Bacterial Diversity in Different Positions in the Iraqi Marine Area Shubbar Jaafar, Asaad Al-Taee, F. N. Al-Kanany Baghdad Science Journal, 2023 : Microorganisms establish both structural and functional construction in the marine environment, despite scientific advances, the identification of marine bacterial species is still considered as a common challenge in microbiology. Nevertheless, the present study aims to make an effort, although it seems modest, but it could establish a basis for studying the bacterial diversity in the Iraqi marine area, because of what this aspect entails of the poverty of studies related to this aspect in the studied area. The current results show the marine studied area are classified within worming area, where the average temperature ranged from 23.17 to 26.17 ºC. The recorded number of bacteria was increased with temperature increasing (0.210, 0.250, 0.305, 0.517, 0.553 and 0.625) through the studied period (January, February, March, April, May and June) respectively. The results showed that the identified bacteria were related to three bacterial phyla(Firmicutes, Proteobacteria, and Actinobacteria),with the clear superiority to the phyla (Firmicutes).The most occurrence bacterial genera were( Staphylococcus lentus, Vibrio parahaemolyticus, Vibrio alginolyticus, Sphingomonus paucimobilis and Aeromonas hydrophila/caviae), which have different percentage of frequency ,(50,40,60,30 and 20%) respectively. The present discoveries provide initial evidence on the bacterial diversity in the Iraqi marine waters. Further studies are necessary to make a more comprehensive image of bacterial diversity within these marine regions.
Combined Efficacy of Lawsonia inermis and Myrtus communis Extract as a Potential Factor in Bacterial Treatment to Hospital Wastewater, Iraq Dhay J. Edan, Munther Abduljaleel Muhammad-Ali, Raghad Shubbar Jaafar Iop Conference Series Earth and Environmental Science, 2023 The current study aimed to use biological treatment using plant extracts; extracted from some locally available plants: Lawsonia inermis (Henna), and Myrtus communis (Yass), against pathogenic bacteria isolated from heavy water in hospitals that do not have treatment plants. The two studied plants were extracted using two different solvents (water and alcohol). Diagnosis of these extracted using Gas chromatography (GC-MS) showed that the alcoholic extraction led to a higher percentage of effective phenolic compounds than the aqueous extract. Sewage water was used to isolate bacteria and according to the morphological, and biochemical, confirmed by using the vitke II instrument; six types of pathogenic bacteria were identified (Staphylococcus lentus, Staphylococcus xylosus Sphingomonas paucimobilis, Escherichia coli, klebsiella oxytoca, Serratia ficaria). The two Alcoholic plant extracted showed excellent antibacterial activity against all pathogenic bacteria than the water extracted as revealed by the diameter of the inhibition zone.
The Potential Role of Soil Bacteria as an Indicator of Heavy Metal Pollution in Southern, Iraq R. Jaafar Baghdad Science Journal, 2022 The present study was performed to spotlight the potential role of soil bacteria in the Al-Rumaila oil field as a bioindicator of heavy metals pollution. For this purpose, nine soil samples were collected from different sites, with 20cm depth, to assess the pollution status depending on the total and available concentrations of heavy metals. The result indicates pollution of the studied soils with the following metals: Cd, Cu, Fe, Zn, and Pb. The mean of total concentration for all studied metals was higher than the allowed maximum limit based on the international limit:(3.394, 3.994, 39.993, 8844.979,150.372, and 103.347 μg/g), respectively. While measuring the total Metal concentration is important in determining the degree of pollution in the environment; it cannot be depended to determine their impact on the living organisms. In the present study the means of available concentration of studied metals were as follows: 0.015, 0.787, 0.021, 0.515, and4.304 μg/g. respectively, which were lower than their total concentration. Different types of bacterial genera (Serratia marcescens, Sphingomonas paucimobilis, Bacillus subtilis, Pseudomonas aeruginosa, and Staphylococcus lentus) were isolated from the same soil. And broadcasts through the results their presence in all studied soils. Therefore, the isolated bacteria play a significant role as an indicator of metal pollution in the soil, which was proved through the result of the Minimum inhibitor concentration (MIC), which indicated a high tolerance ability towered these metals.
How to link: Plasmid Curing and Lead Tolerance Ability of Pediococcus pentosaceus Fadhil Neamah Al-Kanany, Raghad Shubbar Jaafar Journal of Tropical Biodiversity and Biotechnology, 2022 Pediococcus pentosaceus has a high level of resistance to heavy metals, making it one of the biological alternatives for dealing with heavy metal contamination in the environment. The current study sought to identify the genetic factors responsible for this ability by curing the plasmid of these bacteria using various curing agents (Acridine orange and Sodium Dodecyl Sulfate). The findings demonstrate that both curing agents had perfect curing ability. The bacteria were able to tolerate a wide range of Lead concentrations (50-2000 ppm). This capacity was reduced when the plasmid was removed, but it did not disappear, implying additional resistance genes on the chromosomes. The antibiotic susceptibility observations supported the significance of plasmid genes in lead resistance ability, the findings revealed differences in the pattern of antibiotic resistance between wild and cure plasmid bacteria, the wild one had different antibiotic MIC values for Nitrofurantoin and Trimethoprim/Sulfamethoxazole (<=16 and <=10 µg/ml) respectively), on the other hand for the same antibiotics, the MIC results for plasmid-cured bacteria were 64 and 80 g/ml. Based on the findings, we can conclude that plasmid genes play a significant role in Pediococcus pentosaceus to resist lead, and there is a strong correlation between antibiotic resistance and lead resistance.
Microbes as bioindicators for contamination of Shatt Al-Arab Sediments in Basrah, Iraq Maha K. Al-Mishrey, Raghad Shubbar Jaafar, Mustafa A. Al-Dossary Journal of Pure and Applied Microbiology, 2021 Shatt Al-Arab River in Basrah, Iraq represents an important source of fresh water so the current study aimed to determine the extent of pollution of the Shatt al-Arab River with some heavy metals and hydrocarbons by measuring their concentrations in sediment samples collected from different stations along the river, as well as the adoption of biomarkers represented by bacteria and fungi in determining the extents of such pollution. The results indicate that the river is contaminated with the following metals:: Ni, Cr, Zn, Pb, Cu and Cd. The total mean concentrations of heavy metals in the exchangeable part were high with 55.23, 53.76, 40.52, 33.84, 32.70 and 14.88 µg/g, respectively. The results also indicated a high concentration of hydrocarbons where the total mean was 28.52 µg/g. Bacteria and fungi represent vital indicators of heavy metals and hydrocarbons pollution in the environment. Different types of bacteria (Sphingomonas paucimobilis, Bacillus subtilis, Pseudomonas aeruginosa, Streptococcus thoraltensis, Staphylococcus lentus, Leuconostoc cremoris and Leuconostoc mesenteroides) and fungi (Aspergillus terreus, Aspergillus fumigatus, Aspergillus niger, Curvularia sp., Eurotium cristatus, Talaromyces flavus, Mucor sp., Rhizopus sp., Trichoderma sp., Dichotomomyces cejpii, and Penicillium spp.) have been isolated from the same sediment. Isolated of specific genera from bacteria and fungi like these isolated in the present study from the sediment of all studied stations reinforces the rest of the results recorded during the current study and confirms the pollution of the river with the studied pollutants.
