Advances in genomic microbial taxonomy have opened the way to create a more universal and transparent concept of species but is still in a transitional stage towards becoming a defining robust criteria for describing new microbial species with minimum features obtained using both genome and classical polyphasic taxonomies. Here we performed advanced(More)
Five novel strains showing non-motile, alginolytic, halophilic and fermentative features were isolated from seawater samples off Okinawa in coral reef areas. These strains were characterized by an advanced polyphasic taxonomy including genome based taxonomy using multilocus sequence analysis (MLSA) and in silico DNA-DNA similarity (in silico DDH).(More)
The aim of this study is to review the current status of cancer chemoprevention and its effectiveness in treatment of oral premalignant lesions and prevention of their progression to oral cancer. The challenges encountered in the different oral cancer chemoprevention clinical trials, including lack of surrogate endpoints, reversal of histologic premalignant(More)
We investigated the cellular features and molecular phylogeny of Rhodella species and related unicellular red algae including undescribed species that we isolated. Results provide a new taxonomic interpretation at both generic and specific levels. The genus Rhodella is defined by its pyrenoid that is free from any internal structures. Based on phylogenetic(More)
