Microbial Inoculants Development for Bioremediation of Gasoline and Diesel Contaminated Soil

Aline Jaime Leal, Edmo Montes Rodrigues, Rita de Cássia Rocha Fernandes, Arnaldo Chaer Borges, Aline Daniela Lopes Júlio, Fernanda de Souza Freitas, Marcos Rogério Tótola
In this study, we describe the development of microbial inoculants for the bioremediation of hydrocarbon-contaminated soils through the enrichment of hydrocarbonoclastic populations in municipal solid waste compost (MSWC). Respirometric analyses were performed along with quantification of total heterotrophic bacteria and ester-linked fatty acid methyl ester (EL-FAME) profiling of the microbial communities o

Vaginal Infections in Pregnant Women at the Bè Hospital in Lomé (Togo) from 2008 to 2013

Koku A. Dakey, Téou Alfa, Yaovi A. Bossa, Komlan Amevo, Amétépé Kpotsra, Yaovi Ameyapoh
Sexually transmitted infections remain a public health problem almost all around the world. Women of childbearing age frequently have vulvovaginitis. The aim of this work is to evaluate the prevalence of the main germs responsible for vaginal infections in pregnant women who have had their vaginal swabs taken at Bè hospital. We conducted a retrospective study between May 2008 and December 2013, on 126 pregnant women in whom a vagi

Response Surface Methodology for the Optimization of Chlorpyrifos-Degrading Conditions by Pseudomonas stutzeri ZH-1

Feng He, Mimi Zhang, Lihong Zhang, Qingping Hu
The removal of pesticides in the environment mainly depends on natural degradation, especially on microbial degradation. Biodegradation has many advantages, such as complete degradation, no secondary pollution, quick effect and wide spectrum. Based on the single-factor experiments and Box-Benhnken design, the effect of four factors on the degradation of chlorpyrifos by P. stutzeri

Detection of Horizontal Transfer of Housekeeping and Hydrocarbons Catabolism Genes in Bacterial Genus with Potential to Application in Bioremediation Process

Edmo Montes Rodrigues, Fernanda de Souza Freitas, Tatiane de Paula Siqueira
In silico analysis can be useful to infer about the horizontal gene transfer (HGT) as well as to deduce about the evolutionary relations of catabolic genes. In this study, we performed the analysis of two housekeeping genes (fabD and rpoD) and two catabolic gene

Sargassum, Gracilaria and Ulva Exhibit Positive Antimicrobial Activity against Human Pathogens

Amrit Kumar Mishra
Bacterial resistance to pharmaceutical drugs is on rise, which emphasizes the need for screening of new drugs from natural resources. Seaweeds from the marine ecosystem are important source of bioactive compounds making them one of the major subjects for screening of various pharmaceutical drugs. So here, we assessed the bacterial growth inhibitory functions of four seaweeds Sargassum wightii

Antimicrobial Activity, Cytotoxicity and Phytochemical Analysis of Sanguinaria canadensis Native to South Dakota

Gitanjali NandaKafle, R. Neil Reese, Robert Oda
A methanolic extract of Sanguinaria canadensis rhizome contains a mixture of benzophenanthridine alkaloids with the major component sanguinarine. American Indians used this rhizome in the treatment of rheumatism, asthma, bronchitis, lung ailments, fever, and warts. Lethal diarrhea in neonatal and post-weaned pigs due to enterotoxigenic Escherchia coli (ETEC) is a major problem among the swine producers of South Dakota region. The increasing resistance of ETEC towards synthetic antibiotics is a m...

Microbiological Quality Assessment of Pupuru and Plantain Flours in an Urban Market in Akure, Ondo State, South Western Nigeria

Christiana Eleojo Aruwa, Omolola Ogundare
Cassava and plantain flours are commonly used in preparation of a variety of food delicacies in South Western Nigeria. These are however sold in open air markets, and are scarcely required to be subjected to safety checks by food safety authorities. A study was designed to assess the microbiological food quality of cassava (pupuru) and plantain flour purchased from different vendors at Oja-Oba, Akure, Ondo state, as well as the an

Adenoviruses Type D in Patients with Respiratory Tract Infection Symptoms

Naeme Javid, Abdolvahab Moradi, Alireza Mohebbi, Majid Talkhabifard, Mishar Kelishadi, Alijan Tabarraei
Different Human Adenoviruses (HAdV) serotypes are associated with epidemic respiratory infections. The aim of this study was to detect HAdV from patients with respiratory symptoms and typing virus circulating in North of IRAN. Four hundred nasopharyngeal aspirate samples were obtained from patients with respiratory symptoms. Clinical data were collected. After DNA extraction, Polymerase Chain Reaction (PCR) was done for conserved

The Effect of Different Wavelength of Light for Microbial Fuel Cell with an Anode of Rhodopseudomonas faecalis (PSB-B)

Guang Rong, Qingping Hu
A microbial fuel cell (MFC) with an algae-assisted cathode is a low-cost and sustainable way to provide the oxygen for the oxygen reduction reaction. The anode was with anaerobic microorganism, a kind of photosynthetic bacteria (PSB-B). An algae bioreactor was connected to cathode microbial fuel cells to increase power generation by supplying more oxygen to cathode electrode. In this study, we

Enhancing the NaCl Tolerance Potential of Wheat on Root Morphology and Osmoregulation Substance by Exogenous Application of Bacillus subtilis QM3

Ruiqing Liu, Caifang Wen, Zhifang Zhao, Guang Rong, Jianguo Xu, Qingping Hu
Bacillus subtilis QM3 is a strain of antagonistic strains which have biological control function. Salinity is the most important limiting plant factor for agriculture development and growth changes in wheat. The present study was carried out to test tolerance involved in salt stress alleviation in wheat (
