Characterization of a new mitochondrial plasmid from Fusarium proliferatum.

A 10.3kb linear mitochondrial DNA plasmid designated pFP1 was isolated from Fusarium proliferatum. The DNA sequence of the plasmid consists of 10,336bp with perfect terminal inverted repeats of 400bp.

Mitochondrial DNA organisation of the mtDNA type 2b of Aspergillus tubingensis compared to the Aspergillus niger mtDNA type 1a.

A physical and functional map of Aspergillus tubingensis mtDNA type 2b was constructed and compared to Aspergillus niger typeI a mtDNA. The gene content and order, as well as the patterns of restriction sites, were similar. Two unidentified ORFs and several repeat elements were found in the region between the ndhl and ndh4 genes on both mtDNAs.

Thermobifida cellulolytica sp. nov., a novel lignocellulose-decomposing actinomycete.

Four actinomycete strains, isolated from the overheated region of manure compost, were assigned to the genus Thermobifida on the basis of morphological, physiological and biochemical characteristics. All strains produced single, ovoid, heat-sensitive spores on dichotomically branched aerial hyphae. On the basis of chemotaxonomic traits, these isolates showed strong affinity towards members of the genus Thermobifida.
