Pseudomonas adhesion

In ethanol In the absence of tin exhibits an emission maximum at 555 nm upon 366 nm excitation. Figures 3 and 4 show emission spectra of the Sn /flavonol complex on Irregularly shaped glass beads of 10-100 tm diameter, and of BuSn /flavonol accvmulated by Pseudomonas 244 cells respectively. The glass bead study serves as a model of tin adhesion to a small heterogeneous surface from which spectra can be directly obtained only by mlcrospectrofluorometrlc techniques.

The carbohydrate binding of H. pylori is still a complex situation with many postulated receptors. The picture is further confounded by the use of different strains, phase-variation, and use of different methods. The complex carbohydrate recognition pattern identified might partly be a result of the intense research efforts directed towards H. pylori. A parallel case is the multiple adhesive mechanisms described for Pseudomonas aeruginosa, another bacterium subjected to intense studies [65, and references therein].

Physiochemical conditions at the solid surface-liquid interface are not identical to those in the bulk phase, i.e. the environment at the interface therefore will be different in terms of the concentrations of ions, small molecules or polymers. The chemical species concerned may be beneficial to the cells or toxic [Mozes and Rouxhet 1992]. Unlike natural surfaces such as rocks and stones the surfaces found in heat exchangers are usually metallic and may give rise to ions that are generally not present in natural aqueous systems. Vieira et al [1993] report that metallic ions such as and seem to interfere with the initial adhesion and development of biofilms formed from Pseudomonas fluorescens, whereas no such effect was observed with aluminium ions.

Specific studies of the use of gum biopolymers directly in plant disease management are very few. Most of the time these gums are used as carriers for biocontrol formulations of Trichoderma spp. Pseudomonas and Bacillus spp. These gums are also used as adhesive for various seed treatment chemicals. A few examples where gum biopolymers were used for plant disease management are given in Table 16.3. 

In a further study of Pseudomonas NCMB 2021, Fletcher and Loeb (34) compared attachment to a variety of low energy surfaces. Their clata, together with data from Zisman (2. 35). Metsik (36) and Mittal (13) is plotted in Figure 4. This curve is very sTmi-lar to curves relating c or Wg to adhesive strength for plastics (Dyckerhoff and Sell, ) and metals (Kitazaki and Hata, 1J[) The...

Plant and other lectins have the ability to adhere strongly to microbial cell surfaces and lectins are responsible for the adhesion of Rhizobim trifotii to root hair cells of clover. Discovery of lectins which will bind other microbes may lead to the use of lectins as bridging agents to bind cells to inert support materials. Fletcher (83) studied the effects of proteins on the adhesion of a marine Pseudomonas sp. to polystyrene Petri dishes. Bovine serum albumin, gelatin, fibrinogen and pepsin (pKj — 5.8) all inhibit attachment at pH 7.6 when present either prior to or concurrently with the microbial cells. Bovine serum albumin decreased the adhesion of previously attached cells.
