BACKGROUND Accurate data on childhood pneumonia aetiology are essential especially from regions where mortality is high, in order to inform case-management guidelines and the potential of prevention strategies such as bacterial conjugate vaccines. Yield from blood culture is low, but lung aspirate culture provides a higher diagnostic yield. We aimed to determine if diagnostic yield could be inc...
Different chemical and physical methods are used for extraction of proteins from bacteria, which are used in variety of fields. But on a large scale, many methods have severe drawbacks. Recently, extraction by means of electroporation showed a great potential to quickly obtain proteins from bacteria. Since many parameters are affecting the yield of extracted proteins, our aim was to investigate...
The relationship between arbuscular mycorrhizal fungi (AMF) and their associated bacteriacan be has great importance for sustainable agriculture especially in the case of highlymycorrhizal plants such as linseed. To evaluate the possible effect of AMF in association withphosphate solubilizing bacteria (PSB) on linseed plants, a 2-yr factorial experiment wasconducted based on a randomized comple...
Auxin produced by plant growth-promoting bacteria (PGPR) in the wheat rhizosphere, can improve plant yield under water deficit stress condition. To investigate this issue, a completely randomized factorial design with three replications was conducted under greenhouse condition at the University of Maragheh, Eastern-Azarbayjan, Iran during 2019. Treatments were two types of growth-promoting bact...
To evaluate the effect of plant growth promoting bacteria (PGPB) on soil physical and chemical indices, yield and its components of two rice cultivars, an experiment was arranged in Rice Researches Institute of Guilan Province during 2009. The experiment design consisted of four randomized complete blocks in a factorial arrangement having 16 treatments in every block. In this research, two fact...
Measurements were made of the yield coefficient during the aerobic metabolism of glucose by a heterogeneous bacterial mixture. Expressed in terms of carbon, the coefficient was approximately 0.48. The value did not vary with initial bacterial densities ranging from 0.4 pg to 40 micrograms of cell carbon per ml and with glucose concentrations ranging from 43 pg to 100 micrograms of carbon per ml...
In the purified bacterial bioluminescent system obtained from Photobacterium jischeri it has been shown that the first step involves the reduction of enzyme by reduced flavin mononucleotide, followed by a combination of reduced enzyme with molecular oxygen (I). The proposed reaction scheme illustrates that aldehyde (RCHO) then reacts with a hypothetical peroxide intermediate to form a complex w...
Golestan province is one of the major regions of wheat production in the country. Azospirillum brasilense، an Azotobacter، acted as resolvent of phosphate and a microorganisms for fixing molecular nitrogen for cooperating with other root crops and grasses in enhancing their growth and development. To investigate the effects of rhizobacteria on yield and yield components of wheat a factorial ex...
