As major contributors to global oxygen levels and producers of fatty acids, carotenoids, sterols, and phycocolloids, algae have significant ecological and commercial roles. Early algal models have contributed much to our understanding of circadian clocks at physiological and biochemical levels. The genetic and molecular approaches that identified clock

Algae encompass a phylogenetically diverse group; its members are placed in the domains Bacteria and Eukarya, in the latter dispersed in five supergroups. Contrary to common assumption, algae are found almost everywhere from aquatic to terrestrial habitats, some of them in symbiotic relationship, others thriving in harsh environments such as deserts ...

Eukaryotic algae are traditionally separated into three broad divisions: the rhodophytes, the chromophytes and the chlorophytes. The evolutionary relationships between these groups, their links with other eukaryotes and with other photosynthetic groups, such as euglenophytes and cryptophytes, have been the subject of much debate and speculation.

In the last few years, advances in algal research have identified the participation of haemoglobins in nitrogen metabolism and the management of reactive nitrogen and oxygen species. This chapter summarises the state of knowledge concerning algal haemoglobins with a focus on the most widely used model system, namely, Chlamydomonas reinhardtii. Genetic,

Algae and photosynthetic bacteria may be integrated or associated with Microbial Fuel Cells MFCs in a number of different ways including: (1) use of whole (intact) or lipid-extracted lyzed cells as the primary carbon-energy source for anodic microbial metabolism; (2) use of algal cultures (with light) as cathodic oxygenators to improve output. The idea

The green algae and the charophytes represent the most widely studied groups of algae in respect to their ploidy levels. In some genera increased size accompanies ploidy level changes as well as certain morphological modifications, but in other genera no evident obvious changes can be discerned.

In the following sections of this chapter we will try to give an outline of some algae characteristics and general information on their classification, distribution, structure, nutrition and reproduction. In the last paragraph a short account on the origin of eukaryotic algae is set out.

Combating planktonic algae with benthic algae
Ecological Engineering, 2015Anthropogenic eutrophication of surface waters may cause mass development of algae, including cyanoprokaryotes, with serious effects on ecosystem health. In the current study, drastic hydrological changes initiated a eutrophication process of a former backwater of the river Danube (Austria). As a first restoration measure, a gravel filter followed by a

Algae Crops: Coproduction of Algae Biofuels
2014The chapter discusses potential uses of algae, and the benefits of coproducing algae biofuels and value-added products such as wastewater treatment and fish. Because of the discussion and the data surrounding algae, and the large technical and economic barriers faced by producers of algae biofuels, we predict that the use of algae to produce energy ...
