The fatty acid composition of lipid extracts from cells of Bacillus acidocaldarius grown at temperatures of 50 to 70 C and pH values of 2 to 5 was determined by gas chromatography of the methyl esters. The most abundant fatty acids are 11-cyclohexylundecanoic and 13-cyclohexyltridecanoic, followed by anteiso- and iso-heptadecanoic; unsaturated acids are absent. Highly aerated cultures produce m...

The molecular interplay between cargo recognition and regulation of the activity of the kinesin-1 microtubule motor is not well understood. Using the lysosome adaptor SKIP (also known as PLEKHM2) as model cargo, we show that the kinesin heavy chains (KHCs), in addition to the kinesin light chains (KLCs), can recognize tryptophan-acidic-binding determinants on the cargo when presented in the con...

Juice spoilage caused by Alicyclobacillus acidoterrestris has troubled the global manufacturers for many years. Most approaches have failed to detect this bacterium with desirable sensitivity and selectivity because of their inherent drawbacks. In work, carbon dots (CDs) bright fluorescence were prepared which can be quenched HRP-catalyzed oxidation product p-phenylenediamine, via inner filter ...

Bacterial isolates assigned to the species Alicyclobacillus tolerans, which occupies an intermediate position between organotrophic genus and mixotrophic Sulfobacillus, were revealed as members of acidophilic chemolithotrophic community during stirred-tank bioleaching violarite–pentlandite–chalcopyrite concentrate at 40 °C. Surprisingly, this succeeded more common iron-oxidizing after a series ...

The germination behaviors of spores of Alicyclobacillus acidoterrestris, which has been considered to be a causative microorganism of flat sour type spoilage in acidic beverages, were investigated. The spores of A. acidoterrestris showed efficient germination and outgrowth after heat activation (80 degrees C, 20 min) in Potato dextrose medium (pH 4.0). Further, the spores treated with heat acti...
