The present study was conducted to evaluate the effect of Poly-3-Hydroxy butyrate against the sporulation of oocyst of E. tenella. In this study four different doses of PHB which was extracted from the Bacillus subtilis culture, 10, 20, 50and 100mg were used with 2.5% potassium dichromate as positive control and distilled water as negative control. The experiment was carried out in 24 well plates.

The potassium dichromate oxidation method used in determination of alcohols in fermentation has two major disadvantages. This method cannot be used to determine alcohols in raw fermentation broth samples, which often contain various reducing sugars. The method is not environment friendly due to the carcinogenicity of Cr (VI) used.

This study was aimed to determine the prevalence of intestinal helminth parasites of local chicken (Gallus gallus domesticus) from Lalitpur district, Nepal. It was carried out from February 2014 to March 2015. A total of 125 samples (93 alimentary canals of freshly killed chicken and 32 stool samples from ground and fowl runs) were collected. Out of 93 alimentary canals 17 were collected from free range chicken and 76 were from slaughtered house i.e. from poultry farm chicken. The faecal samples were collected in the sterile vials containing 2.5 percent potassium dichromate.

Nowadays, heavy metal pollution is an urgent problem in the world including Vietnam. An analytical approach is very important to identify, assess and forecast environmental risks from toxic components, in which ecotoxicology is considered to be the optimal tool. We conducted a study on M. micrura in order to contribute the creation of a biological basis for the use of zooplankton as an early warning of the risk of water pollution. The results showed that M. micrura was isolated from 29/3 Park Lake, Da Nang City, central Vietnam. The acute toxicity test of potassium dichromate on M.

Hiện nay, ô nhiễm kim loại nặng đang là vấn đề rất có tính chất toàn cầu. Cần có phương pháp phân tích để xác định, đánh giá và dự báo các rủi ro môi trường từ các thành phần chất độc, trong đó phương pháp độc học sinh thái được xem là công cụ tối ưu. Các tác giả đã thực hiện nghiên cứu độc học trên M. micrura nhằm góp phần tạo cơ sở sinh học trong việc sử dụng động vật phù du làm sinh vật cảnh báo sớm nguy cơ ô nhiễm nguồn nước.

A strain of Pseudomonas sp. C-171 capable of tolerating hexavalent chromium (Cr+6) up to 2000 ppm as potassium dichromate was isolated from domestic sewage. The Cr+6 reduction was checked by growing the isolated strain in a medium containing potassium dichromate as Cr+6 source.

A simply and accurate analytical method was developed to determination the carbon content in silica-supported materials. The principle of this method was to oxidize sample by a strong oxidant like potassium dichromate to produce carbon dioxide and this gas is absorbed into an alkaline solution for subsequent titration.
