Abstract:
A novel actinobacterium, designated LHW52908T, was isolated from a marine sponge, Leucettachagosensis, collected in the South China Sea. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain LHW52908T was member of the family Geodermatophilaceae, with highest similarities to Geodermatophilus obscurus DSM 43160T (97.7 %), Geodermatophilus siccatus CF6T (97.6 %) and Geodermatophiluschilensis B12T (97.5 %). Multilocus sequence analysis confirmed that the strain should be a member of genus Geodermatophilus. Chemotaxonomic characteristics confirmed the genus-level affiliation of strain LHW52908T. Based on phylogenetic data, average nucleotide identity and digital DNA-DNA hybridization results, strain LHW52908T could be distinguished from its closest neighbours, representing a novel species of the genus Geodermatophilus, for which the name Geodermatophilusmarinus sp. nov. is proposed, with the type strain LHW52908T (=DSM 106570T=CCTCC AA 2018014T).

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...
