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 ...

In this study seven new species of the Botryosphaeriaceae are described from baobab (Adansonia gibbosa) and surrounding endemic tree species growing in the Kimberley region of northwestern Australia. Members of the Botryosphaeriaceae were predominantly endophytes isolated from apparently healthy sapwood and bark of endemic trees; others were isolated from dying branches. Phylogenetic analyses o...

We describe a case of subcutaneous infection as a result of traumatic implantation caused by the fungus Lasiodiplodia theobromae. It was isolated in multiple swabs from the foot of an active healthy male. The fungus was identified by traditional mycology culture methods though this was slow with much time required for sporulation on only one of the agars used. Identification was confirmed by DN...

Due to the lack of availability of unnatural (+)-quinic acid as a starting material, a 6-step synthesis of butane diacetal-protected (4S,5S)-dihydroxycyclohexen-1-one (formally derived from (+)-quinic acid) has been devised. The key catalytic asymmetric step involves a chiral Co-salen-catalysed epoxide ring-opening reaction. (4S,5S)-Dihydroxycyclohexen-1-one was utilised in the synthesis of two...

The aim of this study was to evaluate the effects homeopathic medicine Calcarea carbonica 12CH and bioproducts: filtrates saprobic fungi from Amazon, green propolis nosode 06CH, filtrate Pichia sp., extract, Bacillus subtilis; control Lasiodiplodia (Lasiodiplodia sp.) development passion fruit seedlings (Passiflora edulis Sims f. flavicarpa Degener). experiment carried out in a completely rando...
