae in the class Trebouxiophyceae. [1] [3] As of February 2022, AlgaeBase regarded the name as illegitimate. [1] It is a native marine microalga fit for cultivation at high growth rates, showing a 2-hour multiplying time in ideal conditions. [4]
The brown algae include the largest and fastest growing of seaweeds. [6] Fronds of Macrocystis may grow as much as 50 cm (20 in) per day, and the stipes can grow 6 cm (2.4 in) in a single day. [13] Growth in most brown algae occurs at the tips of structures as a result of divisions in a single apical cell or in a row of such
According to page 30 on Aquatic Species Program report, [9] the A-strain of Botryococcus braunii did not function well as a feedstock for lipid-based fuel production due to its slow growth (one doubling every 72 hours). However, subsequent research by Qin showed that the doubling time could be reduced to 48 hours in its optimal growth ...
Algal bloom commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest . Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution ), entering the ...
A type of algae, Ancylonema nordenskioeldii, was found in Greenland in areas known as the 'Dark Zone', which caused an increase in the rate of melting ice sheet. [89] The same algae was found in the Italian Alps, after pink ice appeared on parts of the Presena glacier. [90] The various sorts of algae play significant roles in aquatic ecology.
Maerl (also rhodolith) is a collective name for non-geniculate coralline red algae with a certain growth habit. [1] Maerl grows at a rate of c. 1 mm per year. [2] It accumulates as unattached particles and forms extensive beds in suitable sublittoral sites. [3] The term maerl originally refers to the branched growth form of Lemoine (1910) [4 ...
