The amino acid and monosaccharide content of the cell walls of Thiobacillus thiooxidans
… large quantities of Thiobacillus thiooxidans cells, (b) to find an acceptable method of rupturing the cells, (c) to find an acceptable method of isolating the cell walls, and (d) to analyze the cell wall components, especially the amino acid and sugar components. The strain of T. thiooxidans …

Glycerol from novel strains of halophytic microalgae
… accumulation and dissimilation in Dunaliella cells exposed to salinity stress under continuous light or dark regimes. (c) Maximize glycerol recovery from microalgal cultures using novel supercritical carbon dioxide (SC-CO2) extraction technology. Dunaliella and Asteromonas strains were shown …

Solution and solid-phase synthesis of potential carbohydrate vaccines for leishmaniasis and malaria
… 20 million people worldwide, and is caused by unicellular protozoan parasites. Cell surface carbohydrates are implicated in immune recognition of the parasite by host macrophages. The synthesis of a unique tetrasaccharide found on the parasite cell surface lipophosphoglycan is described. The …

Studies of the Biology, Pathogenicity and Control of the Lance Nematode, Hoplolaimus Galeatus, on Dent Corn, Zea Mays
… extensive mechanical damage, necrosis and cell rupture caused by migration and feeding in the cortex and feeding in the vascular cylinder. Eggs hatched 9-15 days after oviposition at 27 C and 13-19 days at 22 C in monoxenic culture. Second-stage juveniles developed to adults in 36 days in a …

The production, harvest and adsorptive recovery of an infectious herpes simplex virus vaccine
… involves culture of complementing Vero (CR2) cells, virus infection and manufacture, virus harvesting and subsequent downstream processing. The identification of suitable growth parameters for the complementing cell line and optimal limes for both infection and harvest are addressed. Various …

Anatomical Developments and the Role of Carbohydrate or Mineral Nutrient Deficiency in Bud Necrosis of 'Riesling' grapevines (Vitis Vinifera L.)
… a light microscope revealed a zone of compressed cells immediately beneath the primary bud axis within 60 days after budbreak. Cell rupture occurred in that zone within 90 days after budbreak. Scanning electron microscopy revealed a similar pattern of tissue destruction. Based on the hypothesis …

Investigating the mechanical properties of yeast cells
To predict cell breakage in bioprocessing it is essential to have an understanding of the cell wall mechanical properties. This project involved a study of the wall mechanical properties of individual Baker’s yeast cells (Saccharomyces cerevisiae) using compression testing by micromanipulation. An …

Mechanical algal disruption for efficient biodiesel extraction
… route to improving this is via disruption of the cells prior to lipid extraction, which can significantly increase energy recovery. Unfortunately, several obvious disruption techniques require more energy than can be gained. This dissertation examines the use of microbubbles to improve mechanical …

The release of nitrogen and carbohydrate from herbage during comminution
In forage-based livestock production systems, dietary N is often in excess supply. In addition, the efficiency with which ruminants utilise dietary N utilisation is low, leading to substantial losses of N to the environment, particularly in urine. There are considerable political and societal …
