TLDR
A rapid method for distinction between gram-negative and grampositive bacteria by means of a 3% solution of potassium hydroxide is tested, with one exception only, a Bacillus macerans strain, which was definately gram- negative on staining.Abstract:
A rapid method for distinction between gram-negative and grampositive bacteria by means of a 3% solution of potassium hydroxide is tested on 71 gram-positive and 55 gram-negative bacterial strains. The method proved reliable with one exception only, a Bacillus macerans strain. That strain was definately gram-negative on staining. Other Bacillus strains were proved gram-positive by the test, even those being gram-negative on staining.read more

Phenotypic Characterization and the Principles of Comparative Systematics
TL;DR: The methods described in this chapter are based primarily on methods developed for the characterization and identification of organisms which have usually been isolated on nutrient-rich media.

Administration of different Lactobacillus strains in fermented oatmeal soup: in vivo colonization of human intestinal mucosa and effect on the indigenous flora.
TL;DR: The administration significantly increased the Lactobacillus counts on the jejunum mucosa, and high levels remained 11 days after administration was terminated, and a decrease in the number of members of the Enterobacteriaceae by 1,000-fold was observed on the rectal mucosa of two persons.

A highly purified enrichment culture couples the reductive dechlorination of tetrachloroethene to growth
TL;DR: H2 consumption was paralleled by chloride production, PCE degradation, cis-1,2-DCE formation, and growth of PER-K23, and Electron balances showed that all electrons derived from H2 or formate consumption were recovered in dechlorination products and biomass.

Detection of specific spoilage bacteria from fish stored at low (0°C) and high (20°C) temperatures
TL;DR: A specific count of fish spoilage organisms at both low and high temperatures could be obtained directly on an Iron Agar containing thiosulphate and cysteine where bacteria capable of forming H2S from either source of sulphur would appear as black colonies.

Dehalobacter restrictus gen. nov. and sp. nov., a strictly anaerobic bacterium that reductively dechlorinates tetra- and trichloroethene in an anaerobic respiration

TL;DR: It is proposed to affiliate the isolate to a new genus, Dehalobacter, with PER-K23 as the type strain of the new species De Halobacter restrictus, based on the cytological, physiological, and phylogenetic characterization of the isolate.

TL;DR: A manual for the identification of medical bacteria is presented for the first time in a systematic fashion.
BookDOI
Cowan and Steel's manual for the identification of medical bacteria
TL;DR: In this paper, a taxonomy of Gram-positive and Gram-negative bacteria is presented. But this taxonomy is not a complete taxonomy, and it does not cover all aspects of bacterial identification.

Cowan and Steel's manual for the identification of medical bacteria
TL;DR: This chapter discusses the development of approaches to bacterial systematics in theory and practice as well as the practical application of these approaches in the field of bacteriology.

Method for the distinction of gramnegative from grampositive bacteria
TL;DR: A test method is described for the distinction of gramnegative from grampositive bacteria, which can be detected by a colour reaction.
