Biotransformation of limonene and related compounds by aspergillus cellulosae
Abstract The biotransformation of (+)-, (−)- and (±)-limonenes by Aspergillus cellulosae M-77 has been investigated. (+)-Limonene was transformed mainly to (+)-isopiperitenone, (+)-limonene-1,2-Expand
Biotransformation of (−)‐(R)‐α‐Phellandrene: Antimicrobial Activity of Its Major Metabolite
The metabolite 5‐p‐menthene‐1,2‐diol showed moderate‐to‐good inhibitory activities against various bacteria and especially against Candida species in comparison with its substrate (−)‐(R)‐α‐phellandrene and standard antimicrobial agents. Expand
Eucalyptus as Biomass. Novel Compounds from Microbial Conversion of 1, 8-Cineole
Conversion of 1, 8-cineole (1) by a strain of Aspergillus niger was investigated in connection with the biomass utilization of Eucalyptus plants. Two novel alcohols, 3-exo-(5) andExpand
Ferulagone: a new monoterpene ester from Ferulago thirkeana essential oil.
Biological activities of the essential oil and the purified major component were tested against various human pathogenic microorganisms resulting in moderate inhibition. Expand
Biotransformation of monoterpenoids, (−)- and menthols, terpinolene and carvotanacetone by Aspergillus species
Abstract Four monoterpenoids, (−)- and (+)-menthols, terpinolene and carvotanacetone were biotransformed by Aspergillus niger and several related species. Aspergillus niger converted (−)-menthol toExpand
The essential oil constituents and antimicrobial activity of Anthemis aciphylla BOISS. var. discoidea BOISS.
The biological activity of the essential oils was evaluated in various human pathogenic microorganisms using the broth microdilution method and an unknown component isolated from the essential oil was characterized by means of MS, HR-MS, FT-IR, 1D- and 2D-NMR techniques as isofaurinone. Expand
Biotransformation of citrus aromatics nootkatone and valencene by microorganisms.
Biotransformations of the sesquiterpene ketone nootkatone from the crude drug Alpiniae Fructus and grapefruit oil, and the sESquiterPene hydrocarbon valencene from Valencia orange oil were carried out with microorganisms to afford structurally interesting metabolites. Expand
Microbial transformation of dehydropinguisenol by Aspergillus sp.
Two metabolites were obtained by microbial transformation of a furanosesquiterpene alcohol, dehydropinguisenol and lejeuneapingu Eisenol, using Aspergillus niger and As pergillus cellulosae using a possible pathway for the formation of these compounds is discussed here together with their antimicrobial activity against A. niger.

Conversion of (-)-Carvone by Strains of Streptomyces, A-5-1, and Nocardia 1-3-11
Many actinomycetes, newly isolated from soil, converted (−)-carvone to either (−)-trans-carveol or (−)-cis-carveol or to a mixture of both compounds, and known metabolic products, such asExpand
