| 7 | Biosurfactants from lactic acid bacteria:A critical review on production,extraction,structural characterization and food application显示文摘Biosurfactants are structurally diverse classes of amphiphilic molecules derived from microorganisms.They have various properties such as surface,emulsification,antibacterial,anti-adhesive,anti-biofilm,antioxidant activity that can be used in many industrial fields.The interest in these molecules compared to their synthetic counterparts is due to their biodegradability,low toxicity,structural diversity,and stability over a wide range of pH,temperature,and salinity.Among biosurfactants,those derived from lactic acid bacteria(LAB)attracted attention nowadays due to the GRAS(Generally recognized as safe)status of these microorganisms.Biosurfactants production by LAB strains has been documented in several investigations,and they deal with the functionality and chemical nature of biosurfactants.LAB biosurfactants were mainly a complex mixture of proteinaceous compounds,glycolipids,glycoproteins,or glycolipopeptides.There are only a few studies reporting on the elucidation of the structure of LAB biosurfactants.Generally,biosurfactants’production process includes several unit operations starting from screening methods to the characterization of the biosurfactant compound.This review highlights the different techniques used in the screening of biosurfactants production by LAB,their extraction and purification processes,and their structural characterization and application in the food industry. | Hippolyte T.Mouafo Alphonse T.Sokamte Augustin Mbawala Robert Ndjouenkeu Somashekar Devappa | 2022 | Food Bioscience2022，46，2： | 1 |

| 11 | 双胎妊娠中与反复发生的母亲菌血症相关的胎盘脓肿的诊断显示文摘BACKGROUND: Placental abscess formation is rarely recognized prenatally. We present a case detected ultrasonographically that developed from a central line infection and caused recurrent maternal bacteremia. CASE: A young woman with a 21-week twin gestation presented with recurrent fevers. She had received treatment for bacteremia due to Serratia marcescens. The initial source of the infection was a peripherally inserted central catheter line placed in the first trimester for hyperemesis gravidarum. Fevers continued throughout the second course of antibiotics. An abscess seen sonographically in twin A’s placenta was aspirated using a spinal needle, revealing Serratia bacteria. Aspiration was performed at 22 weeks of gestation. Amniotic fluid samples obtained from both sacs were negative for infection. Over 4 weeks, the abscess enlarged and she was delivered. Twin A died of sepsis and twin B had a relatively favorable neonatal course. CONCLUSION: Prenatal diagnosis of placental abscess presents a difficult management dilemma. Traditional amniotic fluid studies did not predict the poor outcome of the affected fetus. | Meirowitz N.B. Fleischer A. Powers M. Hippolyte F. 张旸 | 2006 | 世界核心医学期刊文摘(妇产科学分册)2006，0，10： | 0 |
| 12 | Studying the Impact of Anions Pre-generated Iron Corrosion Products on the Efficiency of Contaminant Removal in Fe0/H2O Systems显示文摘The effects of Fe0 pre-corrosion by water,bicarbonate,chloride,phosphate and sulfate on the efficiency of Fe0 systems for water treatment were investigated.Batch experiments were conducted for a total duration of 72 days with MB(Methylene Blue)and MO(Methyl Orange).The efficiency of used Fe0 was assessed by characterizing the extent of MB and MO discoloration,pH variation and amount of iron released as a function of anion type.Before dye addition,used Fe0 in Fe0/sand and 100%Fe0 systems was allowed to equilibrate with H2O or the anionic solution for 0 to 44 days.Pre-corrosion has low impact on MB discoloration but has negative impact on MO discoloration.Relative to the reference system(anion free system,H2O),all the tested anions enhanced MB discoloration but decreased that of MO.HPO4 2-and HCO3-severely affects MO discoloration.The pH of the medium governs the discoloration with MB performing better at higher pH and MO doing same at lower pH.For MB,Fe0/sand system shows higher efficiency than 100%Fe0 system.But the two systems show similar efficiency for MO.Results will help in the design and functioning of Fe0 based filtration systems and other water treatment designs using Fe0. | Cornelius Tsamo Djibrine Sali Meali Hippolyte Todou Assaouka | 2018 | Journal of Environmental Science and Engineering(B)2018，7，1： | 0 |
| 13 | Microbial Assessment and Antibiotic Susceptibility Profile of Bacterial Fish Isolates in an Aquaculture Production Site in Mefou Afamba Division of Cameroon显示文摘The practice of integrated fish farming and the use of local fish meal and manure for fish feeding in Cameroon constitute potential sources of resistant pathogenic bacteria in the fish pond environment.Therefore,a periodical and constant monitoring of the microbiological quality of fish pond is imperative.This study was to assess the microbial contamination of Mfou aquaculture production site and evaluate the antibiotic resistance profile of bacterial fish isolates.Samples of pond water(n=36),sediment(n=36),fishmeal(n=12)and African catfish(Clarias gariepinus),kanga(Heterotis niloticus)and Nile Tilapia(Oreochromis niloticus)(n=36,each)were collected to determine TVAC(Total Viable Aerobic Bacterial Count),FC(Fungal Count),SAC(Staphylococcus aureus count),TCC(Total Coliform Count)and FCC(Feacal Coliform Count).The