Genome drafts of spp. from soil and sediment of Mount Makiling, a dormant volcano in the Philippines.

We present the draft whole-genome sequences of spp. isolated from the soils and sediments of Sipit Creek located at Mount Makiling, a dormant volcano in the southern part of Luzon Island, Philippines. This P spp.

Phytotoxicity of the tetramic acid metabolite trichosetin.

Trichosetin, a tetramic acid-containing metabolite produced in the dual culture of Trichoderma harzianum and Catharanthus roseus (L.) G. Don callus, was subjected to phytotoxicity assays.

Trichosetin, a novel tetramic acid antibiotic produced in dual culture of Trichoderma harzianum and Catharanthus roseus Callus.

The dual culture of Trichoderma harzianum and Catharanthus roseus callus produced an antimicrobial compound with a remarkable activity against the Gram-positive bacteria Staphylococcus aureus and Bacillus subtilis. Structural elucidation revealed that this compound, which we have named trichosetin, is a novel tetramic acid (2,4-pyrrolidinedione) antibiotic and a homolog of the fungal metabolite equisetin. This compound however, was not produced in the individual culture of T.
