SEMIA 690(T) is a nitrogen-fixing symbiont of Centrosema pubescens, and comprises the recently described species Bradyrhizobium viridifuturi. Its draft genome indicates that it belongs to the Bradyrhizobium elkanii superclade. SEMIA 690(T) carries two copies of the regulatory nodD gene, and the nod and nif operons resemble those of Bradyrhizobium diazoefficiens.

A systematic study was conducted on Phyllostachys pubescens by analyzing the chemical constituents of its rhizome and culm at different ages. Our results indicated that the ash contents of the rhizome and culm of P. pubescens at different ages showed the largest coefficient of variation (CV), followed by alcohol benzene extractives. The CVs of acidinsoluble lignin, holocellulose, HNO3-C2H5OH ce...

Trametes is a cosmopolitan genus of white rot polypores, including the "turkey tail" fungus, T. versicolor. Although Trametes is one of the most familiar genera of polypores, its species-level taxonomy is unsettled. The ITS region is the most commonly used molecular marker for species delimitation in fungi, but it has been shown to have a low molecular variation in Trametes resulting in poorly ...

The decolouration of the metal-complex dyes Bemaplex Navy M-T (150 mg/L) and Bezaktiv Blue BA (150 mg/L) in nine successive batches by immobilised cultures of the white-rot fungus Trametes pubescens was studied. Two different types of immobilisation supports were used: the commercial carriers Kaldnes™ K1 (synthetic supports) and sunflower-seed shells (SS) (natural supports). Bemaplex showed mor...

Thirty years after selective timber harvest in the Kibale National Park, Uganda, many abandoned logging gaps are dominated by Acanthus pubescens, and show little forest recovery. To examine if this arrested successional state was caused by limited tree seedling growth and survival, we planted seedlings of four forest tree species (Albizia grandibracteata, Mimusops bagshawei, Prunus africana and...

Eight strains of Trichoderma species (T. strigosum, T. erinaceus, T. pubescens, T. stromaticum, and T. spirale as well as T. cf. strigosum, T. cf. pubescens) were selected because of their antagonistic potential against Eutypa dieback and Esca which are fungal diseases of grapevine trunks. These isolates were screened for the production of a group of polypeptide antibiotics named peptaibiotics,...

Sequences of the internal transcribed spacer region 1 (ITS1) of the ribosomal DNA were used to determine the phylogenetic relationships of species of Trichoderma sect. Pachybasium. To this end, 85 strains-including all the available ex-type strains-were analyzed. Parsimony analysis demonstrated that the section is nonmonophyletic, distributing the 85 strains among three main groups that were su...
