The factors which determine the specific positions at which steroids are hydroxylated by micro-organisms are being investigated, using mono-ketones or keto-alcohols of the androstane series as substrates and infra-red and n.m.r. spectroscopy to determine the structures of the products. Whereas the major product of the hydroxylation of 5o-androstan-3-one by cultures of Calonectria decora is 123,...

A comprehensive phylogenetic reassessment of the ascomycete genus Cosmospora (Hypocreales, Nectriaceae) is undertaken using fresh isolates and historical strains, sequences of two protein encoding genes, the second largest subunit of RNA polymerase II (rpb2), and a new phylogenetic marker, the larger subunit of ATP citrate lyase (acl1). The result is an extensive revision of taxonomic concepts,...
