Research ArticleOpen accessIn the abstractProduction of Bacillus Subtilis as Biological Fertilizer by Biotransformation of Corn Steep LiquorXiaojie Ren, Baoyue Liu et al.Corn steep liquor is a kind of intractable organic waste liquidproduced during the processing of corn starch. But it is rich in nutrients,soluble protein, and amino acids and it could be used as a nitrogen source inthe fermentation industry. Many starch processing enterprises cannot directlyutilize corn steep liquor and choose to discharge it directly, thus causingenvironmental pollution. Studies have shown … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 10 Nov 2022 · 7,382 accessesView PDFCite

The purposes of this study are to investigate concentration characteristics and sources analysis of heavy metals in Taoyuan coal mine of Suzhou City. 30 soil samples were collected and characterized for metal concentration (Cd, Cr, Cu, Pb, Zn and As), … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 29 Jan 2022 · 5,914 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Chlorophyll-an in a Small Reservoir by Landsat 7 ImageryMaryam Ghashghaie, Kaveh Ostad-Ali-Askari, Saeid EslamianChlorophyll-a (chla) is a source of water pollution. Monitoring the quality of water in reservoirs is necessary to take any action for protecting the water quality. Traditional methods of sampling are usually costly and time consuming. Also they need skillful labors and some areas are out of reach or sampling at those areas is dangerous. Remote sensing technology could solve … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 Apr 2018 · 8,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization, Characterization and Antioxidant Activities of Selenized Polysaccharides from Hypsizygus marmoreusTing Liu, Xue Jiang, Wei Wang, Bing XuIn this study, hypsizygus marmoreus was used as raw material to extract polysaccharides by hot water extraction method. Preparation technology of Selenized Polysaccharides from Hypsizygus marmoreus (SPHM) and its antioxidant activities were investigated. Chelation rate was selected as the index, effects of initial concentration of sodium selenite (mg/mL), the mass ratio of polysaccharide to sodium selenite, chelation time and pH … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 8 Aug 2019 · 7,774 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Hydrolysis Conditions for Obtaining Antithrombotic Peptides from Tenebrio Molitor LarvaeFangyuan Chen, Han Jiang, Yini Gan et al.Tenebrio molitor larvae was hydrolyzed by pepsin and trypsin for preparing high antithrombotic activity hydrolysate. The significant variables were selected according to the Plackett-Burman design and further optimized by the Response Surface Methodology (RSM). Four factors, including substrate concentration, pepsin digestion time, pepsin amount and trypsin amount, respectively, influenced significantly on the hydrolysis effectiveness. The best hydrolysis conditions obtained using … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 20 May 2019 · 8,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimized Biodiesel Production from jatropha curcas oilHaruna Musa, Daniel Eric, Alkhairu Hassan et al.In this study, a mathematical model for the trans-esterification reaction of jatropha curcas seed Oil (JCO) was developed using Response Surface Methodology(RSM) in terms of operational variables such as temperature (50 to 80°C), catalyst concentration (0.7 to 1% in relation to oil mass) and methanol/oil ratio (3:1-9:1), at fixed reaction time (90 min) and mixing intensity. Biodiesel was produced by … …Energy Research Journal, Vol. 12, Issue 1 · 12 Oct 2021 · 7,286 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlavonoids from the Zizania latifolia Bracts: Extraction Optimization, Antioxidant Activity and Exploration in Strawberry PreservationTong Wang, Yuzhu Zhang, Lijie Ben et al.Zizania latifolia bracts are Z. latifolia-based agricultural waste materials, distributed in various parts of the world. In the current study, the Response Surface Method (RSM) was used to optimize the cellulase-assisted extraction of Total Flavonoids from Z. latifolia bracts (TFZB). Then, the in vitro antioxidant capacity and the potential effect on strawberry preservation were assessed. The results showed that the … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 15 Mar 2021 · 6,363 accessesView PDFCite
Research ArticleOpen accessIn the abstractExogenous Progesterone for Offspring Sex Ratio Manipulation in Arabic Chickens (Gallus turcicus) Leading to Increasing Female Chicks ProportionIswati, Muhammad Halim Natsir, Gatot Ciptadi, Trinil SusilawatiFemale birds of egg-laying hens are more valuable than males, because males bird have no commercial value. The opportunity to manipulate offspring sex ratio in poultry has been observed in female birds; hence, female birds have heterogametic ZW chromosomes. High progesterone concentration 2-5 h before ovulation is thought to affect the segregation of female sex chromosomes as the basis for … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 17 Feb 2021 · 7,500 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimisation of Plant Mineral Nutrition, Growth Stimulation and Yield Enhancement Through the Use of a Bio Formulation Based on Phosphate Solubilising BacteriaZhanar Zhumadilova, Laura Tokhetova, Gulsim Baimbetova et al.The aim of this study was to evaluate the agronomic and fodder efficiency of various fertilisation treatments in relation to their effects on plant growth, chemical composition, and soil properties. The study evaluated the effectiveness of a bio-formulation based on Phosphate-Solubilising Bacteria (PSB) in combination with mineral fertiliser (N60P90 + N30) in enhancing the productivity of forage crops and improving … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 23 Sep 2026 · 385 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn vitro Polyploid Induction in Phalaenopsis Aphrodite by PendimethalinPrasetyorini Djarot, Deden Sukmadjaja, Fadya Annisa Chaesarani, SukonoPhalaenopsis aphrodite is a type of orchid with high ornamental and economic value. However, its development for commercial needs in Indonesia is still hindered by the limited availability of varieties. Therefore, enhancing genetic diversity is necessary, one of which is through polyploid induction. Several previous studies reported that pendimethalin effectively duplicates the chromosome numbers of various plant species.
