Polymerase Chain Reaction-Denaturing Gradient Gel Electrophoresis (PCR-DGGE) Profile of Bacterial Community from Agricultural Soils in Bauchi, North-East Nigeria

引用

Advances in Microbiology 2017年第6期7卷 480-486页

作者： ahmed faruk Umar Fatimah Tahir Ediga Bede Agbo Department of Microbiology Abubakar Tafawa Balewa University Bauchi Nigeria

The population dynamics of bacterial community was investigated in three Agricultural soils, designated as Loamy sand (A), Peaty coarse (B) and Loamy coarse sand (C) in North-East, Nigeria. The soil chemical properties were characterized to fully understand their nature. Metagenomic approach was used to extract soil DNA using the fast DNA Spin Kit extraction technique. The PCR-electrophoresed DNA bands were excised and subjected to a full scale Denaturing Gradient Gel Electrophoresis (DGGE) analysis. DGGE fingerprinting for the PCR-16S rDNA product revealed a diverse profile of complex population of bacterial community in the study area. The study shows that more bacterial community can be fully investigated using molecular techniques rather than traditional culture method. The implication of the results obtained is discussed.

Clinical Isolates of Staphylococcus aureus Show Variation in β-Lactamase Production and Are More Susceptible to Antibiotics Conjugated with β-Lactamase Inhibitors

引用

Open Journal of Medical Microbiology 2016年第4期6卷 143-149页

作者： Uzal Umar Umar ahmed faruk Damoroem M. Tanko Mohammed B. Yerima Department for Biological Sciences Abubakar Tafawa Balewa University Bauchi Nigeria Department of Microbiology Federal University Dutse Dutse Nigeria

β-Lactam antibiotics are a cornerstone in the treatment of bacterial infections on account of its high therapeutic index and selective toxicity—they act by inhibiting the biosynthesis of peptidoglycan, a key component in bacterial cell wall. Ninety (90) clinical specimens obtained from the microbiology unit Specialist Hospital Bauchi were screened for S. aureus, positive isolates were examined for β-Lactamase expression by using two Penicillin G concentrations (5000 IU/ml and 25,000 IU/ml) in acidometric agar technique with phenol red as indicator, and the susceptibility pattern of the isolates to β-Lactam antibiotics was also determined. S. aureus prevalence of 31% (28/90) was obtained, of which 96% (27/28) of strains were β-Lactamase positive in the standard test, while 63% (17/27) were able to hydrolyze penicillin G concentration of 25,000 IU/ml (5X the concentration in the standard test), and a strain was found to be β-Lactamase negative. The resistance to five β-Lactams, ampicillin, cephalexin, amoxicillin, cloxacillin and flucloxaillin, were 100%, 96%, 89%, 74% and 56% respectively. When ampicillin and amoxicillin were conjugated to β-Lactamase inhibitors sulbactam and clavulanic acid respectively the resistance to ampicillin decreased to 21% and to amoxicillin to 15%. The antibiotic susceptibility profile revealed β-Lactamase elaboration to be the major mechanism of resistance to the β-Lactams. β-Lactam utilization as therapeutic option would thus require the search for sensitive irreversible β-Lactamase inhibitors for the β-Lactamase enzymes or agents to block the release of β-Lactamase by strains.

<i>In-Situ</i>Biostimulatory Effect of Selected Organic Wastes on Bacterial Atrazine Biodegradation

Advances in Microbiology 2012年第4期2卷 587-592页

The biostimulatory effect of selected organic wastes on bacterial biodegradation of atrazine (2-chloro-4-ethylamino-6-isopropylamino-1,3,5-triazine) in three agricultural soils in Bauchi state, Nigeria, was carried out. The soil physico-chemical characteristics were investigated to further understand the environmental conditions of the sampling sites. Enrichment technique was used to isolate the atrazine-degrading strains. Mineralization studies were carried out to determine atrazine biodegradation potentials of strains. Polymerase Chain Reaction (PCR) amplification of total nucleic acid of strains revealed several bacterial species based on nucleotide sequence analyses. Biostimulatory effect of selected organic wastes carried out showed minimal to average extent of biodegradation. The highest mean values, in CFU/mL, increase in biomass was recorded in Pseudomonas sp for both Cow dung 16.76 (42.03%) and Chicken droppings 12.32 (38.46%). However, biostimulatory effect using consortia provided more promising results, with 41.51% and 42.08% in Cow dung and Chicken droppings, biomass increase, respectively, in studies conducted. This proves that competition, survival of inoculums, bioavailability of organic amendments and nature of chemical are important factors affecting bioremediation.

AtzABC Catabolic Gene Probe from Novel Atrazine-Degrading Rhodococcus Strain Isolated from a Nigerian Agricultural Soil

引用

Advances in Microbiology 2012年第4期2卷 593-597页

作者： ahmed faruk Umar Fatimah Tahir Michael J.

A batch enrichment technique was used to isolate atrazine-degrading Rhodococcus sp strain from an agricultural land with history of atrazine application in Bauchi state, Northeastern Nigeria. The strain was identified on the basis of physiological, biochemical and 16S r RNA gene sequencing. Growth studies and HPLC analysis showed that the strain has potential of atrazine degradation. An investigation into the catabolic genes Atz ABC, which transform atrazine to cyanuric acid, confirms the chromosomal DNA of strain to harbor BC genes, as compared with the positive control, Rhodococcus jostii RHA1. The strain does not possess the Atz A in all catabolic gene probe carried out. The isolation and characterization of the Rhodococcus sp strain showed that catabolic genes may have evolved from a single origin with widespread global distribution, with possible potential in atrazine bioremediation.

Underwater explosion effects of 60 mm H.E. mortar bomb on a cylindrical concrete structure-PIT

引用

Defence Technology（防务技术） 2019年第1期15卷 65-71页

作者： faruk Razic Burek Miralem Defense Technologies Department University of Sarajevo Faculty of Mechanical Engineering University of Sarajevo Pretis d.d. Igmanska bb

PIT tests are usually performed when a mass distribution of High Explosive(H.E) projectile fragments is required. This paper shows the underwater detonation effects of 60 mm, M90 H.E. mortar bomb filled with Comp. B on cylindrical concrete structure(concrete pipe closed at one end-similar to a PIT test)which is 2 m high(inner height) with inner diameter of also 2 m. Thickness of both wall and bottom of a pipe is 0.35 m. Detailed characteristics of concrete which is used for manufacturing of a pipe are specified. Mortar bomb is submerged directly in to the water(no free airspace around the bomb) with the nose pointing to the bottom of a pipe. Number and mass of fragments after detonation are presented by table and photographs. Fragments of dummy fuze, through which blasting cap was protruded, are collected and reassembled to form a shape of a fuze after detonation where expanding of fuze material due to a detonation products is visualized. After underwater detonation, detonation of the same mortar bomb is performed in an empty pipe and the effects of this kind of detonation are observed. Distance at which fragments generated from submerged mortar bomb will not reach concrete pipes wall is also determined.
