This study examines nodulation and some aspects of N2 fixation by Casuarina equisetifolia growing in Egypt. Plants examined were 2 to 10 years of age, and all were nodulated. Nodules varied from young meristematic lobes on lateral roots to clusters occasionally reaching 10 cm in diameter; they...
The programme of protein synthesis accompanying cellular differentiation to the heterocyst following transfer of the blue‐green algae Anabaena circularis and Cylindrospermum sp. (CBSC 1755) from ammonia‐enriched medium to nitrogen‐free medium was determined by polyacrylamide gel electrophoresis...
The induction of the 4‐ene‐3‐oxosteroid: (acceptor)‐1‐ene‐oxidoreductase in Nocardia opaca has been shown to be dependent on both hydrophilic and hydrophobic structural features of the steroid molecule, i. g. the nature of the oxygen function in positions 11 and 20 and the presence of the methyl...
With several isolates of T. aquaticus rotund bodies (rbs) have been artificially induced. The most active agents were lysozyme, pronase (not trypsin), cellulase (not α‐amylase or β‐glucosidase), penicillin and some mineral salts. Two modifications of rbs were observed: the vesicular type arising...
A yeast of the genus Candida which is able to grow on n‐alkanes was characterized by biochemical investigations: Crabtree effect, inhibition of ammonium utilization by asparagine, changes in the concentration of polysaccharides mainly concentrated in the cell wall. The yeast was compared...
