In this study, a copper-resistant plant growth promoting bacterial (PGPB) strain Ax10 was isolated from a Cu mine soil to assess its plant growth promotion and copper uptake in Brassica juncea. The strain Ax10 tolerated concentrations up to 600 mg CuL(-1) on a Luria-Bertani (LB) agar medium and utilized 1-aminocyclopropane-1-carboxylic acid (ACC) as a sole N source in DF salts minimal medium. T...

The present study aims at establishing whether the diversity in pathogenesis within a genetically diverse host population infected with a single polyclonal strain of Trypanosoma cruzi is due to selection of specific subpopulations within the strain. For this purpose we infected Swiss mice, a genetically diverse population, with the polyclonal strain of Trypanosoma cruzi Berenice-78 and characte...

ON 3 JANUARY 1793, Watson Alcock successfully completed the examination for membership of the Company of Surgeons.1 Shortly afterwards he began his career as a surgeon in Stockton-on-Tees. It is not known if he entered an established practice but he was involved in the sale of a house with Dr. Thomas Kirton,2 who was a well-established surgeon and died soon after.

Phytoremediation can help remediate potential toxic elements (PTE) in soil. Microorganisms and soil amendments are effective means to improve the efficiency of phytoremediation. This study selected three microorganisms that may promote phytoremediation, including bacteria (Ceratobasidium), fungi (Pseudomonas mendocina), arbuscular-mycorrhizal (AMF, Funneliformis caledonium). The effects single ...

Among criteria assessing effectiveness technological methods growing crops, one important th...

INTRODUCTION The cryopreservation of rabies virus has been described in detail in the literature. To date, little information is available on the use of cryoprotective agents for cold preservation of this virus, and the available data focus only on short-term virus preservation. In this study, we investigated the medium-term cryopreservation of samples of rabies virus using different cryopreser...

A preparation of pure protoplasts of Geotrichum candidum became osmotically stable and colonies developed when the protoplasts were embedded in stabilizing thin-layer-agar and incubated with stabilizing basal medium. When growing protoplasts were exposed to distilled water and then reincubated with basal medium, the process of regeneration of protoplasts could be quantitatively demonstrated by ...

Micromonospora chalcea KY11091 produces tetrocarcin, showing antibacterial activity against Gram-positive bacteria and antitumor activity against experimental murine tumors.'-'> Tetrocarcin A, a major component, consists of a thirteen-membered macrocyclic ring containing tetronic acid (tetronolide),°> a nitro sugar (tetronitrose, the same as kijanose')) and deoxy sugars.
