“…5.0 to 7.0 mg cm −2 ). A fast increase in wet weight was also observed in 2007 (data not shown); contrary to this, in artificial systems (such as a reactor system) and on substrata (glass tubes, and glass and Teflon cylinders) longer periods (20 d-78 d) are required to obtain a stationary biofilm (26,34,35). The bare reed surface exposed to lake water just after the removal of the biofilm seems to be a competitive site for microbial attachment and growth; this may be related to the high activity of bacteria and the rapid increase in bacterial numbers, as discussed below.…”

The process by which a biofilm forms on the surface of the aquatic macrophyte Phragmites australis was investigated over a period of about two months (from mid-May to late-July, 2008) in Lake Biwa. The biofilm formed relatively quickly, its wet weight per unit area after seven day being that of a mature biofilm. This speed can be attributed to the many active bacteria in the early stage of its formation and the extracellular polymeric substances (EPS) they produce. The EPS carried electric charges that attracted nutrient ions from surrounding lake water, which, by electrostatic interaction, reached a high concentration as early as day 7 of the formation process. This significantly affected the biofilm community, which differed greatly from that of the lake water even at the beginning of biofilm formation. Brown amorphous compounds (a complex of organic and inorganic substances), covered the biofilm in the second half of its formation process producing a different community structure from that initially. This study revealed a fast and dynamic process of biofilm formation on the reed surface of reed.

“…Otherwise, rather similar biofilms were formed already after 4 weeks of growth, independently of the amount of phosphate in water, as evaluated from PLFA compositions. The biofilm formation has been rapid both on polyvinylchloride and steel surfaces exposed to the treated artificial groundwater (49) and on glass surfaces exposed to the treated groundwater (43). The second principal component also differentiated drinking water from warm water (Fig.…”

Microbial communities in biofilms grown for 4 and 11 weeks under the flow of drinking water supplemented with 0, 1, 2, and 5 g of phosphorus liter ؊1 and in drinking and warm waters were compared by using phospholipid fatty acids (PLFAs) and lipopolysaccharide 3-hydroxy fatty acids (LPS 3-OH-FAs). Phosphate increased the proportion of PLFAs 16:17c and 18:17c and affected LPS 3-OH-FAs after 11 weeks of growth, indicating an increase in gram-negative bacteria and changes in their community structure. Differences in community structures between biofilms and drinking and warm waters can be assumed from PLFAs and LPS 3-OH-FAs, concomitantly with adaptive changes in fatty acid chain length, cyclization, and unsaturation.

“…ATP has been rarely used to characterise biofilms on submerged wood surfaces, although Kooij et al (1995) showed that biofilm formation rates on surfaces can be obtained by ATP analysis as a function of time. Concentrations of ATP from epixylic biofilms reported in previous studies correspond well to our results Sinsabaugh et al, 1991;Spa¨nhoff et al, 2006).…”

-Colonization of incubated wood samples by invertebrates and biofilm was compared between a lowland and an upland stream over a 15 month period. Invertebrate densities increased during the first weeks of incubation and then decreased to rather stable densities during the remaining investigation period in both streams. Within the first incubation weeks invertebrate numbers were significantly higher in the lowland stream. Higher dissolved nutrient concentrations and water temperatures accelerated initial epixylic biofilm development in the lowland stream. Lowest invertebrate numbers on incubated branches in the lowland stream coincided with increased discharge. Extreme low flows in the upland stream resulted in lowest invertebrate numbers on incubated wood during the study. Temporal patterns of biofilm and invertebrates indicated some interactions, but statistical significance was low, which might be caused by the variety of interacting effects. Additionally, invertebrate assemblages of in-stream wood samples were collected from four lowland and four upland streams to examine differences of epixylic invertebrate assemblages between the two stream types. Invertebrate densities were significantly higher on submerged wood from lowland streams than wood from upland streams. However, no clear differences in invertebrate assemblages found between the stream types. The study results show that introduced wood in lowland and upland streams is rapidly colonized by aquatic invertebrates and provided an attachment site for biofilms. Invertebrate numbers during the first two months of incubation significantly overestimate the invertebrate numbers found on resident in-stream wood in lowland and upland streams. Analyses of taxonomic composition of wood-inhabiting invertebrate assemblages from natural wood from lowland and upland streams revealed that each stream displayed a rather specific epixylic fauna.
