Haematococcus pluvialis can produce and accumulate large
amounts of astaxanthin under stress conditions. In this
study we investigated influence of different concentrations
of azide (0, 25, 50 and 100 μM), in two-time periods (pretreatment-
7 days and treatment- 14 days) to compare
the changes on growth and biochemical parameters in
green and red stages. Azide treatment and preptreatment
caused a decrease in all measured parameters except of
carotenoid in green stage. Carotenoid content did not show
any changes in azide treatment but pre-treatment with low
concentration induced carotenoid accumulation in green
stage. The amount of dry weight, protein and carbohydrate
did not change in red cells that had treated with azide, but
carotenoid content decreased in these cells. Pre-treated with
azide had a negative effect on the amount of protein and
carbohydrate but increased the carotenoid content. Azide
pre-treatment had better performance in increasing the
amount of carotenoids in red cell. These results show that
H. pluvialis offer potential to phytoremediation of azide and
carotenoid accumulation.

Kluyveromyces fragilis has a place with the Ascomycetes class, which incorporates families that produce endospores and mycelia without clamp associations. Ascomycetes dont produce urease, yet they ferment explicit saccharides. Kluyveromyces fragilis is utilized for biotechnological processes due to its ability to ferment lactose using lactose permeases

We hereby present a retrospective analysis of clinical
data collected from the coronavirus disease (COVID)
positive patients admitted to our Centre for treatment.

In order to contain the spreading of newly emerged SARS-CoV-2, one or more of the following approaches are required: destabilizing the virion in the environment, disrupting its recognition and entry to host cells, and interfering with its replication inside host cells. Previous research has successfully identified some means to inactivate airborne virions and virion-contaminated surfaces
