Attachment of bacteria. At low ionic strength of the medium — as in many freshwaters — bacteria-surface interactions are controlled by the effects of van der Waals attraction and electrostatic repulsion. At high ionic strength — as in seawater — steric interactions between the outer cell surface macromolecules and the substratum gain in importance (van Loosdrecht et al., 1989 Rijnaarts etal., 1999). Additionally, flagellar and twitching motility of bacteria was found to be essential in the process of attachment by bacteria onto surfaces (Pratt and Kolter, 1998 O Toole and Kolter, 1998). It seems that extracellular polysaccharides of bacteria are not involved in the adhesion process itself. However, bacterial extracellular polysaccharides are necessary for the development of a biofilm and for the formation of microcolonies (Allison and Sutherland, 1987 Hoyle et al., 1993).

The principal PUFA of interest is EPA which has been found in a number of marine and freshwater bacteria Altermonas, Shewanella, Flexibacter and Vibrio (Ring0 et aL, 1992 Akimoto et aL, 1990, 1991 Yazawa et aL, 1992). Yazawa et aL (1992) have described the possible commercial production of EPA using a novel isolate, SCRC-2738, described as resembling Shewanella putrefaciens, and which was isolated after a survey of 24000 bacteria from fish and marine mammals.

The New Zealand freshwater limpet Latia neritoides (Fig. 6.1.1) is the only known example of a freshwater luminous organism, with two possible exceptions certain species of luminous bacteria and the larvae of certain species of fireflies. The limpet inhabits shallow clear streams in the North Island of New Zealand, clinging to stones and rocks. Latia has a small oval-shaped shell (6-8 mm long), and secretes a luminous mucus that emits a greenish glow around the body only when disturbed the limpet does not show a spontaneous luminescence. The luminescence of Latia was first reported by Suter (1890) and further details including a positive luciferin-luciferase reaction were described by Bowden (1950). Both the luciferin and the luciferase have... 

Increased amounts of faecal-oral water-borne pathogens (virus, bacteria and protozoa) and microbial indicators (bacterial and viral) have been reported in groundwater bodies [18], karst springs [19, 20], surface freshwater [21-26], marine waters used for bathing [27-29] and shellfish growing [30] as well as tap water [31]. 

The freshwater cyanophyte Aphanazomenon flos-aquae (see Chapter 6, by Carmichael), long suspected to contain saxitoxin-like compounds, has been shown to contain saxitoxin and neosaxitoxin, and has been an important tool in the elucidation of saxitoxin biosynthesis (49,50 see Chapter 2, by Shimizu). This research clearly demonstrates that the saxitoxins can be produced by a procaryote thus, the suggestion that bacteria may produce the saxitoxins becomes more plausible.

Molecular hydrogen is an important intermediate in the degradation of organic matter by microorganisms in anoxic habitats such as freshwater and marine sediments, wet land soils, and the gastrointestinal tract of animals. In these particular conditions H2 is produced during fermentation of carbohydrates, lipids, nucleic acids, and proteins by anaerobic bacteria and,...
