TL;DR: It is reported here the widespread occurrence of a small, marine, chroococcalean cyanobacterium belonging to the genus Synechococcus.

TL;DR: The results support the view that nitrification is an important source of N(2)O in the environment and that nitrite-oxidizing bacteria (Nitrobacter sp.) and the dinoflagellate Exuviaella sp.

Abstract: The composition of the atmosphere is influenced both directly and indirectly by biological activity. Evidence is presented here to suggest that nitrification in soil is a potentially significant source of both NO and N2O. Between 0.3 and 10% of the ammonium oxidized by cultures of the soil bacterium Nitrosomonas europaea is converted to these gases. The global source for NO associated with nitrification could be as large as 15,000,000 tonnes N/yr, with a source for N2O of 5,000,000-10,000,000 tonnes N/yr. Nitric oxide has a key role in tropospheric chemistry, participating in a complex set of reactions regulating OH and O3. Nitrous oxide is a dominant source of stratospheric NO and has a significant influence on climate.

TL;DR: The effect of the initial substrate surface condition, as indicated by the critical surface tension for wetting, on the rate of attachment of marine bacteria to a variety of solid surfaces has been measured and their significance to the control of microbiological slime film formation is discussed.

TL;DR: A new chemolithotrophic nitrite-oxidizing bacterium, for which the name Nitrospira marina is proposed, was isolated from the Gulf of Maine.
