Both for epidemiologic studies and for diagnostic testing, there is a need for effective, economical, and readily available selective media for the culture of Clostridium difficile. We have developed a reduced-cost substitute for cycloserine-cefoxitin-fructose agar (CCFA), which is an effective but expensive selective medium for C. difficile. The modified medium, called C. difficile brucella ag...

Production of indigenous isolate Bacillus thuringiensis sv2 (Bt sv2) was checked on conventional and nonconventional carbon and nitrogen sources in shake flasks. The effects on the production of biomass, toxin production, and spore formation capability of mosquito toxic strain were determined. Toxicity differs within the same strain depending on the growth medium. Bt sv2 produced with pigeon pe...

Landfills generate leachate that contains elevated concentration of contaminants and is hazardous to human health and the ecosystem. In this study, the mixture of granular activated carbon and cockle shells was investigated for remediation of COD and ammonia from stabilized landfill leachate. All adsorbent media were sieved to a particle size between 2.00 and 3.35 mm. The optimum mixing ratio, ...

Agricultural wastes are available in large volumes at low cost and have been considered promising sustainable resources for the synthesis of many biopolymers. The agro-industrial waste products such as paddy straw, sugarcane bagasse, potato peel can serve economical nutritional sources cultivation fungi. Our studies revealed that growth media supplemented with @ 1% straw +1% glucose (w/v) yield...

the inventive step requirement which purportly secure the growth ofinnovation and resulting industrial and economic development, despite ofcontaining some benefits, always faced with the challenges that in somecases ,such challenges are in opposition with the bases of patents system andindicates that ,patents system do not beneficial always. analysis of saidchallenges studied upon the economica...

the most common pathogenic agent in sunflower is sclerotinia sclerotiorum which in some cases can be successfully controlled by some antagonistic bacteria. environmental factors such as carbon sources are effective on antagonistic strains but application of pure carbohydrates for mass production of these agents is expensive. so in most cases agricultural and industrial residues (such as molasse...

soilless media have different physical properties. change in air space of mix substrate can cause change in fertigation management and plant growth and yield. physical properties (water holding capacity, effective air-filled pore space, effective pore space) of 50 mixed substrates were measured to evaluate the effect of air-filled pore space on growth of tomato transplant and it's water us...

Three media formulated from molasses and cornsteep liquor and another media based on the basal medium formulation of IPS-82 were assessed for the growth and production of insecticidal properties of B. thuringiensis H-14 .• Bacterial powders prepared from the broth cultures were assayed against the larvae of Culex pipiens and Anopheles stephensi. A standard powder of IPS-82 was included in ...

microbial cells are producers of natural polymers present in plant cells. production of pullulan (an extracellular microbial polysaccharide) by aureobasidium pullularia pullulans (p. pullulans) was studied under fermentation conditions, and kinetic parameters were determined. pullulan formation obeyed a growth and non-growth associated term. phb (polyhydroxybutyrates) an intracellular biopolyme...
