Electrochemical Proton Gradient across the Membranes of Photophosphorylating Bacteria
The goal of this review is to consider recent experimental data concerning a new parameter of prokaryotic membranes—the electrochemical protons gradient (ΔμH+) predicted by Mitchell (1966)—in the case of photopho... - Chapter
Some aspects of water filtering activity of filter-feeders
On the basis of the previous publications, our new data and the existing scientific literature, we have formulated some fundamental principles that characterize the pivotal roles of the biodiversity of filterf... - Chapter and Conference Paper
Suspension-Feeders as Factors Influencing Water Quality in Aquatic Ecosystems
Suspension-feeders are found in both pelagic and benthic systems. They function as an important part of an ecosystem's biomachinery that maintains water quality in aquatic systems. They remove suspended matter... - Chapter
Studying effects of some surfactants and detergents on filter-feeding bivalves
Effects of several surfactants and chemical mixtures on marine bivalves were studied. An anionic surfactant, sodium dodecylsulphate (SDS), and a cationic surfactant, tetradecyltrimethylammonium bromide (TDTMA)...

Problems at the Ontogenetic Level
Next to the molecular and genetic level of the organization of living matter is the ontogenetic one. At this ontogenetic level individual organisms are considered as the units of life.

Use of Natural Purification of Water Cycle and Water Management as a solution towards Ecodesign
One of the major problems now affecting the world is Water Pollution. Natural forms of pollution have been always presented in water systems, Except for exceptional cases, the natural purification processes is... - Chapter
Problems at the Species-Population Level
A population is a basic elementary unit at the species-population level. In the sense of evolution genetics, as population is designated a minimum self-propagating group of single-species individual animals wh...

Need for Ecologization of Society’s Activities
In the 20th century, industrial production, commodity consumption and other development indices are going up the exponential curve. Neither the Earth’s biosphere, nor economy, nor man as a biological species w... - Chapter

Reconstitution of Membrane Transport Functions
At the very outset of this survey of membrane transport reconstitution, it is fitting to remind the reader that reconstitution is not a technique, nor is it new. Rather it is a basic approach to biological sci...

Fate and Effects of the Surfactant Sodium Dodecyl Sulfate
Surface-active agents, or surfactants, are detersive chemicals characterized by having two different moieties, one polar and the other nonpolar, at opposite ends of a single molecule. The polar moiety is refer...

Pump and Displacement Currents of Reconstituted ATP Synthase on Black Lipid Membranes
Purified ATP synthase (F0F1) from Rhodospirillum rubrum was reconstituted into asolectine liposomes which were then adsorbed to a planar lipid bilayer. After the addition of an inactive photolabile ATP derivative... - Chapter
Proton Translocation by Bacteriorhodopsin in Model Systems
Bacteriorhodopsin is a rhodopsin-like pigment found in the cell membrane of halobacteria. It occurs in discrete patches with a planar hexagonal lattice structure known as the purple membrane (Oesterhelt and St...
Isoprenoids and Bacteriorhodopsin in Halobacteria
Halophilic (salt-loving), thermophilic, acidophilic or psychrophilic organisms are all examples of biological adaption to ex- treme environmental conditions. Halophilic organisms are distinguished from marine ...

Electrical Double Layers in Pigment-Containing Biomembranes
Displacement photocurrents are unique to pigment-containing biomembranes. They belong to a special class of bioelectric signals that are generated by rapid charge displacements in the membranes. Interpretation... - Chapter
Model Photoresponsive Membranes
Basic mechanisms underlying action of light on biological systems are located in the membranous portions of cells. In plant photosynthesis the conversion of solar to chemical energy is associated with thylakoi...
Chapter
Reconstitution of Biological Membranes
Biological membranes are currently envisaged as a fluid lipid bilayer with the membrane proteins freely floating in it (Singer and Nicolson, 1972). Most of these proteins are involved in membrane-linked functi...

Electrical Currents of the Light Driven Pump Bacteriorhodopsin. The Role of Asp 85 and Asp 96 on Proton Translocation
The functional properties of the light-driven proton pump of bacteriorhodopsin and two point-mutated analogues have been studied on planar lipid membranes and on gels where membrane fragments containing the io...

Internal Electric Fields Generated by Surface Charges and Induced by Visible Light in Bacteriorhodopsin Membranes
Bacteriorhodopsin functions as a light-driven proton pump, and is the major protein component in the purple membrane of Halobacterium halobium. An externally applied electric field has a prominent effect on its p...
