Abstract:
A Gram-stain-positive, aerobic, endospore-forming bacterium isolated from a coolant lubricant was studied for its taxonomic allocation. On the basis of 16S rRNA gene sequences, strain KSS164-79T shared highest similarity (92.3-92.4 %) to type strains of the species Marinicrinis sediminis,Paenibacillus dongdonensis, Paenibacillus abyssi and Paenibacillus motobuensis. In phylogenetic trees based on the 16S rRNA gene, strain KSS164-79T always formed a distinct cluster with the type strain of M. sediminis. The fatty acid profile supported the grouping of the strain to the genus Marinicrinis. As major fatty acids, anteiso-C15 : 0, iso-C15 : 0 and iso-C16 : 0 were detected. The polar lipid profile contained the major components diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and two unidentified glycolipids. The major quinone was menaquinone MK-7. In addition, physiological and biochemical test results allowed the clear phenotypic differentiation of strain KSS164-79T from M. sediminis. Hence, KSS164-79T represents a novel species of the genus Marinicrinis, for which the name Marinicrinis lubricantis sp. nov. is proposed, with KSS164-79T (=DSM 104943T=LMG 30062T=CCM 8749T=CIP 111345T) as the type strain.

To calculate the required thickness of the lubricant layer, the tangential velocity at the shaft's surface must first be determined. This velocity is calculated by converting the rotational speed to angular velocity...

Cyclic Processes And Isolated Systems
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state.
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...
