Pioneering the works of Brookman (1975), Middelberg et al. (1992a, 1992b) and Kleinig and Middelberg (1996), on cell disruption of yeast through HPH (high pressure homogenizer), the underlying factors in improving energy yield from biomass source has to be considered. This has become a global...

This study investigated the use of Breadfruit Starch Hydrolysate (BFSH) as the sole carbon source for bioethanol production and the optimization of the fermentation parameters. The results showed that the yeast was able to utilize the BFSH with and without nutrient supplements, with highest...

Microbial lipids have the potential to substantially reduce the use of liquid fossil fuels, though one obstacle is the energy costs associated with the extraction and subsequent conversion into a biofuel. Here we report a one-step method to produce FAME (fatty acid methyl esters) from...

A thin-shell silk cocoon (TSC), a residual from the silk industry, is used as a support material for the immobilization of Saccharomyces cerevisiae M30 in ethanol fermentation because of its properties such as high mechanical strength, light weight, biocompatibility and high surface area. In...

Global transposable characteristics in the complete DNA sequence of the Saccharomyces cevevisiae yeast is determined by using the metric representation and recurrence plot methods. On the basis of the correlation distance of nucleotide strings, 16 chromosome sequences of the yeast, which are...

Achieving consistency of growth pattern for commercial yeast fermentation over batches through addition of water, molasses and other chemicals is often very complex in nature due to its bio-chemical reactions in operation. Regression models in statistical methods play a very important role in...

Andreas Wagner <p> <p> The transcription of many eukaryotic genes is regulated via cooperative interactions among transcription factors (TFs). Cooperativity may be homotypic, involving binding of only one transcription factor to multiple sites in a genes' regulatory region. It may also be heterotypic,...</p></p>

Acid hydrolysis of surplus cellulosic materials, such as bagasse, into fermentation sugars offers enormous opportunity world wide to add incremental value to farming operations and displace expensive, imported, polluting oil fuel products. Arkenol has developed and patented a strong acid...
