The exact nature and function of the metachromatic (volutin) granules seen in many microorganisms is still a matter of conjecture although polymetaphosphates (polymers of highenergy anhydride-linked phosphates) are a known constituent. The object of this paper is to re-examine volutin as a cytological entity, and to present a working hypothesis on the mechanism of formation of this substance. T...

We present the full genome sequence of Clostridium sp. strain BNL1100, a Gram-positive, endospore-forming, lignocellulolytic bacterium isolated from a corn stover enrichment culture. The 4,613,747-bp genome of strain BNL1100 contains 4,025 putative protein-coding genes, of which 103 are glycoside hydrolases, the highest detected number in cluster III clostridia.

A stud) of the availability of the vitamins and amino acids esser ial for Lactobacillu8 plantarum in cucumber fermentations (Costilow and Fabian, 1953b) indicated that the concentrations of some of these nutrients were influenced by the microflora present. Therefore, a survey was made of two species of bacteria and four yeast species that have been found to be most active in cucumber fermentati...

September 2006 | Volume 4 | Issue 9 | e299 One of the organizing principles of life on Earth is that cells cooperate. This is evident in the case of multicellular organisms, from nematodes to humans, but it also appears to apply widely among single-celled organisms such as bacteria, fungi, and amoeba. In many cases, the label “single-celled” applies to only part of the life cycle of these organ...
