Sahariah Open Journal Systems <p>The International journal of Biotechnology, Bioinformatics and Biomedical encompasses multidisciplinary fields of Biotechnology, Bioinformatics and Biomedical. It endeavours pure and applied knowledges through advanced methodologies, technologies and or any new area which has potential in these areas and application of scientific inventions for benefit of the society. We invite scholars, academicians and all scientists’ society to share their valuable research in the form of review, research article, short communications through this platform for the better development and betterment of one and only earth. The aim of <strong>International Journal of Biotechnology, Bioinformatics, and Biomedical (IJBBB)</strong> is to propagate the knowledge and establish the communication amongst the researchers, academicians, industry personnel and policy makers.&nbsp;</p> External Nutrient Load and Determination of the Trophic Status of Lake Ziway 2018-09-17T10:54:26+0530 Dessie Tibebe Feleke Zewge Beshah Brook Lemma Yezbie Kassa Ashok N. Bhaskarwar <p>Lake Ziway is shallow freshwater located in Northern part of Ethiopian Rift Valley. Expansions of the flower industry, fisheries, intensive agricultural activities, fast population growth lead to deterioration of water quality and depletion of aquatic biota. The objectives of the present study are to evaluate the spatial and temporal variations in the external nutrient load and determine the trophic status of Lake Ziway in 2014 and 2015. The nutrients and Chlorophyll-<em>a </em>were measured according to the standard procedures outlined in APHA, 1999. From the result Ketar and Meki Rivers catchment showed the major sources of external nutrient loads to the lake ecosystem. The mean external soluble reactive phosphorus (SRP), total phosphorus (TP), total inorganic nitrogen (TIN) and total nitrogen (TN) loads to Lake Ziway were 230, 2772, 4925 and 24016 kg day<sup>-1</sup>, respectively. A general trend which was expected that the nutrient loads would be much higher in rainy season than in dry season. The mean concentrations of trophic state variables for TN, TP and Chl<em>a</em> were 6700, 212 and 42 mg L<sup>-1</sup>, respectively. The mean values of TSI-TP, TSI-Chl-<em>a</em>, TSI-TN and TSI-SD were 79, 66, 81 and 83, respectively and the overall evaluation of Carlson Trophic State Index (CTSI) of Lake Ziway was 77. Therefore, the lake is under eutrophic condition. The mean values of TN: TP ratio was 48 which were very high. The trophic state index determined with chlorophyll-<em>a</em> showed lower value than those determined with all trophic state indices values of TN, TP, and SD which indicated that non-algal turbidity affected light attenuation for algal growth. This suggested that phosphorus was the limiting nutrient in Lake Ziway. Due to its importance as being the lake is an intensive agricultural site, management solutions must be urgently developed in order to avoid the destruction of the lake.</p> 2018-09-01T14:50:12+0530 ##submission.copyrightStatement## Protein Separation Using Fly-ash Microfiltration Ceramic Membrane 2018-09-17T10:55:50+0530 Vandana Gupta Anandkumar J <p>In this study, separation of protein (bovine serum albumin (BSA)) was carried out by ceramic microfiltration membranes. Ceramic membranes were fabricated by using fly-ash with different proportion (2-8 wt%) of fuller clay and fraction (20 wt%) of inorganic additives. Synthesized ceramic membranes were characterized using scanning electron microscope, X-ray diffraction analysis, mechanical-chemical stability, porosity and pure water flux. It was observed that the mechanical and chemical stability of ceramic membrane increases with increase in fuller clay’s content. Ceramic membrane with 8% fuller clay (C<sub>4</sub>) exhibited maximum flexural strength of 20 MPa. C<sub>4</sub> membrane also shows least porosity of 29.9%, permeability of 0.397 L m<sup>-2</sup>h<sup>-1</sup>kPa<sup>-1</sup>, 20.15% water uptake capacity and 0.428 μm average pore radius. The BSA rejection efficiency of C<sub>4 </sub>membrane was studied for different operating parameter such as feed concentration (200-1000 mg/L), feed pH (2-10) and applied pressure (68-482 kPa). Maximum BSA rejection (82%) and flux (81 L m<sup>-2 </sup>h<sup>-1</sup>) has been observed at optimized condition (208 kPa, natural pH and 200 mg/L concentration). The results obtained in this work indicate that synthesized membrane could be used as proficient microfiltration membrane for protein rejection applications.</p> 2018-09-01T14:49:00+0530 ##submission.copyrightStatement## Landfill gases: Characteristics and treatment 2018-09-17T10:56:34+0530 Ashfaque Ahmad Piyush Sahu Biju Prava Sahariah <p>With the increase of population and change in lifestyle, the quantity and quality of solid waste has drastically changed in Indian society. Aspects involved in solid waste management are mostly, collection, transportation, disposal and processing. The disposal of solid waste is concerned with disposal process followed and availability of disposal land. Proper care should be taken in choosing the disposal area and disposal mechanism. Monitoring of the sites is priority criteria for successful management of solid waste as leachate generation occurs which is associated with ground water as well as surface water contamination near dumping sites. Surface water system situated near the disposal or landfill sites shows more toxicity as the dose of toxicants passage from the nearby landfill [1]. This note is simplified on the basis of guidelines on landfill gas management by SEPA, 2004 [2]. Through this short note, authors make a glimpse of landfill gas characteristics and management practices.</p> 2018-09-01T14:51:53+0530 ##submission.copyrightStatement##
