Use of 3S technology as a tool for endangered vegetation area assessment in Togo

The main objective of research was to use 3S technology coupled to traditional method of vegetation sampling to assess the vegetation dynamic in Northern Togo. The remote sensed data of three different years (1987, 2000 and 2007) were used to evaluate the land use change by employing the normalized difference vegetation index (NDVI) algorithm, Iso-Data unsupervised classification and change detection method set by...

Comparative association of species of Culicinae (Diptera) at various altitudes in Republic of Korea

Korean peninsula and south western region (Jeju Island) are heavily covered with natural vegetation and represented by mountains, valleys and streams. This study aims to detect mosquito species from subfamily Culicinae and their breeding places at altitudes 26 to 1345 m. The larvae and adult samples were collected during six months period from June to November 2009 by using plastic pipette and BG Sentinal. 6 genera and...

Genistein inhibits expression of matrix metalloproteinases-2 (MMP-2) in premature ovarian failure (POF) rats induced with cisplatin intraperitoneal injection

Matrix metalloproteinases (MMPs) play a pivotal role in ovary disease by degrading multiple elements of the extracellular matrix (ECM). Therefore, the inhibition of MMPs has been suggested to be a promising therapeutic strategy for premature ovarian failure(POF). Genistein, the primary isoflavone in legumes, has a well known weak estrogenic effect by binding to estrogen receptors, and widely used in the...

A descriptive study of keratinophilic fungal flora of animal and bird habitat, Jaipur, Rajasthan

Keratinophilic fungi occur abundantly in the superficial soil layer of landfills and their surrounding. Forty seven soil samples of animal (37 samples) and bird (10 samples) habitats from different localities of Jaipur District were collected for the estimation of keratinophilic fungi using the hair baiting technique. Seventy five isolates belonging to 14 genera and 20 species were reported. Soil pH range varies from...

Molecular analysis and in vitro susceptibility profiling of some clinically important Candida spp. to the common antifungal drugs

This study aimed to determine the in vitro susceptibility profiles of a group of Candidaspecies to some of the common antifungal drugs in clinical use. Thirty nine Candidaisolates were collected from the blood of immunocompromised patients with cancer. Isolates were cultivated on CHROMagar, identified using API20C kit and the ID was confirmed by polymerase chain reaction-restriction fragment length...

High prevalence of atypical class 1 integrons and class 2 integrons in multi-drug resistance Shigella flexneri isolated from China

Shigella flexneri is an important cause of bacterial dysentery in the developing world. Treatment with most widely used and inexpensive antimicrobial drugs became limited due to globally emerging antimicrobial resistance. Integron-associated antibiotic resistance was observed in S. flexneri. This study described the antimicrobial susceptibility and the characteristic of classes 1 and 2 integrons in S....

Biodegradation of mineral oil by bacterial strains isolated from contaminated soils

Potential mineral oil degrading bacterial isolates (Pseudomonas putida, Rhodococcus erythroplolis and Bacillus thermoleovorans) were studied from the contaminated soils.The bacterial populations of these polluted soils were 5.25 × 105, 1.76 × 106 and 5.11 × 105 CFU/ml with three different colony types of bacterial strains, respectively. Microbial population diversity...

Comparison of SYBR Green and turbidimetry methods for loop mediated isothermal amplification (LAMP) product detection in diagnosis of hepatitis B virus (HBV)

Hepatitis B virus (HBV) is one of the leading causes of hepatocellular carcinoma and liver diseases. The HBV serological and molecular detection methods have some limitations; therefore, use of these methods is not feasible in many diagnosis centers. In this study, SYBR Green was compared with spectrophotometry for turbidity assay for final detection of LAMP reaction product in diagnosis of HBV. Two hundred HBsAg...

Diversity analysis of bacteria in the latter ripening of Pixian soybean paste fermentation based on 16S rDNA analysis

The biodiversity of bacteria inhabited in the latter ripe fermentation of Chinese traditional Pixian soybean paste was investigated based on bacterial 16S rDNA culture independent method. A total of 102 clones were recovered and belonged into Pseudomonadaceaefamily (3%), Enterobacteriaceae family (14%), Lactobacillaceae family (3%), Bacillaceaefamily (44%), Staphyloccaceae family...

Enzymatic potential and characterization of poly-extremophilic bacteria isolated from saline and salt-affected soils in Egypt

Fourteen poly-extremophilic bacterial strains were isolated from saline and salt-affected soils in Egypt. Isolation of the strains was done after incubation at 55°C on two different agar media supplemented with 10% NaCl and adjusted at pH 10 (thermohaloalkali philic/tolerant). The isolated extreme bacterial strains were screened for their enzymatic potential. They showed high amylolytic and proteolytic activities...

Improvement of fermentation process of bifidobacteria soybean yoghurt: A uniform design approach

This study aimed at producing soybean yoghurt containing bifidobacterium by temperature shifted fermentation process, and to increase the viable counts of bifidobacterium in the soybean yoghurt. First, parallel test was used to investigate the amount of carbon source of high fructose corn syrup. Secondly, using the Mathematic 7.01 software program, the relationships between the viable counts of bifidobacterium and...

Relationship between microbial community and soil properties during natural succession of forest land

Recently, there has been increasing research focus on microorganism community structure in secondary forest succession. This study aimed at analyzing the community diversity of bacteria and fungi in the forest in six different ecological regions of Changbai Mountains in Jilin Province of China, by terminal restriction fragment length polymorphisms (T-RFLP). Results show that the fungal and bacterial diversity differed...

Optimization of fermentative production of poly-(γ-glutamic acid) by a newly isolated Bacillus subtilis BABRC-11

A newly isolated poly-(γ-glutamic acid) (γ-PGA)-producing strain BABRC-11 was identified as Bacillus subtilis based on its morphological and physiological characteristics as well as 16S rDNA sequence. The fermentation medium for the production of γ-PGA by B. subtilisBABRC-11 was optimized statistically. The parameters significantly affecting γ-PGA production were found to be sodium...
