Bacterial specialized metabolites are increasingly recognized as important factors in animal–microbiome interactions: for example, by providing the host with chemical defenses. Even in chemically rich animals, such compounds have been found to originate from individual members of more diverse microbiomes. Here, we identified a remarkable case of a moderately complex microbiome in the sponge host Mycale hentscheli in which multiple symbionts jointly generate chemical diversity. In addition to bacterial pathways for three distinct polyketide families comprising microtubule-inhibiting peloruside drug candidates, mycalamide-type contact poisons, and the eukaryotic translation-inhibiting pateamines, we identified extensive biosynthetic potential distributed among a broad phylogenetic range of bacteria. Biochemical data on one of the orphan pathways suggest a previously unknown member of the rare polytheonamide-type cytotoxin family as its product. Other than supporting a scenario of cooperative symbiosis based on bacterial metabolites, the data provide a rationale for the chemical variability of M. hentscheli and could pave the way toward biotechnological peloruside production. Most bacterial lineages in the compositionally unusual sponge microbiome were not known to synthesize bioactive metabolites, supporting the concept that microbial dark matter harbors diverse producer taxa with as yet unrecognized drug discovery potential.

The natural product pateamine A (pateamine) from the sponge Mycale hentscheli is active against a wide range of dividing cells and has been shown to inhibit the functions of the eukaryotic initiation factor 4A (eIF4A). We have identifi ed that pateamine is additionally able to modulate the formation of actin fi laments and microtubules in vitro but at higher concentrations than required for inhibition of eIF4A. Cell cycle analysis confi rmed that actin and tubulin are not major mediators of the cellular activity of pateamine. The range of targets identifi ed demonstrates the value of multiple approaches to determining the mode of action of biologically active compounds

The species of the cosmopolitan sponge genus Mycale occurring in the tropical Indo-West Pacific region and adjacent subtropical waters are reviewed taxonomically. Specimens incorporated in the collections of the Naturalis Biodiversity Center form the basis of this comprehensive study, supplemented by (type) specimens borrowed from or examined in other institutions. Specimens available numbered 351, belonging to 44 species, including 14 species new to science, Mycale (Aegogropila) prognatha sp.nov., Mycale (Carmia) amiri sp.nov., Mycale (Carmia) fungiaphila sp.nov., Mycale (Carmia) monomicrosclera sp.nov., Mycale (Carmia) tenuichela sp.nov., Mycale (Carmia) tubiporicola sp.nov., Mycale (Carmia) tydemani sp.nov., Mycale (Mycale) asigmata sp.nov., Mycale (Mycale) grandoides sp.nov., Mycale (Mycale) sundaminorensis sp.nov., Mycale (Naviculina) mascarenensis sp.nov., Mycale (Paresperella) sceptroides sp.nov., Mycale (Paresperella) seychellensis sp.nov., Mycale (Zygomycale) sibogae sp.nov. Three species, indicated by the designation ‘aff.’, were not definitely assigned to known or new species due to uncertainty of their identity. The genus Kerasemna, previously considered a junior synonym of Mycale, was revived as an additional subgenus Mycale (Kerasemna). One species, previously assigned to the genus Desmacella as D. lampra De Laubenfels is here reassigned to Mycale, subgenus at present undecided. Additionally, species previously reported from the region but not represented in our collections are briefly characterized and discussed. We propose new names Mycale (Mycale) mauricei nom.nov. for Mycale macrochela Burton (junior primary homonym of Mycale fistulata var. macrochela Hentschel) and Mycale (Mycale) bouryesnaultae nom.nov. for Mycale (Mycale) fibrosa Boury-Esnault & Van Beveren (junior primary homonym of Mycale (Aegogropila) adhaerens subsp. fibrosa Koltun). Keys to the species of each subgenus occurring in the region are provided. The opportunity of having studied this comprehensive set of species and specimens from the tropical Indo-West Pacific is taken to review and discuss the morphological and biogeographical data gathered so far on the genus Mycale. The genus currently comprises approximately 255 accepted species, with highest diversity focused in tropical Atlantic and Indo-West Pacific regions as well as in warm-temperate Mediterranean-Atlantic regions.

Sponge samples were taken by SCUBA diving from sixteen sites on the north coast of South Georgia island, south westSouthern Ocean. Fifteen new species are described: Iophon husvikensis sp. nov., Clathria (Clathria) stromnessa sp.nov., Clathria (Axosuberites) rosita sp. nov., Clathria (Microciona) matthewsi sp. nov., Lissodendoryx (Ectyodoryx)collinsi sp. nov., Hymedesmia (Hymedesmia) barnesi sp. nov., Hymedesmia (Stylopus) pharos sp. nov., Myxilla(Burtoanchora) ponceti sp. nov., Tedania (Tedaniopsis) aurantiaca sp. nov., Tedania (Tedaniopsis) wellsae sp. nov.,Mycale (Mycale) brownorum sp. nov., Mycale (Mycale) cartwrighti sp. nov., Haliclona (Soestella) crowtheri sp. nov.,Microxina myxa sp. nov. and Calyx shackletoni sp. nov. Information is also provided on the distribution and in situexternal appearance of other sponge species such as Cinachyra barbata Sollas 1886, Polymastia invaginata Kirkpatrick1907, Iophon unicorne Topsent 1907, Phorbas glaberrimus (Topsent 1917), Myxilla (Ectyomyxilla) kerguelensis(Hentschel 1914) and Rossella nuda Topsent 1901. These results increase the previously reported low spongeendemicity in South Georgia, which now better aligns with the high endemicity of other groups. However, because wesampled areas that have been poorly sampled in the Southern Ocean / Antarctic region (shallow subtidal, rocky), manyof these species may have wider polar distributions. The effect of the Polar Front as a dispersal barrier to neighbouring biogeographic regions is discussed.
