The utilization of bacilli as larvicidal agents against anopheline and culicine mosquitoes in Turkey. I. Larvicidal activity of Bacillus thuringiensis serotype H-14.

Standard IPS-82 and a wettable powder (Bactimos) of Bacillus thuringiensis (H-14) were tested against local mosquito species, Cx. pipiens and An. sacharovi, in the laboratory in Turkey. The dose-mortality regression lines for both organisms had similar slopes with each formulation. Bactimos was less effective against both organisms, especially at higher concentrations (LC95/LC50 5.78 vs 1.95).

[Microbial production of glucose/fructose syrups]. / Glukoz/fruktoz suruplarinin mikrobiyal üretimi.

With the ever-increasing demand for sugar and the trend in rising price, rapid progress in research on new and/or alternative sweeteners has been inevitable during the past decade or so. Pure glucose, glucose/fructose, glucose/maltose syrups are often called "isosyrups". Isosyrups have been recognized as a good alternative sources of sugar. These are used today in the manufacture of soft drinks, jams and jellies, confectionary, baking fermentation, dietetic and infant food, ice-cream, pharmaceutical processes, etc. Isosyrups are produced by hydrolysis of starch and cellulocis raw materials have been utilized for the production of isosyrups.

The use of step enzymes as markers during meiosis and ascospore formation in Saccharomyces cerevisiae.

The activities of ornithine aminotransferase, sucrase and acid and alkaline phosphatases have been studied throughout sporulation in Saccharomyces cerevisiae. The same enzymes were monitored during synchronous vegetative growth. Each of these enzymes has been demonstrated to increase in a 'step' manner during both growth and sporulation. Alkaline phosphatase increased in a two-step manner whereas the others increased in a single step. The times of increase of these enzymes formed a similar sequence during both sporulation and growth. It has been proposed that these enzymes are under a common mechanism of control during growth and sporulation and that the sequence of enzyme appearance may be used as markers of the sporulation process.
