Control of Fungal Morphology in Continuous Culture
… project was the development of a system for the continuous production of fungal spores by the control of mycelial morphology and the optimisation of environmental factors stimulating sporulation. Spores, considered a dormant stage in the life cycle of fungi, have been shown to contain enzymes …

The physiology of industrial yeast in continuous culture
The physiology of industrial yeasts in continuous culture: F. R. Wardrop <br/><br/>The growth and physiology of <i>Saccharomyces cerevisiae</i> GB4918 (baker’s yeast) was studied under glucose-limitation in chemostat culture. Levels of lg/1 (0.1% w /v) glucose allowed cell growth while preventing …

A reassessment of the production of acetone and butanol by Clostridium acetobutylicum in continuous culture
… Clostridium acetobutylicum P 262 was studied in continuous culture under conditions where the nutrients were present in excess of the requirements and the cell growth was limited by the products formed during the fermentation. This system differs from most continuous culture systems used to …

Effects of iso-alpha-acids on rumen fermentation and comparison of microbial populations between rumens and continuous culture fermenters
Two experiments were conducted using dual-flow continuous culture fermenters to study rumen fermentation in vitro. The first experiment examined the effects of iso-alpha-acids from Humulus lupulus (Hops) extract on rumen fermentation. Iso-alpha-acid extract (IE) was provided to continuous culture …

The effects of solution conditions on the kinetics of microbial ferrous-iron oxidation by Leptospirillum ferriphilum in continuous culture
The objective of this work was to investigate the effects of a wide range of solution conditions,namely: temperature, pH, dissolved Al and Mg, and the effect of total iron concentration on the kinetics of microbial ferrous-iron oxidation by Leptospirillum ferriphilum, with a view to developing a …

Population oscillations in continuous culture of the prey-predator systems Escherichia coli - Dictyostelium discoideum and Proteus vulgaris - Dictyostelium discoideum
… of expected population oscillations in a continuous flow culture of prey-predator interactions was made. A Coulter Counter was used to enumerate the population levels and periodic checks were performed with a Petroff-Hausser bacterial counts. Population oscillations of both prey and …

Evaluation of the Redostat™ device for the study of ferrous iron biological oxidation kinetics.
… biological oxidation kinetics, namely batch and continuous culture techniques. However, the continuously changing conditions in batch culture and the slowness and bacterial wash out in continuous culture are significant weaknesses for these experimental methods. This work has evaluated the …

Biofilm Formation by Moraxella Catarrhalis
… catarrhalis. Growth of M. catarrhalis in a continuous-culture biofilm system resulted in little detectable change in outer membrane protein production compared to broth-grown M. catarrhalis. Biofilm-grown M. catarrhalis may produce an extracellular polysaccharide and different colony …

The Effects of Starvation on The Ruminal Bacteria Megasphaera Elsdenii and Selenomonas Ruminantium
… nutrient starvation after growth in batch and/or continuous culture. Both organisms exhibited a very limited survival capacity in comparison to other bacteria reported in the literature. This capacity appears to have been at least partially influenced by pre-starvation growth conditions and levels …

Mixotrophic Production of Omega-3 Fatty Acid-rich Alga Phaeodactylum tricornutum on Biodiesel-derived Crude Glycerol
… using crude glycerol in batch mode mixotrophic culture of P. tricornutum was investigated. Once the mixotrophic culture was established, parameters involved in increasing the biomass and EPA production were optimized. These included nitrogen source, level of supplemental carbon dioxide, and …

Biological treatment and recycling of textile processing effluents
In the present work, a mixed culture of Pseudomonas spp. capable of decolourising a range of selected textile dyes was isolated and used to develop a continuous culture system for the treatment of textile dye effluents. The bioprocess was optimised using biomass growth supports. The presence of a …

Improving fiber by-product utilization in high concentrate diets
… increasing WSC inclusion rates were compared in continuous culture fermenters and fiber digestibility was reduced as starch inclusion increased with an optimum balance between DM and fiber digestibility between 80 and 90% SH inclusion. A subsequent feedlot study determined maximum WSC inclusion …
