Attachment of agrobacteria to grape cells

Article Abstract:

Attachment of agrobacteria to grape cells is blocked by the a virulent strain HLB-2 in both the tissue culture cell suspension and the seedling root systems, and this attachment could be affected by a number of receptors exposed on the host cell surface. The low percentage of attachment, 10 to 25 percent, for Ji plasmid-beaning isolates and HLB-2 indicates a paucity of sites. Experiments showed that low levels of bacteria incurred frequently in the inocula.

Detection of low levels of Listeria monocytogenes cells by using a fiber-optic immunosensor

Article Abstract:

The objective of the study was to develop a fiber-optic immunosensor and optimize conditions that would be able to detect viable Listeria monocytogenes cells from ready-to-eat meat samples in less than 24 h from the point of food sampling. Results of the study indicates that the fiber-optic sensor can detect L. monocytogenes from enriched RTE meat samples with initial low levels of contamination in under 24 h.

Use of whole cells of pseudomonas aeruginosa for synthesis of the antioxidant hydroxytyrosol via conversion of tyrosol

Article Abstract:

A new biosynthesis method that consists of whole-cells of pseudomonas aeruginosa as catalysts and which is used for the synthesis of large quantities of the antioxidant hydroxytyrosol, and which takes place through the conversion of tyrosol is developed. This method helps in achieving hydroxytyrosol in an environmental friendly way and can be used for laboratory as well as industrial applications.
