The Blue-Green Algae
In situ studies on N2 fixation using the acetylene reduction technique.
TLDR
Data obtained in experiments designed to test the feasibility of employing a simple method for measuring acetylene reduction as an index of N2 fixation in the field illustrate that the method is practical and extremely sensitive.
Carbohydrate Accumulation and Osmotic Stress in Cyanobacteria
TLDR
While the trend was towards glucosylglycerol accumulation in marine strains and sucrose accumulation in freshwater forms, there were no absolute differences between cyanobacteria isolated from each habitat.
Osmotic adjustment and organic solute accumulation in unicellular cyanobacteria from freshwater and marine habitats
TLDR
The data suggest that (1) glycosylglycerol accumulation is not unique to marine cyanobacteria, and (2) the upper salinity limit for growth may be linked to organic solute accumulation, rather than habitat, with glucosyl Glycerol-accumulating isolates having a greater potential for growth in salt-stressed conditions than sucrose accumulators.
Thioredoxin as a Modulator of Glucose-6-phosphate Dehydrogenase in a N2-Fixing Cyanobacterium
Summary: Glucose-6-phosphate dehydrogenase (G6PDH) is a key enzyme involved in fixed carbon dissimilation in photosynthetic micro-organisms; in heterocystous cyanobacteria it may also be implicated
Multiphasic osmotic adjustment in a euryhaline cyanobacterium
TLDR
It is demonstrated that several inorganic and organic solutes are involved in osmotic adjustment in this cyanobacterium, with sequential changes in the relative importance of each solute following transfer to a saline medium.

TLDR
Information is provided on how to identify the Nitrogenase “building blocks” in bacteria, as well as the “complementary functions” of Nitrogenases and “inhibitors”.

TLDR
An attempt is made to evaluate the phytochemical properties of ammonia and its application in the context of nitROGENASE and its role in the regulation of NITROGenase.
Ecological studies on algal‐lysing bacteria in fresh waters
TLDR
Algal-iysing bacteria are present in five lochs, two reservoirs, one sewage works and five alkaline soils and it is probable that in most ecosystems the algae and the bacteria co-exist, although if the equilibrium changes markedly as a result of change in environmental conditions situations may arise where the bacteria may play an important role in the lysis of algal blooms.
