Excerpt: Aphanizomenon flos-aquae (pronounced, invisible living flower of the water) is the Latin name given to a wild-crafted species of cyanobacteria (blue-green algae) that is found in many places on Earth. Algae, in the collective sense, is sometimes called the basis of the entire food chain. The single-celled organism named Aphanizomenon flos-aquae (usually abbreviated AFA) is known to contain an array of digestible nutrients including essential fatty acids, active enzymes, vitamins, amino acids, minerals, proteins, complex sugars, and phytonutrients. Algae are classified by color: brown, gold, red, green, and blue-green. Color is determined by the photosynthetic pigments in each major division, and is responsible for each variety's capacity to absorb different wavelengths of light. Aphanizomenon flos-aquae (AFA) utilizes a broad light spectrum. Blue-green microalgae like AFA possess characteristics of both plants and bacteria. Like other plants and algae, AFA uses photosynthesis to produce the food material (glycogen) that is stored and utilized by the cell. While plants' cell walls are constructed of cellulose, AFA's cell walls are composed of peptidoglycan (carbohydrates and peptides), lipids (oils), polysaccharides (sugars), and proteins. Like bacteria, AFA is adaptable and can exchange genetic information, but chlorophyll is not found in most bacteria (bacteriochlorophyll pigment is used for photosynthesis by bacteria). Therefore, the distinctive designation cyanobacteria (Latin, c...
