Abstract
The taxonomic positions of two novel aerobic, Gram-positive actinobacteria, designated strains RB29T and RB68T, were determined using a polyphasic approach. Based on 16S rRNA gene sequence analysis, the closest phylogenetic neighbours of RB29T were identified as Actinomadura rayongensis DSM 102126T (99.2 % similarity) and Actinomadura atramentaria DSM 43919T (98.7 %), and for strain RB68T was Actinomadura hibisca DSM 44148T (98.3 %). Digital DNA-DNA hybridization (dDDH) between RB29T and its closest phylogenetic neighbours, A. rayongensis DSM 102126T and A. atramentaria DSM 43919T, resulted in similarity values of 53.2 % (50.6-55.9 %) and 26.4 % (24.1-28.9 %), respectively. Additionally, the average nucleotide identity (ANI) was 93.2 % (94.0 %) for A. rayongensis DSM 102126T and 82.3 % (78.9 %) for A. atramentaria DSM 43919T. dDDH analysis between strain RB68T and A. hibisca DSM 44148T gave a similarity value of 24.5 % (22.2-27.0 %). Both strains, RB29T and RB68T, revealed morphological characteristics and chemotaxonomic features typical for the genus Actinomadura, such as the presence of meso-diaminopimelic acid in the cell wall, galactose and glucose as major sugar components within whole-cell hydrolysates and the absence of mycolic acids. The major phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside. Predominant menaquinones were MK-9(H6) and MK-9(H8) for RB29T and MK-9(H4) and MK-9(H6) for RB68T. The main fatty acids were identified as 10-methyloctadecanoic acid (10-methyl C18:0), 14-methylpentadecanoic acid (iso-C16:0), hexadecanoic acid (C16:0) and cis-9-octadecanoic acid (C18 : 1 ω9c). Here, we propose two novel species of the genus Actinomadura: Actinomadura rubteroloni sp. nov. with the type strain RB29T (=CCUG 72668T=NRRL B-65537T) and Actinomadura macrotermitis sp. nov. with the type strain RB68T (=CCUG 72669T=NRRL B-65538T).

Abstract
Beauvetetraones A–C, phomaligadione-derived polyketide dimers, were isolated from the entomopathogenic fungus Beauveria bassiana using LC/MS-guided isolation and their putative biosynthetic pathway is proposed.

Abstract
The chemical analysis of insect-associated Actinobacteria has attracted the interest of natural product chemists in the past years as bacterial-produced metabolites are sought to be crucial for sustaining and protecting the insect host. The objective of our study was to evaluate the phylogeny and bioprospecting of Actinobacteria associated with fungus-growing termites. We characterized 97 Actinobacteria from the gut, exoskeleton, and fungus garden (comb) of the fungus-growing termite Macrotermes natalensis and used two different bioassays to assess their general antimicrobial activity. We selected two strains for chemical analysis and investigated the culture broth of the axenic strains and fungus-actinobacterium co-cultures. From these studies, we identified the previously-reported PKS-derived barceloneic acid A and the PKS-derived rubterolones. Analysis of culture broth yielded a new dichlorinated diketopiperazine derivative and two new tetracyclic lanthipeptides, named rubrominins A and B. The discussed natural products highlight that insect-associated Actinobacteria are highly prolific natural product producers yielding important chemical scaffolds urgently needed for future drug development programs.
