background and aims: virus-induced gene silencing (vigs) is a virus vector technology that exploits antiviral defense mechanism. by infecting plants with recombinant viruses containing host genes inserted in the viral genome, vigs achieves the rna silencing process. the purpose of this study was to investigate the possibility of tomato (lycopersicon esculentum mill.) and tobacco (nicotiana bent...

abstract: fermented cucumber is a traditional lactic acid fermentation that is related to the presence of microorganisms. in this study, the use of suitable l. plantarum starter culture with l.bulgaricus and s. thermophilus to improve the cucumber fermentation process with high quality has been studied. cucumbers in brine containing 4 to 6% nacl and 0.2 to 0.4% inulin (w/v) were inoculated with...

A hydrogen utilizing exoelectrogenic bacterium (Geobacter sulfurreducens) was compared to both a nonhydrogen oxidizer (Geobacter metallireducens) and a mixed consortium in order to compare the hydrogen production rates and hydrogen recoveries of pure and mixed cultures in microbial electrolysis cells (MECs). At an applied voltage of 0.7 V, both G. sulfurreducens and the mixed culture generated ...

Production of biphenomycin A by Streptomyces griseorubiginosus 43708 was stimulated by a mixed culture with a partner strain, Pseudomonas maltophilia 1928. This stimulatory effect on biphenomycin A accumulation by the mixed culture was caused by the enzyme activity which strain 1928 possessed. It is suggested that in a mixed culture strain 43708 produces a precursor of biphenomycin A in culture...

1) It has been found that the peripheral blood of hybrid adult dogs contains about 29.4 % of lymphocytes in average. When such a blood is passed through the glass wool column the leucocytes containing 68-90 % (81.6% in average) lymphocytes are obtained. 2) In the single culture of such lymphocytes alone and mixed culture both live lymphocytes and sonicated lymphocytes in the presence of 1% (vIv...

polyhydroxyalkanoates (phas) is known to be temporarily stored by microorganisms in activated sludge, especially in the anaerobic-aerobic processes. the main objective of this study was to investigate the effects of fatty acids (vfas) compounds coexistence in substrate of sbr on phas productivity of activated sludge. it has been found that addition of different concentrations of vfas results in...

CONTEXT Mixed lymphocyte culturing has led to conflicting opinions regarding the selection of donors for bone marrow transplantation. The association between a positive mixed lymphocyte culture and the development of graft-versus-host disease (GVHD) is unclear. The use of exogenous cytokines in mixed lymphocyte cultures could be an alternative for increasing the sensitivity of culture tests. ...

Cellular responses in vitro to H-2D region histocompatibility antigens were demonstrated to be under the genetic control of two or three (P = 0.013) independently segregating loci. The H-2 region itself accounts for one of these loci, however, its activity appears to be dependent upon an association with other non-H-2-associated genetic information. The ability to stimulate a response and to re...
