Basic information on antibiotics and other biologically active products are presented in these two easy-to-read volumes. The first volume is devoted entirely to antibiotics and consists of data assembled from the Index of Antibiotics from Actinomycetes. Highlighted are antibiotics from bacteria and from phycomycetes and other fungi. Mutasynthetic antibiotics are also discussed. In the second volume, data on biologically active substances is presented. Antiviral compounds, pharmacologically active compounds from microbial sources and plant products not readily considered antibiotics are featured. In addition, compounds produced commercially by fermentation and some products of the "new biotechnology" are listed.
