Research ArticleOpen accessIn the abstractChemical Compositions and Resistant Starch Content in Starchy FoodsAnuchita MoongngarmResistant Starch (RS) is one of nature’s most interesting bioactive compounds. There is a wide variety of starchy food plants in Thailand that are good sources of RS, but they have not been well studied. As such, this study was carried out to investigate the potential food source of RS. Twenty-two promising food plants were selected. The samples included (1) … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 28 Mar 2013 · 15,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Anaerobic Fermentation of Simple Sugars by Yeast Fuels Resistance Candida spp. Infections to Eradication by DrugsNedosa Ikenna Valentine, Utoh-Nedosa Uchechukwu Anastasia, Dan Danjuma et al.Problem statement: Human systemic Candida infections had proved difficult to eradicate by the medical health care system. Some practitioners and scholars see the problem as being due to drug resistance. For example an author wrote that ‘secondary drug resistance is clearly being encountered in one setting, oropharyngeal candidiasis in patients with advanced Human Immunodeficiency Virus type 1 (HIV-1) infection usually … …American Journal of Infectious Diseases, Vol. 7, Issue 4 · 10 Dec 2011 · 7,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractSlow Fungal Hydrolysis of Complex Sugar is Responsible for the Use of Sugar as Vehicle for Antifungal DrugsNedosa Ikenna Valentine, Utoh-Nedosa Uchechukwu Anastasia, Dan Danjuma et al.Problem statement: Aspergillus niger strain (UUF 9202) significantly reduced the dormancy period and boosted aggregate germination time in seeds of Tetrapleura tetraptera by 42% in 32 days and produced a net reduction in mean germination time of the seeds to 12 days. A structure-fungitoxicity relationship study of a series of isoflavonoids against Aspergillus niger and Cladosporium cucumerinum showed that a … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 3 · 2 Nov 2011 · 7,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification a Novel Raw-Starch-Degrading-α-Amylase from a Tropical Marine BacteriumZeily Nurachman, Alfredo Kono, Ocky Karna Radjasa, Dessy NataliaProblem statement: Bacteria from the surface of the tropical marine hard coral Acropora sp. were screened for producing raw-starch-degrading-α-amylase. Approach: Based on its 16s rDNA sequence, a bacterium that produced the highest amylolitic activity was identified as Bacillus amyloliquifaciens ABBD. The bacterial isolate secreted a α-amylase extracellularly and then the enzyme was partially purified by ammonium sulfate precipitation followed by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractAmphoteric Starch in Simultaneous Process Preparation with Box-Behnken Design for Optimal ConditionsSopa Cansee, Juntanee Uriyapongson, Commueng Watyotha et al.Cassava starch was chemically modified to produce an amphoteric starch. The amphoteric starch was prepared in a simultaneous process which was evaluated in relation to four factors: temperature (45-55 °C), 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC, 4-12%) and sodium tripolyphosphate (STP, 2-8%) concentrations, and reaction time (2-6 h). The extent of amphoteric starch produced was determined by the degree of substitution (DS) of … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,523 accessesView PDFCite
