Rennet was immobilized on porous glass beads (50-100 mesh) using diazotization [Paquot et al., DSA 38, 5851], TiCl4 [Barker et al., Process Biochemistry (1971) 5, 11], glutaraldehyde [Stanley & Olson, Journal of Food Science (1974) 39, 660] or glutaraldehyde followed by reduction of aldehyde groups by NaBH4 [Cheryan et al., DSA 38, 6728]. Residual enzyme activity was low using all 4 methods, being highest using TiCl4 (24.4%). After 13 days storage, loss of enzyme activity using diazotization and TiCl4 was resp. 82 and 58%. Activity of rennet immobilized using TiCl4 decreased with time during the passage of milk through the column, this being due to release of enzyme rather than denaturation. Ca2+ ions were responsible for the release; loss of enzyme activity during four 15-min passages of whey, casein solution (pH 7) and casein solution + EDTA was resp. 87, 57 and 4.5%. Precoating the glass beads with serum albumin resulted in significant increases in residual activity of rennet, particularly when immobilized using glutaraldehyde/NaBH4. This improvement diminished on storage. [less ▲]

Thin films of polypyrrole doped by polyanions have been deposited onto stainless steel and carbon fibers by anodic electropolymerization of pyrrole in the presence of an anionic polyelectrolyte in water. Films with a thickness smaller than 600 nm have been formed, which strongly adhere to the solid supports. The polymeric dopant has been selected for its ability to complex silver ions. Scanning electron microscopy, Rutherford backscattering analyses, and IR spectroscopy have confirmed that silver is actually immobilized in the films and provides them with an antibacterial activity against the Gram-negative bacteria Escherichia coli and Gram-positive bacteria Staphylococcus aureus.

Lipases are able to catalyse the hydrolysis of glyceridic esters in aqueous media and the synthesis of esters in non-aqueous media. They are thus able to catalyse numerous reactions of industrial interest. Whether it is by inclusion, by adsorption or by covalent link, the immobilisation of lipases aims at conferring them a good stability that enables a reuse of the enzymes after a reaction and the development of continuous processes. The reactions of triglycerides hydrolysis constitute main applications for immobilised lipases, however their use in different types of esterification reactions has also arose: there exist processes involving reactions of transesterification, of interesterification or of esters synthesis. The production of structured lipids by interesterification is one example. Although the reaction conditions dissent from those of hydrolysis, the same lipases have been used in both cases. A lipase specifically adapted for esterification though would be a highly capable tool: a series of strategies is in progress in order to reach this goal. [less ▲]

Ten immortalized cell lines were established by transfection of human cervical keratinocytes (CK) with HPV-33 DNA and some of their characteristics were investigated. The following observations were made: (a) several cell lines have reached over 100 population doublings in vitro; (b) 3 transcripts were observed, 2 being encoded by the E6/E7 open reading frames (ORFs); (c) cytogenetic analyses showed important genetic modifications such as aneuploidy and isochromosome formation of the q arm of chromosome 8; (d) 2 of the 10 cell lines developed colonies in soft agar but none was able to form tumors when injected s.c. into nude mice; (e) Southern analysis suggested that a single copy of HPV-33 is integrated at a single common site within the genome of the 10 cell lines. These immortalized cell lines should be useful for studying mechanisms involved in proliferation, differentiation and neoplastic transformation of CK by HPV-33. [less ▲]

As the inbred mouse strain SJL/J displays increased resistance to several pathogens and as its immune system shows multiple specificities, it is tempting to infer a causal link between these observations. The first question that comes to mind is whether adaptive immunity plays a role, and a way to answer this question is to see if the resistance phenotype persists when adaptive immunity is depressed. Although it has long been known that irradiation causes repression of leukopoiesis in mice, the technical data available in the literature are of no help in the case of strain SJL/J, because it displays exceptional radioresistance. Here we show that exposure of SJL/J to ∼9Gy, an intensity corresponding to the lethal dose 50 for the species Mus musculus, leads to serious but reversible alteration of leukopoiesis. This conclusion stems from an examination of the effects, 1-11 days post-exposure, of whole-body gamma-ray irradiation on leukocyte populations in the thymus and peripheral blood of young adult females. Immunodepression was most severe 4 days post-exposure. As in other strains, leukocyte populations displayed differential radiosensitivity, B (CD19(+)) cells being most sensitive, T (CD4(+)/CD8(+)) cells moderately sensitive, and natural killer (NK1.1(+)) cells most resistant. Surprisingly, however, the helper/inducer T lymphocytes proved more resistant than the cytotoxic/suppressor T lymphocytes, contrarily to what is observed in other strains. The procedure described will make it possible to refute or establish reliably the existence of causal links between SJL-specific phenotypic traits and immune aberrations and to elucidate further the respective roles of innate and acquired immunity in determining the resistance of this strain to an array of viral diseases.
