This study reports the cytotoxic potential of L-Asparaginase isolated from Bacillus sp. Bacillus sp. was isolated from local soil/water samples and identified by rapid plate assay and further confirmed by phenotypic characterization. Extracellular L- Asparaginase was isolated from broth culture of Bacillus sp.  and purified by ammonium sulfate precipitation, followed by dialysis and ion exchange and gel filtration chromatography techniques. The purified enzyme was used to study the in vitro cytotoxic potential. Varying concentrations (31.25, 62.5, 125, 250, 500 µg/ml) of purified L-Asparaginase was tested on MCF7, HeLa, HepG2 and 3T3L1cell lines by MTT assay. Curcumin was maintained as a positive control. The results revealed that the enzyme showed a significant cytotoxic activity and a dose dependent effect. Minimum inhibition of (19.44%) was observed at an enzyme concentration of 31.25 µg/ml and maximum inhibition (71.14%) was observed at 500ug/ml against MCF7 cell line. Minimum inhibition of (10.04%) was observed at an enzyme concentration 31.25 µg/ml and maximum inhibition (68.92%) was observed at 500 µg/ml against HeLa cell line. Minimum inhibition of (7.45%) was shown at an enzyme concentration of 31.25 µg/ml and maximum inhibition (68.28 %) was observed at 500 µg/ml against HepG2 cell line. Minimum inhibition of (4.4%) was shown by enzyme concentration 31.25 µg/ml and maximum inhibition (47.4%) was observed at 500 µg/ml against 3T3L1 cell line. Curcumin at 5µM concentration showed an inhibition of 48.13% against MCF-7 cells, 54.42% against HeLa cells, 64.94% against HepG2 cells and 44.5% against 3T3L1 cell lines.

МЕЛИКИДИ В.Х., ТЮРИНА Д.Г., СЕЛИВАНОВ Д.Г., НОВИКОВА Н.И. ООО «БИОТРОФ», Санкт-Петербург Аннотация: Приведены данные исследования методом газожидкостной хроматомасс-спектрометрии метаболитов, синтезируемых пробиотическими бактериями, входящими в состав кормовой добавки «Профорт®». Проведен опыт в условиях интенсивного промышленного птицеводства по применению кормовой добавки «Профорт®» (50 тыс. голов бройлеров в группе). Среди метаболитов пробиотических штаммов Enterococcus sp. и Bacillus sp. обнаружены такие полезные вещества, как молочная кислота, уксусная, пропионовая и другие короткоцепочечные (летучие) жирные кислоты, активные пептиды. Результаты зоотехнического опыта показали, что при скармливании бройлерам пробиотика «Профорт®» (500 г/т) живая масса при убое в 40 дней была выше контроля на 6,9%, конверсия корма улучшилась на 3,0%, а европейский индекс продуктивности бройлеров - на 5,69%.

A study was undertaken to investigate to occurance of phosphate solubilizing bacteria from rhizosphere soil samples of medicine plants in Cibodas Botanical Garden. 13 soil samples of medicine plants are collected randomly The result shows that 71 isolates of phosphate solubilizing bacteria were isolated, and 10 species of these organism was identified as Azotobacter sp, Bacillus sp, Chromobacterium sp, C.violaceum, Citrobacter sp. , Enterobacter sp., E. liquefaciens. Nitrosomonas sp., Serratia rubidaea, Sphaerotillus natans. Azotobacter sp. And Bacillus sp. Are found in all of soil tested. Conversely, Serratia rubidaea is only in the sample from rhizosphere of Plantago mayor The activity of acid alkaline phosphatase in soil tested ranged from 0.78 – 60,18 ugp nitrophenole/g/h, with the higest values being recorded in soil sample from rhizosphere of “Lavender”.Keywords : phosphate solubilizing bacteria, soil enzyme phosphatase
