英國OXOID 高質量培養(yǎng)基

----Oxoid于1924年成立，現(xiàn)屬于知名的Thermo Fisher Scientific集團一員，目前為領先全球的微生物培養(yǎng)基制造商與診斷試劑銷售商。公司總部位于英國貝星斯托克(Basingstoke)，產品銷售遍及歐盟各國、美洲與澳洲，另外也委托世界各地專業(yè)的微生物產品代理商經營國際Oxoid事業(yè)。Oxoid產品范圍闊及與疾病、微生物診斷相關的臨床檢驗科學、基礎學術研究與工業(yè)生產領域。Oxoid主要產品線包括有:1. 培養(yǎng)基 (Culture Media & Supplements)2. 產色素培養(yǎng)基 (Chromogenic media)3. 厭氧培養(yǎng)系統(tǒng) (Atmosphere Generation)4. 微生物藥敏分析 (Antimicrobial Susceptibility Testing)5. 診斷試劑 (Diagnostic reagents)

馬鈴薯葡萄糖瓊脂|Potato Dextrose Agar用途:用于分離皮膚真菌、其它霉菌和酵母的酸性培養(yǎng)基。也可用與EP/USP/JP 協(xié)同的微生物限度檢查法中黑曲霉的準備500g 可以配制12.8 升培養(yǎng)基DirectionsSuspend 39g in 1 litre of water (purified as requested). Bring to the boil to dissolve completely. Sterilise by autoclaving at 121°C for 15 minutes. Mix well before pouring.In order to suppress bacterial growth it is sometimes desirable to acidify the medium to pH 3.5. This can be done by adding 1ml of Lactic Acid 10% SR0021 to each 100ml of sterilised medium at 50°C. The medium must not be heated after the addition of the acid; this would result in hydrolysis of the agar and destroy its gelling properties.DescriptionFoodA suitable medium for the isolation and count of yeasts and moulds in dairy products1 or those occurring on the surface of fresh meats, cured meats and sausage products and other foods 2. This medium is suitable for the detection and enumeration of heat resistant moulds in thermally processed fruits and fruit products 2.Work carried out in cooperation with CSIRO Melbourne had shown that the minerals present in agar could influence the pigment formation of certain fungi. Where pigment production is a critical part of the identification of the fungus it is clearly important to stabilise this characteristic. The agar used in Potato Dextrose Agar is carefully screened to ensure correct pigment production by fungi such as Fusaria spp.PharmaA suitable medium for the preparation of Aspergillus niger. Potato Dextrose Agar conforms to the parameters of the harmonised Microbial Limit Tests from EP/USP/JP (enumeration test)3,4,5,.Additional information about this and other products in our harmonised range can be obtained by downloading our Harmonised Culture Media Portfolio.TechniqueFoodAfter sterilising the reconstituted medium adjust the reaction to pH 3.5 by adding 1ml of Lactic Acid 10% (SR0021) to each 100ml of medium at 50°C. Do not reheat after acidification.Prepare dilute emulsions or suspensions of the product to be tested, make pour-plates in the usual manner, and incubate for 5 days at 21°C. Count the number of yeast and mould colonies.If a non-selective medium is required, it is suggested that Potato Dextrose Agar may be used without added acid or, alternatively, one may use a general purpose mycological medium such as Malt Extract Agar (CM0059).PharmaGrow Aspergillus niger on Potato Dextrose Agar (CM0139) at 20-25°C for 5-7 days or until good sporulation is achieved.Storage conditions and Shelf lifeStore the dehydrated medium at 10-30°C and use before the expiry date on the label.Store the prepared medium at 2-8°C.AppearanceDehydrated medium: Off-white, free-flowing powderPrepared medium: Light straw coloured gel

保存條件：2-8°C
