The present invention provides a process for the production of p-cresol in a quantitative yield, which involves the acidification of an aqueous solution of the starting, material, 4- methyleyclohexa-3,5-diene-I, 2-diol-l- carboxylic acid, under ambient conditions of temperature and pressure to cause spontaneous decomposition of the starting material to p- cresol. The starting material is produced with Pseudomonas putida Biotype A strain ATCC 39119.

Fermentative or enzymatic production of 2- keto-L-gulonic acid from 2, 5-diketo-D-gluconic acid using living or processed mutants, being defective in metabolizing 5-keto-D-gluconic acid and incapable of producing 2-keto-D-gluconic acid. The mutant is derived from 2-keto-L- gtuconic acid producing microorganisms of genus Corynebacterium. The production is car- ried oat in the presence of nitrates and/or hydro- gen donors in a preliminarily sterilized fermentation broth in which a 2, 5-diketo-D- gluconic acid producing microorganism ofgenRs Gluconobacter or Erwinia has been cultivated.

carbohydrate-containing substrate liquid through a vessel packed with a thin film means having yeast immobilized therein. Surfaces of the thin film means extend in the direction of flow within the vessel to provide elongated para- llel passages. The thin film means occupies from 10 to 65°0 of the volume of the vessel and pre- ferably has a thickness of 0.1 to 3 ram. Pre- ferably, the thin film means is formed by mixing an aqueous yeast suspension with a photo- crosslinkable resin and subjecting the mixture to radiation to photo-crosslink the resin.

A novel antibiotic complex of Vancomycin-like antibiotics, AAD 216 complex, is produced by the cultivation of a fermentation broth con- taining Kibdelosporangium aridum Shearer gen. nov., sp. nov. ATCC 39323 microorganisms in an aqueous nutrient medium under submerged aerobic conditions. The AAD 216 complex and its major bioactive components; AAD 216A, AAD 216B, and AAD 216C exhibit antibiotic activity and growth promotant activity.
