Research ArticleOpen accessEvery word in the titlePolygalacturonase and Pectin Methylesterase Activities of CaCl2 Treated Red-Fleshed Dragon Fruit (Hylocereus polyrhizus) Harvested at Different MaturityY. B. Awang, S. H. Chuni, M. T.M. Mohamed et al.Fruits harvested at different maturity possess different biochemical constituents and physiological properties that make the fruits may react somewhat differently to the postharvest treatment. A study to examine the activity of Polygalacturonase (PG) and Pectin Methylesterase (PME) enzymes during storage in dragon fruit (Hylocereus polyrhizus) harvested at 28 days (Index 3) and 34 days (Index 5) after anthesis and postharvest … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 23 Jul 2013 · 8,433 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Mother Plant and Somatic Embryo Registry for the Propagation and Conservation of Artificial Seeds of the Orchid Phragmipedium kovachiiOsber Cunia, Manuel Oliva, Segundo G. Chavez et al.Phragmipedium kovachii, is an endemic orchid that naturally inhabits the humid zones of the Amazonas region in Peru. Currently, it has been extracted from its natural habitat, listed as critically endangered by CITES, suggesting searching for conservation strategies in vitro and in situ. Therefore, this research established an in vitro protocol to obtain and conserve artificial seed, through four events: … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 8 Jul 2024 · 5,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Identification of a Bioflocculant-Producing Strain and Application in Rice Vinegar ClarificationWeilian Hu, Dehui DaiA bioflocculant-producing bacterium S-3# was isolated from fresh sand bones 40-50 cm underground in the desert region of China’s Ningxia Province. It was identified as Paenibacillus sp. based on 16S rDNA sequence along with its biochemical and morphological characteristics. Chemical analysis found that the bioflocculant from S-3# is mainly composed of extracellular polysaccharide. Researchers observed no noticeable change (above 91%) … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 30 Dec 2020 · 5,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Effects of Different Calcium-Magnesium Conditioners on LatosolJin Li, Yingbin Xue, Minzhong Chen et al.At present, soil acidification seriously restricts the sustainable development of agricultural production. A common method that can be used to improve acidified soils is to apply calcareous materials (conditioners), but there is difference in the improvement effect of the conditioners on the same soil because of the conditioners containing different calcium-magnesium compounds. In order to find suitable conditioners for latosol … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 13 Oct 2020 · 6,626 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Organic Carbon Pool and its Storage in Arial Beel Wetland Soils of BangladeshMd. Faruque Hossain, ASM Maksud Kamal, Monera Akhter Eva et al.The actual quantity of Soil Organic Carbon (SOC) stored in wetlands can only be estimated within a broad range of uncertainty. An accurate assessment of the size and distribution of the SOC storages in wetland resources is very difficult to obtain, therefore, the proposed research objective is to measure SOC storage and its pool on wetland soils of Arial beel … …American Journal of Environmental Sciences, Vol. 16, Issue 3 · 17 Aug 2020 · 7,382 accessesView PDFCite
Research ArticleOpen accessIn the abstractFractionation of Organic Carbon in Arial Beel Wetland Soils of BangladeshMonera Akter Eva, Mahmudul Islam Piash, Md. Faruque Hossain, Zakia ParveenA study was conducted to determine the organic carbon fractions in the vertical sections of a benchmark wetland soil of Bangladesh (Arial Beel) and their dynamics that directly affect the biogeochemistry of soil, water and plant biomass ecosystem. Two distinctive soil series viz. Sara and Arial are characterized such as pH, moisture content, textural class, CEC, organic carbon (SOC), bulk … …American Journal of Environmental Sciences, Vol. 14, Issue 2 · 4 May 2018 · 9,134 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatistical Improvement of Batch Culture with Immobilized Pichia pastoris Cells for rPOXA 1B Laccase ProductionMichelle Gouzy-Olmos, Luis M. Cháves-Tequia, María F. Rojas-Fajardo et al.Immobilized Pichia pastoris X33/pGAPZαA-LaccPost-Stop in Ca2+ alginate beads was employed for Pleurotus ostreatus rPOXA 1B laccase batch production. Sequential statistical improvement was achieved through Plackett-Burman (PBED), (PBED-T11, 29.5±0.8 UL-1), which allowed to increase activity by 2.36-fold (12.5±2.6 UL-1) obtained in a preliminary study. Following, Box-Behnken Experimental Design (BBED) was implemented and obtained enzymatic activity in PBED-T11 was further increased by … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 26 Apr 2018 · 11,776 accessesView PDFCite
Research ArticleOpen accessIn the abstractPOST-HARVEST CONTROL OF APPLE BLUE MOLD UNDER COLD STORAGE CONDITIONSZiad B. Al-Rawashdeh, Muwaffaq R. KarajehTo control blue mold of apples caused by Penicillium expansum after harvest and during commercial cold storage, microwave exposure was investigated as a physical measure and compared with the use of calcium chloride and the systemic fungicide, carbendazime. Microwave exposure of Golden Delicious and Royal Gala apples at 2450 Mhz for 10, 30 and 45s was effective as 4% CaCl2 … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 23 Jan 2014 · 7,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Bet and Water Adsorption TechniquesB. H. Diya’uddeen, I. A. Mohammed, B. Y. Jibril, I. M. BugajeThe effect of activated carbon surface area on the amount of fluid adsorbed is significant. Thus, the surface area of an adsorbent is an important factor. The use of the costly BET measurement method is the standard. However, water adsorption method was proposed as an alternate method. Nevertheless, results presented were for activated carbon prepared and surface areas reported were … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 7,246 accessesView PDFCite
