Production of β-carotene by aRhodotorula strain grown on sugar cane juice

Production of β-carotene by aRhodotorula strain grown on sugar cane juice Biotechnology Letters Vol 12 No 3 207-208 (1990) Received as revised 9th February PRODUCTION OF b-CAROTENE BY A RHODOTORULA STRAIN GROWN ON SUGAR CANE JUICE H.L. MATELLI*; I.M. da SILVA, N.O. SOUZA e D~ POMEROY Departamento de Engenharia Bioqu[mica Escola de Qu[mica, Universidade Federal do Rio de Janeiro 21941 - Rio de Janeiro, R.J., BRASIL. INTRODUCTION Earlier papers sugested a number of media for improving the concentration of carotenoids in yeast cells (Simpson et al., 1971). Two recent papers reported results on biomass production and improvement of E-carotene concentration by Rhodotorula strain growing on a synthetic medium (.Costa et al., 1984, Costa et al., 1987). Sugar cane juice is abun- dantly produced in tropical countries and used for producing sugar and alcohol. Here we report the production ~-carotene with this strain growing in sugar cane juice. MATERIAL AND METHODS Sugar cane juice compositon in g/l: total solids 230, sucrose 205, protein 4.0, ash 2.4; pH 5.5. Fresh juice was dispensed in conical flasks and held at 80oc for 20 minutes, cooled and stored at 5oc. For fermentations, the juice was filtered and diluted to 22-25 g/l of sucrose and nutrients added in g/l: (NH~)2SO4 5.3; KH2PO45.5; Na2HPO4 3.7; MgSO4. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Biotechnology Letters Springer Journals
