Protection mechanism by lignin additives for baculoviruses against the negative effect of uv radiation
|
|
| Abstract |
The virus suspension containing 1% of any of the tested lignin additives had almost the same pH value of around 7.55. Therefore, it was difficult to state that the pH valuc of lignin additive played a key role in protecling the virus.
The speclrophotometer tests, showed also that, all the lignin additives were similar in their high rate of UV-absorption (from 210-900 nm), especially in the mosl effectivc UV inactivation region (300-320 nm). Scaning Electronmicrograph (SEM) of polyhedra combined with the lignin additive indicated the possibility of physical protection of the polyhedra by the tested additive. The latter appeared to syrround the polyhedra with a continuous layer which was visible in the dark field of transmission electromicroscopic examination.
