Abstract
In order to devise a new technique for sustainable ethylene production, we identified ethylene-producing microorganisms, and investigated the microbial activities on ethylene production from dead grape leaf (DGL) lipids.
Seventy-eight kinds of the microorganisms were isolated from approximately 450 soils in various regions.
From a viewpoint of morphological and molecular biology, we identified 16 strains of fungi (Penicillium citrinum KIOBRA1, Aspergillus sclerotiorum KIOBRA2, Penicillium pinophilum KIOBRA3, Gongronella butleri KIOBRA11, Aspergillus tamari KIOBRA12, Eupenicillium shearii KIOBRA13, Monascus purpureus KIOSF1, Absidia corymbifera KIOSF2, Rhizomucor pusillus KIOSF3, Penicillium commune KIOSF4, Trichoderma hamatum KIOSF5, Verticillium coccosprum KIOSF6, Penicillium ochrochloron KII1, Umbelopsis isabellina KII2, Cunninghamella ochia KII3, Penicillium adametzii KII4) and 6 strains of bacteria (Bacillus sphaericus KIOSB15, Bacillus sp.
KIOSB17, Bacillus bataviensis KIOSB21, Bacillus sp.
KIOSB29, Bacillus mycoides KIOSB43, Bacillus megaterium KIOSB44). Both the fungi and the bacteria produced large amounts of ethylene from DGL lipids.
The amount of ethylene by the bacteria was greatly higher than that by the fungi.
In particular, these bacteria produced approximately 0.3 ml ethylene from 1 g of DGL lipids for 3 d, and this active evolution remained for 1 month.
Huge quantities of ethylene evolved from DGL lipids by microorganisms will contribute to industrial use as well as horticultural use.
