Biosurfactants are amphiphilic compounds cause surface tension reduction both aqueous solutions and hydrocarbon mixtures. The main purpose of this work was to characterize biosurfactant produced by Lactobacillus strains. Identification using 16s rDNA identified the isolates as L. acidophilus for Fm1 and L. pentosus for Y1. Effect different parameters (temperature, PH and Salinity) were studied to evaluate the stability of biosurfactant after treatment. In addition, critical micelle concentration of biosurfactant, emulsification index and viscosity reduction of palm and engine oils have been studied. The results revealed that, the biosurfactant from L. acidophilus and L. pentosus maintains its emulsifications activities unaffected in the wide range of parameter's study except slightly decreasing in emulsification index values at salinity 15%. The maximum reduction in surface tension was 18.05 mN/m with minimum concentration of critical micelle concentration of 7.5 mg/ml and high decrease of palm and engine oil viscosity of 110.1 and 165.3% respectively. This study concluded that, the emulsification activity, the surface activity and the stability to heat treatment, different PH and salinity of biosurfactant of Lactobacillus strains revealed the application of the biosurfactant in food, pharmaceutical, cosmetics industries and oil recovery.

The objectives of this study were to investigate nickel forms in tested soils and to determine the effect of industrial wastewater effluent irrigation on the metal fractions in soil. Data showed a remarkable increase in all tested Ni-forms in polluted soil. It could be concluded that soil composition has been changed with depth. Especially under such condition whereas, metal soluble organic compounds found in wastewater may precipitate and percolates through soil and may transport soluble Ni with the soil solution.","PeriodicalId":354866,"journal":{"name":"EPH - International Journal of Science And Engineering","volume":"189 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133813063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A resource allocation strategy based on evolutionary game is proposed to investigate the evolutionary process of user colony from the dynamic viewpoint. Using the method of replicated dynamics, an evolutionary stable strategy is produced to allocate resource. In particular, the evolutionary stable point, evaluation function characteristics, and replicated dynamic diagrams are discussed under different conditions. The results show that using evolutionary game approach, users could study and adjust strategy constantly through repeated games to achieve evolutionary stable equilibrium, which leads to an optimal allocation of resource.

The environmental catastrophe, which is now the most urgent issue on the planet, is also a threat to human life. There is currently scientific agreement that if greenhouse gas emissions are not reduced, humanity will suffer serious effects. Millions of people in underdeveloped countries are expected to experience water shortages, food grain shortages, and increased health and life hazards. Most of the world's cities may flood because of climate change. This could force hundreds of millions of people to leave their homes. They have already started to suffer; there will be deaths, and the environment will collapse. The environmental catastrophe of today is more artificial than natural.
