“…Therefore, the use of surface-adsorbed cells as biocatalysts is receiving considerable in-terest Rouxhet 1984, 1985;Flygare and Larsson 1987;Buchs et al 1988;E1-Aassar et al 1988). Immobilization of cells by adhesion to a solid support can reduce or eliminate mass transfer problems associated with the commonly used gel entrapment techniques.…”

Living cells of Mycobacterium sp. NRRL B-3683 were immobilized by adsorption on different types of solid carriers in order to produce androsta-1,4-diene-3,17-dione (ADD) from cholesterol. Activated alumina proved to be the most preferred carrier for long-term operation when glucose and peptone were added to the reaction medium. In a repeated-batch process, the maximum productivity of ADD was about 0.19 g/l per day with a molar conversion rate of 77% when 1.0 g/l of cholesterol was added to the reaction medium. The half-life of the immobilized cells was more than 45 days and the system could be reactivated by incubating the immobilized cells in a cell growth medium.

“…There is evidence that in the laboratory artificially immobilized hydrocarbon-degrading microorganisms still maintain their hydrocarbon biodegradation potential (Heinrich & Rehm 1981, El-Assar et al 1988. In the early 1990s we reported on the first naturally immobilized consortium of hydrocarbon-degrading microorganisms on the Arabian Gulf coasts (Sorkhoh et al 1992).…”

This paper reports on hydrocarbon-degrading microbial consortia immobilized in biofilms on gravel particles in the intertidal zone of the Arabian Gulf coast. These microorganisms contribute to the self-cleaning of the coasts and, in addition, could potentially be used for cleaning oily industrial waste before its disposal in the open environment. Each gravel particle was found coated with about 100 mg biofilm of blue-green biomass. The predominant phototrophs were the cyanobacteria Dermocarpella and to a lesser degree Lyngbya sp. The most dominant hydrocarbondegrading bacterium in this consortium was Acinetobacter calcoaceticus; minor bacteria included Micrococcus and nocardioforms. The biofilm-coated gravel particles were used in 5 successive cycles of purification of oily sea water. This immobilized microflora was efficient during all cycles in hydrocarbon consumption. In contrast, bacteria adhering to biomass-uncoated gravel particles brought about hydrocarbon degradation in the first few cycles, but then gradually lost their cleaning potential, apparently due to their successive washing out from the particles during successive cycles.

“…For example, while Candida parasilosis 86 , C. intermedia 87 , and Lodderomyces elongisporus 88 hydroxylate a terminal methyl group of n-alkanes, Candida lipolytica hydroxylates the terminal methyl and C-2 methylene groups 89 . Regarding fungal hydroxylation of n-alkanes, Cladosporium resinae hydroxylates a terminal methyl group 90 , while Cunninghamella blakesleeana hydroxylates both terminal methyl and subterminal methylene groups of n-alkanes 91 .…”
