An electron microscopy study of yeast cytochrome b2has been performed on two different crystalline forms by negative staining and freeze-etching. The overall dimensions of the tetrameric molecule were deduced from the study of the trigonal (DNA-free)

A screening of five lipases was carried out for the synthesis of wax esters from stoichiometric amounts of oleyl alcohol and milk fat in which long-chain fatty acid content (myristic acid, palmitic acid, stearic acid, and oleic acid) represents 70% o

Three androgenic DATURA INNOXIA Mill. (Solanaceae) plants which had been characterised in regard to their tropane alkaloid levels were micropropagated through axillary buds. The alkaloid contents in the leaves of more than 300 micropropagated plants

The effect of PEG and other polyols additives on cyclodextrins (CDs) production by Bacillus macerons cyclomaltodextrin-glycosyl-transferase (CGTase) was investigated. Mannitol, glycerol and PEG-200 (20%,v/v) enhanced the enzymatic production yield re

The physiological behaviour of Pseudomonas fluorescens strain R2fN was compared to that of transconjugants [R2fN(RP4)], and two aggregation phenotypes were identified (Agr- and Agr+). Agr+ phenotype is characterized by the appearance of macroscopic a

Because microorganisms frequently live in an immobilized state in natural habitats, a cell-confined system was used to study bacterial conjugation. Two Pseudomonas putida strains were introduced together within calcium alginate gels. Different algina

A nuclear magnetic resonance (NMR) method has been developed to monitor on-line lipase-catalyzed esterification reactions without the need to sample the reaction medium. The technique, through (1)H NMR, measures the concentrations of alcohol, ester,

The mutant Rhizobium meliloti M5N1CS (NCIMB 40472) produced a partially acetylated (1--4)-beta-D-glucuronan during fermentation. The polysaccharide (EPS) extracted from broth during fermentation by microfiltration and ultrafiltration (using a 100 kDa

Chloroplast membranes were isolated in different media containing Hepes [4-(2-hydroxyethyl)-1-piperazine-ethanesulphonic acid] and high concentrations of sorbitol (0.33 M), potassium citrate (0.75 M) or Na2SO4 (1.0 M). Due to the complexity of the me
