Nodularin (NOD) is greatly produced by Nodularia spumigena and released into the environment when toxic cyanobacterial blooms happened in natural water body, which is seriously harmful to human and animals. The promising bacterial strain of Sphingopyxis sp. USTB-05 was found to have an ability in biodegrading NOD. Initially, 11.6 mg/L of NOD could be completely eliminated within 72 h by whole c...

the effects of different sources of carbon, nitrogen and some of trace elements on cultivation of bacillus thuringiensis h14 were studied. glucose, glycerol, sodium acetate, (nh4)2so4, corn steep liquor, yeast extract, hydrolyzed casein, ca2+, mg2+ and mn2+ were the main parameters evaluated by plackett-burman statistical method. all elements have insignificant effect on germination while spore...

in order to micropropagate of four vigorous rootstocks of pear, including pyrus betulifolia, konjuni, dargazi and gh1, effects of basic plant culture media (ms, ql and modified ql), cytokinins and auxins on productivity, proliferation and rooting were studied in seed and plant improvement institute, karaj. the highest amount of productivity for all rootstocks was observed in ql medium. among pe...

Elevated blood alcohol content (BAC) on admission is associated with poorer outcomes, larger burns and more inhalation injury. This study's purpose was to examine the effects of alcohol through a matched case-controlled study, measuring early and extended markers of clinical outcomes. The hypothesis was that patients with an elevated admission BAC would require more resuscitation and have a lon...

the postharvest life of cut eustoma grandiflorum flowers is limited in open flowers. therefore a factorial experiment based on a completely randomized design with ascorbic acid (asa) at 4 levels (0, 100, 200, 300mg l-1) and citric acid (ca) at 3 levels (0, 100, 200 mg l-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. results indicated that a significa...

The aim of the present study was to evaluate the effect of rosemary (Rosmarinus officinalis L.) powder and vitamin E, as feed additives combined at different levels, on oxidative stability of broiler meat up to 14th day after chilling. A total of 270 1-day-old male chicks of Ross 308 strain were randomly assigned to nine dietary groups with three replicates having 10 birds each. Diets were supp...

Effect of gibberellic acid on marigold (Calendula Officinalis L.) was evaluated in a pot culture experiment. A factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. Main factor was foliar application stages (first, second and third) and sub factor included different concentrations of GA3 (0, 50, 150 and 250 mg L...
