Alkaline cellulase produced by a newly isolated thermophilic Aneurinibacillus thermoaerophilus WBS2 from hot spring, India

  A thermophilic bacterium Aneurinibacillus thermoaerophilus WBS2 producing extracellular thermophilic cellulases was isolated from hot spring in India. Till date there is no report in literature about thermophilic cellulases produced by A. thermoaerophilus and optimization of nutritional factors for increasing cellulases yield. In order to enhance cellulase production, various fermentation...

Degradation of weathered crude oil (Escravos Light) by bacterial strains from hydrocarbons-polluted site

  Two hydrocarbon degrading Gram-negative bacteria isolated from hydrocarbon polluted power plant soil in Lagos, Nigeria, were studied for their degradation potentials on weathered crude oil (Escravos Blend). These bacteria isolates were identified asEnterobacter cloacae strain LG1 and Burkholderia cepacia strain LG2. The highest population density for LG1 was 2.07 x 107 cfu/ml, while...

Early prediction of cardiovascular diseases, a lifestyle disorder, in software people in south India using high sensitive c reactive protein (hsCRP)

  The study was aimed to find out the incidence of cardiovascular diseases in young software professionals. Coronary artery block or arteriosclerosis was considered to be a form of inflammation. High sensitive C - reactive protein (hsCRP) is considered to be one of the sensitive markers of systemic inflammation, which has also been associated with an increased risk of cardiovascular disease. Software...

Biocontrol potential of a Pseudomonas aeruginosa strain against Bactrocera oleae

  A formulation was developed from the metabolite(s) of Pseudomonas aeruginosa (IL5) and tested against 3rd instar larvae of the olive fruit fly Bactrocera oleae, the most serious pest on olive cultivations in the world. In this study, we have isolated 115 bacterial strains from various ecological niches from the soil, water, dead insects and infested olives and tested their...

Response of cowpea lines to low Phosphorus tolerance and response to external application of P

  Low availability of phosphorus (P) is a major constraint to crop production in Sahel and Sudan Savanna of West Africa, and efforts are being made to identify cowpea genotypes with tolerance to low P and greater P use efficiency. Arbuscular mycorrhizal fungi (AMF) enhance P uptake in low P soil. Cowpea breeding lines (200) were examined at 3 P levels (0P, 90 kg P ha-1 as Rock Phosphate and 30 kg P...

Polymerase chain reaction (PCR) diagnosis of human brucellosis (l7/l12 and 16srRNA genes) compared with immunocapture-agglutination test (brucellacapt) and common serological tests

  Diagnosis of the human brucellosis mainly depends on blood culture and serological tests. The most commonly used tests are the serum agglutination test (SAT), Coombs anti-Brucella, and Rose Bengal tests. New diagnostic tests such as immunocapture-agglutination test (Brucellacapt) and polymerase chain reaction (PCR) have been used. This study aims to compare PCR method by...

Chemical composition and antimicrobial activities of essential oils (EO) extracted from leaves of Lippia rugosa A. Chev against foods pathogenic and adulterated microorganisms

  Alternative natural additives are needed in order to guarantee food safety in preservation against foods pathogenic and adulterated microorganisms. Aromatic plants are traditionally employed for seasoning and prolongation of shelf life of food. The majority of their properties are due to the essential oils produced by their secondary metabolism. Great interest is given to these oils by the industry and...

Construction of suppression subtractive hybridization library from Cirsium setosum (Willd.) MB under glyphosate stress

  The mRNA isolated from Cirsium setosum (Willd.) MB before treatment with glyphosate was used as a ‘’driver’’, and the mRNAs isolated from C. setosum (Willd.) MB after treatment with glyphosate at different times were used as ‘’testers’’. One suppression subtractive hybridization (SSH) library of C. setosum (Willd.) MB...

Microencapsulation of Lactobacillus casei with calcium alginate-resistant starch and evaluation of survival and sensory properties in cream-filled cake

  Lactobacillus casei ATCC 39392 was encapsulated with calcium alginate-resistant starch via emulsion technique. The probiotics bacteria were inoculated to cream-filled cake in their free and microencapsulated forms. The survival of free and microencapsulated bacteria and pH changes in cream-filled cake were monitored during 4 weeks storage at 4 and 25°C. The morphology and size of microcapsules...

Prevalence of SHV β-lactamases in Escherichia coli

    Resistance to β-lactam antibiotics by Gram-negative bacteria, especially Escherichia coli, is a major public health issue worldwide, and is often caused by the production of β-lactamase enzymes. Specifically, extended-spectrum β-lactamases (ESBLs), which cannot be diagnosed by phenotypic tests recommended by the Clinical and Laboratory Standards Institute (CLSI), are often produced....
