Abstract

A strain of Aspergillus sp. is described and proposed as a new species under the name ‘Aspergillus insulicola sp. nov.’ Montemayor & Santiago, 1973. This strain was isolated from soil samples taken in ‘Aves Island’ during a scientific expedition. — Aves Island, situated at 15°, 40′, 42″ N and 63°, 36′, 47″ W, about 665 Km of the coast of Venezuela, has very special ecological conditions. Due to its smallness: 550 m long and 40 to 120 m across and to its low profile only 3 m over sea level, it is swept by the sea during the periodical storms and hurricanes in the area. It has thus a very interesting fauna and flora.

We took a series of soil samples to study its mycological flora. Forty samples were inoculated by dilution method.

In this first paper a species is described and proposed as a new species because of its macroscopic and microscopic characteristics, as well as by its biological properties, under the name ‘Aspergillus insulicola sp. nov.’. In its study we have tried to follow as closely as possible the methods recommended by Kennet B. Raper & Dorothy Fenell, world authorities on the genera Aspergillus and Penicillium. The strain is being kept in USB under the number T1, and has been sent to ATCC & CBSC to be incorporated in their collections.

Zusammenfassung

Man beschreibt eine neue Species Aspergillus unter dem Namen ‘Aspergillus Insulicold’. Sie wurde gefunden während einer wissenschaftlichen Expedition auf der Insel ‘Las Aves’ die 15° 4′ 45″ Breitegrad Nord und 63° 36′ 47″ Längengrad West von Greenwich liegt.

Es ist eine entlegene venezolanische Insel, die ungefähr 665 Km. vom Festland La Guaira entfernt ist; es ist eine der interessantesten Orte ganz besonders durch ihre sehr speziellen ecologischen Zustände, und ausserdem durch die sehr geringe Oberfläche der Insel, die nur 550 m. lang, 40 bis 120 m. breit und kaum 3 m. hoch ist. Der Boden ist sandig, und sie wird oft von Cyclonen und Meereswellen gepeitscht. Ihre Pflanzenwelt und ganz besonders ihre Tierwelt sind von einem sehr grossen ecologischen Interesse.

Wir fanden es interessant die Bioecologie der mycologischen-tellurischen Pflanzenwelt der Meeresumgebung zu studieren. Man studierte 40 Erdmuster mit Hilfe der Verdünnungsmethode. In dieser ersten Arbeit studiert und beschreibt man eine Species, die durch ihre macro- und microscopischen Eigentümlichkeiten und durch ihre biologischen Eigenschaften uns erlaubt, sie als eine neue Gattung mit dem Namen ‘Aspergillus insulicola’ zu registrieren.

Im Studium dieser Species haben wir versucht, so viel wie möglich die Methode von Kennet B. Raper und Dorothy Fennell einzuhalten.

Die Species ist in der Simon Bolivar Universität unter der Nummer T1 bewahrt und sie wurde auch der ATCC und der CBSC übergeben.
