The observation that gas-vacuoles of blue-green algae do not disappear under vacuum has given rise to the belief that they are gas-tight structures. In this paper the following evidence is presented for the gas-vacuole membrane being freely permeable to gases. (1) In an attempt to identify the vacuole gas by mass spectrometry it was found that, after thorough evacuation, little or no gas could be obtained from the gas-vacuoles. (2) Using an ultrasonic method of destroying gas-vacuoles in…

Studies on the gas-vacuoles of blue-green algae

After consideration of a variety of different evidence it was concluded that the main function of gas-vacuoles is to lower the specific gravity of blue-green algal cells.


Spectrophotometric evidence is presented that the presence of inflated gas vacuoles in Nostoc muscorum does actually reduce the amount of light absorbed by the photosynthetic pigments, which shows that the gas vacUoles may indeed function as light shields.

GAS VACUOLES : Light Shielding in Blue-Green Algae

INTRODUCTION is attributable to the parietal distribution of the vacuoles within the cells of the particular strain of blue-green alga used in these experiments . Gas vacuoles are small, cylindrical,

Comparative Study of the Structure of Gas Vacuoles

The gas vacuole appears to be a homologous organelle in all of these procaryotic groups, and its presence in the gas vesicles of the green bacterium Pelodictyon clathratiforme was inferred from thin sections.

The biological significance of cell—water relations in gas-vacuolate organisms is discussed and the volumetric elastic modulus, e, which can be determined by measuring the turgor pressure of cells suspended in sucrose solutions of increasing concentration, is described.

The gas vesicles found in various planktonic prokaryotes are hollow, rigid structures permeable to gases. They collapse when the difference between the external hydrostatic pressure and internal gas

The properties and buoyancy-providing role of gas vacuoles in Trichodesmium Ehrenberg

All three species of the marine blue-green alga Trichodesmium collected in the Sargasso and Caribbean seas were found to possess gas vacuoles. The constituent gas vesicles were much stronger than

Permeability of gas vesicles to perfluorocyclobutane

It is concluded that C4F8 is able to permeate freely through the gas vesicle wall, if it permeates via pores, these must be at least as large as the gas molecules, which have a collision diameter of 0.63 nm.

The permeability of heterocysts to the gases nitrogen and oxygen

The observed permeability coefficient is low enough for the oxygen concentration in the heterocyst to be maintained close to zero by the probable rate of respiration, providing an anaerobic environment for nitrogenase.

The Interrelations of Cell Turgor Pressure, Gas-vacuolation, and Buoyancy in a Blue-green Alga

Experiments using 14C02 indicate that the increased rate of photosynthesis during the high light exposure is easily sufficient to account for the observed turgor rise, and can bring about collapse of sufficient of the alga's gas vacuoles to destroy its buoyancy.



Algal cultures and phytoplankton ecology

This book reviews the information gained from culture studies in the laboratory on the growth kinetics and metabolism of algae and considers to what extent this information is applicable to phytoplankton populations in nature.

Blue-Green Algae: Fine Structure of the Gas Vacuoles

The gas vacuoles seen in several species of blue-green algae under the light microscope are shown by electron microscopy to correspond to packed arrays of cylindrical, electron-transparent vesicles.
