In this study, we determined the genetic diversity of 126 isolates representing both Lasiodiplodia theobromae and Lasiodiplodia pseudotheobromae, collected from Theobroma cacao and Terminalia spp. in Cameroon, using simple sequence repeat (SSR) markers. SSR alleles showed clear genetic distinction between L. theobromae and L. pseudotheobromae, supporting their earlier separation as sister speci...

An administration study of (2)H-labeled precursors showed that the 9-hydroxydecanoyl unit, the acyl intermediate of lasiodiplodin (1), was also the intermediate of (5S)-5-hydroxylasiodiplodin (2) in Lasiodiplodia theobromae. The incorporation of [O-methyl-(2)H(3)]-lasiodiplodin (6) into 2 indicated that hydroxylation at C-5 occurred after cyclization.

The present study focuses on fungal strains capable of secreting extracellular enzymes by utilizing hydrocarbons present in the contaminated soil. Fungal strains were enriched from petroleum hydrocarbons contaminated soil samples collected from Chennai city, India. The potential fungi were isolated and screened for their enzyme secretion such as lipase, laccase, peroxidase and protease and also...

Two novel resorcinol derivatives were isolated from the mycelium of Lasiodiplodia theo­ bromae IFO 31059 as potato micro-tuber inducing compounds. Their structures were estab­ lished by spectroscopic methods as ethyl (6 ' 7?)-2,4-dihydroxy-6-(6'-hydroxyheptyl)benzoate (8) and isobutyl (6 ' /?)-2.4-dihydroxy-6-(6'-hydroxyheptyl)benzoate (9). The absolute stereo­ chemistry of the asymmetric cente...

The transformation of 22-hydroxy-23,24-bisnorchol-4-en-3-one to 7a-22-dihydroxy-23,24-bisnorchol-4-en3-one by Botryodiploida theobromae, Lasiodiplodia theobromae, and various Botryosphaeria strains is described. Factors affecting the reaction were incubation temperature, sonication of the substrate, and addition of 2,2'-dipyridyl, extra carbohydrate, and Amberlite XAD-7. The enzyme responsible ...
