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 ...

Algae, which live in marine or freshwater, are photosynthetic organisms. They vary greatly in size, morphology, and degree of complexity of their body structures. Algae are generally divided into two main groups, microalgae, which are small in size, and macroalgae, which are larger in size.
