In a previous paper (Hare, Wildy, Billett, and Twort, 1952) a scheme employing fermentation of carbohydrates and organic acids was put forward for the classification into six groups of the anaerobic cocci derived from human beings. There is at present extremely little information as to the occurrence of anaerobic cocci on the mucous and skin surfaces of normal human beings. This, together with ...

The fermentation process in which organic material is degraded and biogas (composed of mainly methane and carbon dioxide) is produced, is referred to as anaerobic digestion. Anaerobic digestion processes occur in many places where organic material is available and redox potential is low (zero oxygen). This is typically the case in stomachs of ruminants, in marshes, sediments of lakes and ditche...

In the stagnant loop syndrome an abnormal anaerobic flora colonizes the small bowel. Anaerobic organisms are characterized by fermentation reactions leading to the production of volatile fatty acids. This paper describes the measurement of intrajejunal volatile fatty acid concentrations in 11 patients with the stagnant loop syndrome. Nine normal persons and 18 patients with gastrointestinal dis...

This study aimed to characterize and evaluate an inedible giant water lily as a bioenergy feedstock. The conversion of organics can produce renewable energy. Composition indicated that is excellent feedstock for bioethanol biogas production. Fermentation effluent wastes from anaerobic digestion were transformed directly into ethanol using alkali pretreatment. Under mild operating conditions, al...

Mannitol fermentation has long been considered an important test in studying staphylococci, and yet reports on its correlation with other tests vary widely. Hallman (Proc. Soc. Exptl. Biol. Med., 36, 789) found a 91 per cent correlation with the coagulase test on 487 strains. On the other hand, Plastridge et al. (Storrs Agr. Expt. Sta., Bull. 231) found that 74 per cent of their 211 coagulasene...

distilled water. The medium was prepared by placing 40 to 50 sterile rice grains in each sterile petri dish containing 25 ml of sterile distilled water. After hydration the rice grains became submerged beneath a thin layer of water, which discouraged the growth of molds. Twenty samples of soil from various sources were tested by this method. The results of a few of these are shown in table 1. S...
