Studies of aquatic micro-organisms in domestic swimming pools
Microbial attachment and proliferation on a surface leads to the formation of a structure known as a biofllm. In this thesis attention is directed towards the attachment of microorganisms to submerged surfaces in private swimming pools Samples were taken from two private swimming pools located in …

Collective dynamics in flowing suspensions of swimming micro-organisms
Micro-organisms first appeared on earth about 3.8 billion years ago and can be found almost everywhere now. In terms of number and biomass, they in fact constitute the majority of terrestrial life and despite their tiny size play a vital role in a wide variety of phenomena. Although there has been …

Some effects of ultrahigh frequency induced electrical currents on certain micro-organisms
High frequency induced electrical energy has been used by medical science for several years to produce heat internally in the human body. The uses of such a process are many and varied. They range all the way from producing artificial fever in the entire body to heating one certain afflicted spot …

Fermentation of uniformly labeled C14 glucose in vitro by micro-organisms of the bovine rumen
The present report describes a procedure developed for tracing C¹⁴ labeled glucose in rumen material in vitro. Twenty-five ml. samples of rumen fluid were incubated with uniformly labeled glucose for 1 1/2 hours in a closed system. The distribution of activity in both unfermented control samples …

Structural studies of the capsular polysaccharides from some strains of Klebsiella and Cryptococcus neoformans micro-organisms
The structures of the exopolysaccharides from a number of strafos of the bacterial genus KlebsieUa have been investigated and compared. ·All of these polysaccharides have been shown to be composed of regularly repeated oligosaccharide units containing -glucuronic acid and three to five hexose …

Interactions between nematodes, potato and soil-borne micro-organisms and their effect on the management of potato cyst nematodes
… assays showed that PCN hatch was influenced by microorganisms present in the ridge, but not in the bulk soil. Community level physiological profiling (CLPP) of ridge and bulk soil, using BIOLOG EcoplatesTM, demonstrated differences in bacterial functional diversity between the two soil types. An …
