The objective of the present study was to investigate yeast communities in kefir grains and viili starters in Taiwan through conventional microbiological cultivation and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). The DNA sequencing was used as a validity technique to ensure that all isolates within each group belonged to just one species, and to confirm the id...

Production parallel systems are space-shared and hence employ batch queues in which the jobs submitted to the systems are made to wait before execution. Thus, jobs submitted to parallel batch systems incur queue waiting times in addition to the execution times. Prediction of these queue waiting times is important to provide overall estimates to the users and can also help metaschedulers make sc...

It is well established that non-Saccharomyces wine yeasts, considered in the past as undesired or spoilage yeasts, can enhance the analytical composition, and aroma profile of the wine. The contribution of non-Saccharomyces yeasts, including the ability to secret enzymes and produce secondary metabolites, glycerol and ethanol, release of mannoproteins or contributions to color stability, is spe...

The purpose of this paper is to introduce electrical discharge phenomena known as transient luminous events above thunderstorms to the lightning protection community. Transient luminous events include the upward electrical discharges from thunderstorms known as starters, jets, and gigantic jets, and electrical discharges initiated in the lower ionosphere such as sprites, halos, and elves. We gi...

This study identifies four types of wireless web services adopters (power users, entertainment users, information users and starters) based on a two-stage cluster analysis. The differences among the four groups were assessed based on gender, age and perceptions of wireless web services. No significant differences were found among the four groups in terms of gender, perceived ease of use and per...

Persons who develop schizophrenia are more likely than nondisordered persons to commit crimes. It is important to investigate those who offend, in order to develop treatment programs that effectively prevent recidivism, and eventually, early childhood violence prevention programs. Recent studies have shown that among offenders with major mental disorders, there are two groups: early starters, w...

Sourdough starter cultures are rich sources of endogenous lactic acid bacteria. The extended shelf lives of sourdough breads are attributed to a large array of organic acids and low-molecular-weight metabolites produced during the fermentation process. Different species belonging to the lactic acid bacteria group of microorganisms, mainly Lactobacillus and Leuconostoc, are increasingly gaining ...

Enturire is an alcoholic sorghum- and honey-based beverage traditionally produced by spontaneous fermentation. Its fermentation process is lengthy (5-7 days), does not guarantee product quality and safety and thus necessitates use of pure starter cultures. This study compared a modified production process of Enturire, with honey added at the start to the traditional one (honey added 3 days into...
