Actinopolyspora egyptensis sp. nov., a new halophilic actinomycete
A halophilic actinomycete, designated HT371T, was isolated from a soil sample collected from the shore of the salty Lake Qaroun, Egypt, and was the subject of a polyphasic study. Analysis of 16S rRNA indicated that the isolate belonged to the genus Actinopolyspora and constituted a separate clade in the Actinopolyspora 16S rRNA gene tree with similarity values of 96.5 and 96.2%...

Bacillus mucilaginosus can capture atmospheric CO2 by carbonic anhydrase
The study mainly demonstrated whether Bacillus mucilaginosus can use atmospheric carbon dioxide (CO2) through the bacteria excreted carbonic anhydrase (CA) capturing atmospheric CO2. It had been proved that CA could reversibly catalyze hydration of CO2. When the bacteria was cultured in the medium containing limestone, Ca2+ concentration and CA activities simultaneously increased with the...

Beneficial effect of eight trigrams boxing exercise on cardiac function and blood indexes of old practitioners
The purpose of this study was to evaluate the effects of the eight trigrams boxing on cardiac function and blood indexes of old practitioners. Subjects, aged 50 years or over, were recruited from a local community. Forty-six participants joined the eight trigrams boxing exercise class five to seven times a week for 1 to 2 h each day for 5 months. Cardiac and blood indexes were measured at the end of each...

The contribution of host cells to dengue virus infectivity
Dengue virus infections remain a significant worldwide public health problem, causing millions of new infections each year. Transmitted by mosquitoes of the Aedes genus, the virus is capable of replicating in a number of different cells of both mosquito and human origin, but the molecular mechanism of infection remains largely unknown. This study sought to determine if the host cell in which a virus...

Antibiotic resistance in Escherichia coli strains isolated from water springs in Al-Ahsa Region
In Saudi Arabia, water resources are largely limited to groundwater, which is used both for drinking and agriculture. There is no surface water except for a few oases and no permanent streams. The contamination of this source possibly through wastewater, agriculture activities and wild birds as well as amphibians and reptiles that have access to wells and springs. Twenty six strains of Escherichia coli,...

Isolation and identification of endophytic bacterium W4 against tomato Botrytis cinerea and antagonistic activity stability
Of the 72 endophytic bacteria isolated from healthy tomato stems and leaves from field-grown plants, the strain W4 gave strongly inhibitory effect on Botrytis cinerea Pers, with the inhibition rate 78% in dual culture assay and 100% using fermentation filtrate diluted 20 times. Based on morphological, physiological and biochemical properties, 16S rDNA gene sequences and Biolog system analysis, the...

Effect of microbial fertilizer on microbial activity and microbial community diversity in the rhizosphere of wheat growing on the Loess Plateau
In this study, the effects of microbial fertilizer on microbial activity and microbial community diversity in the rhizosphere of wheat were investigated in the field conditions. Dehydrogenase activity was measured, bacterial and fungal communities were characterized by BIOLOG analysis. Soil suspensions were applied to BIOLOG ECO and FF plates and average well-color development (AWCD) and richness were...

Effect of salinity on free living - diazotroph and total bacterial populations of two saline soils
Salinization of soil is a serious problem and is increasing steadily in many parts of the world. Recently, soil biotechnology application can improve the potential of saline soils land use in agriculture. The aim of this research was determining the salinity effect on free-living diazotroph and total bacterial populations in two saline soils. Soil samples with salinity of 35 and 70 dS/m selected. The...

Determination of the prevalence of Entamoeba histolytica in human at a private fertilizer company hospital in Pakistan using microscopic technique
Amoebiasis is still a big problem of human civilization at the beginning of 21st century, so every study from this field is valuable. The present study elaborated the prevalence ofEntamoeba histolytica in Pakistani human. During the study, 4712 fecal samples of human were studied by using microscope from October 2008 to January 2010 at a private fertilizer company hospital, Engro Fertilizers,...

Detection of metallo-beta-lactamase (MBL) producing Pseudomonas aeruginosa at a tertiary care hospital in Kashmir
Metallo-beta-lactamases (MBL) producing Pseudomonas aeruginosa strains are responsible for several nosocomial outbreaks in tertiary care centers across the world. It is well known that poor outcome occurs when patients with serious infections due to MBL producing organisms are treated with antibiotics to which the organism is completely resistant. Therefore, detection of these MBL producing P....

Some cellular immune components and C-reactive protein monitoring in female handball players during a competitive period
The aim of the study was to determine the effect of the competitive period training on leukocytes, some leukocyte subgroups and C-reactive protein (CRP) in sportswomen playing in the professional handball league. The average age of the group was 20.6 ± 3.37 years, height average was 163 ± 6.30 cm, weight average was 58.73 ± 4.92 kg. Blood samples were taken before and after the training...

Antibacterial activity of Moringa oleifera and Moringa stenopetala methanol and n-hexane seed extracts on bacteria implicated in water borne diseases
The anti-bacterial activity of methanol and n-hexane extracts of Moringa oleifera andMoringa stenopetala seeds was conducted on 3 bacterial species (Salmonella typhii, Vibrio cholerae and Escherichia coli) which normally cause water borne diseases. The paper disc diffusion method was used with treatments arranged in a completely randomized design and replicated four times. The highest...

A method for the determination of tannase activity based on gallic acid measurement by high performance liquid chromatography (HPLC)
A new high performance liquid chromatography (HPLC) method was developed based on an indirect determination of tannase activity through gallic acid measurement using paracetamol as an internal standard. The separation was performed on a C18 column using a mobile phase consisting of aqueous formic acid solution (1%) and methanol (85:15; v/v) pumped at 1 ml min-1. Samples (10 μl) were injected and...
