The green microalga Dunaliella tertiolecta is attracted to ammonium and to several amino acids104 105 (Table 12.2). Calcium is required for full development of the response,104 and neither nitrate, urea, other amino acids, phosphate, vitamins, nor sugars elicit significant responses.105 Chemoattraction in a second species, D. salina, has been reported to several amino acids... 

Cytological investigation was focused on the effects of the RO fraction on the green microalga Ankistrodesmus braunii (at the dilution 1 20) and seeds of Raphanus sativus (at dilutions 1 8, 1 10, and 1 14).

Chlorella is a freshwater, unicellular green microalga that is widely used as a food supplement in Japan and around the world. Mass commercial cultivation of Chlorella for use as a health food supplement has taken place for over 35 years, with a more recent application in mariculture feed (Iwamoto, 2004). Many strains of Chlorella can be grown heterotrophically, allowing for production of a high-quality powder without contamination. Chlorella supplements are taken in the form of tablets, capsules, liquid, or as food additives. Claims for health benefits of Chlorella include improved immune function and improved control of hypertension, fibromyalgia, and ulcerative colitis (Halperin et al, 2003). 

In addition to transgenic advances in Chlorella sp. and C. reinhardtii, there has been great effort to develop the biotechnological tools required to research and exploit the commercially important green microalgae H. pluvialis and D. salina. These microalgae are the world s major suppliers of natural astaxanthin and p-carotene, respectively, and successful DNA... 

Microalgae have been used in various foods because of their ubiquitous availability in oceans and also due to their tremendous medicinal values. Earlier, as many as 206 strains of 152 marine microalgal species with UVA- and UVB-absorbing compounds were identified (Jeffrey et ah, 1999). Arthrospira platensis or Spirulina platensis (commonly called as nutraceutical spirulina) is a blue-green microalgae with a long history as a food source in East Africa and precolonial Mexico (Wikipedia).