fish skin isolates of S.aureus,Enterobacter sakazakii,Citrobacter freundii,Serratia fonticola,Klebsiella oxytoca,Proteus spp.,Aeromonas hydrophila,Kluyvera spp.,Moraxella spp.,Pasteurella multocida and Pseudomonas fluorescens were tested against penicillin G(10μg),chloramphenicol(30μg),sulfamethoxazole/trimethoprim(25μg),erythromycin(15μg),tetracycline(30μg),using the disk diffusion method.Results reveal a heavy contamination of fish farms with microbial load above the recommended limits.Our study indicates that fish ponds are sources of zoonotic pathogens underlining their epidemiological and clinical relevance.All bacterial isolates were multiresistant with a multiple antibiotic resistance index above 0.2.These data raise concern about the microbial contamination of aquaculture and associated public health risks in Cameroon. | Judith Julie Takadong Tsafack Dimitri Alex Kamgain Tchuenchieu Hippolyte Tene Mouafo Manuela Annick Bengue Baomog Jorelle Jeanne Bimem Adjele Evrard Koupestchop Medjo Imelda Lucresse Nouteza Djuikoo Bridget Tata Ndakoh Chelea Matchawe James Sasanya Gabriel Nama Medoua | 2021 | Journal of Environmental Science and Engineering(B)2021，10，1： | 0 |
| 14 | Ageing evaluation of cable insulations subjected to radiation ageing:Application of principal component analyses to Fourier Transform Infra-Red and dielectric spectroscopy显示文摘The evolution of properties of crosslinked polyethylene(XLPE)-based insulating mate-rials under radio-chemical ageing conditions is presented and discussed.In total,seven different polymer compounds were tested,characterised by an increasing quantity of additives,for example,antioxidants(AOs)and fillers as flame retardants.Samples were analysed using different testing techniques,that is,Fourier Transform Infra-Red and dielectric spectroscopy.This allowed a broad characterisation of the polymer,bringing to good correlations between the arising of new chemical groups caused by ageing and the modifications on the complex permittivity.Phenol-based AOs are found to be the most efficient in terms of protection against oxidation.On the contrary,flame retardants are concluded not to have any impact on the material ageing.Acquired data were then treated using the principal component analysis.The data treatment successfully distinguished the material composition(with and without additives)and the ageing environments.The results confirm the relevance of this analysis in understanding the impact of irradiation on the chemical and functional properties of the polymer materials studied. | Simone Vincenzo Suraci Sandrine Amat Lea Hippolyte Astrid Malechaux Davide Fabiani Claire Le Gall Océane Juan Nathalie Dupuy | 2022 | High Voltage2022，7，4： | 0 |
| 15 | Morphological characterization and habitat suitability modeling of the goat population of Benin under climate change scenarios显示文摘Background:Insufficient knowledge of the genetic and phenotypic diversity in the local Beninese goat population combined with the lack of understanding of its adaptive capacity to ongoing environmental and societal changes hampers the development of strategies for better management and genetic improvement.The objective of this study was to establish the current geographical distribution of goats in Benin based on their morphology and model the potential habitat suitability of the three known main goat phenotypes(i.e.,Djallonkégoat or TypeⅠ,Sahelian goat or TypeⅡ,and their Crossbreeds or TypeⅢ)under climate change scenarios.Ten qualitative and 26 linear body measurements were taken on 2114 adult female goats sampled across the three vegetation zones of the country.Fifteen ratios were generated from the quantitative variables.The data were analyzed using generalized linear model procedures followed by multiple comparisons of least-squares means and multivariate analytical methods,including canonical discrimination analysis and hierarchical ascendant classification.Each goat was then assigned to one of the three aforementioned main goat phenotypes following its morphological characteristics and according to the a priori cluster membership defined in the previous step.The Maximum Entropy algorithm was used to model the current and future distribution of the three goat phenotypes under climate change scenario using the Representative Conservation Pathways 4.5 and 8.5.Results:All linear body measurements varied among vegetation zones.In the discriminant function analysis,71%of the measured individuals were correctly classified in their vegetation zone of origin by seven measured variables and three ratios.The cluster procedure analysis revealed two groups of goats subdivided into the three main phenotypes.The modeling results showed that the currently highly favorable habitats were distributed in the South for TypeⅠ,in the North for TypeⅡ,and both South and North for TypeⅢ.However,under climate change scenarios,the favorable habitats for TypeⅠdecreased while those of TypesⅡandⅢincreased.Conclusions:The results of this study confirm the spatial variation of the goat population in Benin.The habitat suitability model can be used to support decision-making toward better management of goat genetic diversity in Benin. | Habib Rainier Vihotogbe Whannou Cossi Ulriche Afatondji Côme Agossa Linsoussi Gnimansou Abraham Favi Thanh Thi Nguyen Marcel Romuald Benjamin Houinato Luc Hippolyte Dossa | 2022 | Ecological Processes2022，11，1： | 0 |
