Agricultural activities contribute to the global warming as sources of CH4 and N2O emissions. Application of methanotrophic bacteria, Ochrobactrum anthropi, Azotobacter and Azospirillum combination could reduce the emission of CH4 and N2O. In addition, these bacteria can fix nitrogen (N2) to enhance the plant growth. The aim of this study was to determine the effectivity of methanotrophic bacteria, Ochrobactrum anthropi, Azotobacter and Azospirillum combination as biofertilizer and emission reducer of CH4 and N2O in the inorganic paddy fields. This experiment was arranged by treating 100% dosage of inorganic fertilizer as positive control, 25% dosage of inorganic fertilizer and 25% dosage of inorganic fertilizer mixed by biofertilizer. The observations were made on the growth parameters and the rate of gas fluxes. The combination of bacterial isolates could increase rice growth, grain yield productivity by 67.53% and they also could reduce CH4 and N2O emission. ","PeriodicalId":437476,"journal":{"name":"Journal of medical and bioengineering","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128421196","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}

This complex mix culture fermentation produces metabolic products that serve as the precursors for the flavor development process. Modification in the dynamics of microbial population during the fermentation may alter the overall microbial activity and thus may impact the fermentation process. Addition of microbial starter was thus suggested to improve the cocoa bean fermentation process. This paper discusses the effects of Lactic Acid Bacteria (LAB) starter addition to the cocoa bean fermentation. Dynamics in microbial population, i.e. yeast, lactic acid bacteria, and acetic acid bacteria were analyzed as well as the sugar components, metabolic products, and the fermentation index during the fermentation. The addition of LAB starter was observed to accelerate the growth of both lactic acid bacteria and acetic acid bacteria, leading to the increase in the ethanol, lactic acid, and acetic acid concentration. Overall it increases the fermentation index and potentially shorter the fermentation time. ","PeriodicalId":437476,"journal":{"name":"Journal of medical and bioengineering","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116837569","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}

Nevertheless, there is still lack of reliable data and theory that could best define skin deformation behaviour. Therefore, this paper aims to quantify the biomechanical properties of bovine under uniaxial tension skin utilising experiment-numerical approach. Bovine skin samples were tested according to ASTM D2209-00 standard to obtain stress-stretch data. Based on the experiment data, a programme is written using Matlab to quantify and determine the bovine skin biomechanical properties. The Ogden parameters are found to be μ = 0.4 and α = 4.6.

Although several substrates for the production of tannase have been reported as being economically effective such as utilization of tanninrich substrate rather than pure tannic acid, however, there is still need to develop the substrate to make the entire process much cheaper and more effective. Here we reported tannase production from Erwinia as there is not found any report on tannase production from Erwinia. The present work deals with physiological studies on bacterial tannase. Out of 50 spoilt cucumber and tomato samples from local markets in Baghdad city. Eleven isolates from Erwiniacarotovora were obtained (22%). Tannase activity was found in 7 isolates in primary and secondary screening and the isolate ErwiniacarotovoraEt3yielded the highest tannase production. The enzyme activity was increased to 62.6 U/ml when this isolate was cultivated under the optimal conditions which consisted of using basal medium containing(5% w/v) pomegranate peels extract and (2% w/v)ammonium nitrate with pH 5.0 at 30°C for 24 hour. The metal ions K, Ca, Na, Mg and Mn did not affect enzyme production. However, metal ions like Zn, Cu, Co, Fe and detergents inhibited the production of tannase. The enzyme revealed maximum activity (79.50U/ml) with pomegranate peels powder(1% w/v), followed by eucalyptus and pine barks powders with relative activities of 127,112 and 103%, respectively, as substrates. Consequently, pomegranate peel has a potential as an effective and much cheaper (economical) substrate for tannase production and tannase activity in comparison with traditionally used substrates like tannic acid and other saccharides.","PeriodicalId":437476,"journal":{"name":"Journal of medical and bioengineering","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125461996","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}
