Science, 1967
The article which Bond's committee objects to is an examination of the basic assumptions of the current spacecraft sterilization policy in the light of new knowledge of the planet Mars. It shows that the validity of these assumptions is, at the very least, questionable.

Preservation of Microorganisms
1978Publisher Summary This chapter discusses various methods used to preserve microorganisms. Storage in liquid nitrogen is one of the best methods for preserving all microorganisms. For some viruses, it may be better to freeze the sample rapidly, but slow freezing with a cryoprotective agent is desirable for all other organisms to retain maximum ...

A number of microorganisms can grow in grape must, depending on its composition: fermentable sugars with the bulk consisting of glucose and fructose; nitrogenous compounds, i.e. ammonia, amino acids and polypeptides; minerals with the bulk consisting of potassium, calcium, magnesium, phosphates and sulphates; growth factors, i.e ...

Applied Microbiology and Biotechnology, 2003
Sterols are vital components of all eukaryotic cells. This review describes the variety of sterol structures found in microalgae, yeasts, fungi, protozoans and microheterotrophs. Reports of the occurrence of sterols in prokaryotic cells are critically assessed.

The bacterial chromosome, while evolving by point mutations in its DNA, is thought to be rather stable with regard to its gross organization. For example, even though the DNAs of Salmonella and Escherichia cross-hybridize only weakly due to divergent sequence evolution (Demerec and New, 1965; Brenner et al., 1969), the genetic maps of the two bacteria ...

Thermal Inactivation of Microorganisms
Critical Reviews in Food Science and Nutrition, 2014This paper serves as an overview of various aspects of thermal processing. Heat processing of foods has a long history and is still one of the most important preservation methods. To guarantee microbiological safety and stability, large safety margins are often applied in traditional heat processes.

Annual Review of Microbiology, 1952
This review covers in part the literature appearing during 1951 , and is restricted primarily although not entirely to bacterial metabolism. As in previous years, the field of metabolism moved too rapidly for total coverage to be achieved in the space limitations imposed.
