Optimum Concentration of Glucose and Orange II for Growth and Decolorization of Orange II by Enterococcus faecalis ID6017 under Static Culture
(2008)Growth and decolorization performance of bacterial grown on azodyes-containing-medium is influenced by various concentrations of carbon sources and azodyes. The optimum level of glucose and Orange II concentration for ... -
Pembentukan Magnetosom pada Bakteri (Magnetosome Formation in Bacteria)
(2004)Magnetic bacteria orient and navigate along geomagnetic field lines and are widely distributed in freshwater and marine habitat. The ability of these bacteria to respond to magnetic fields is based on the presence of ... -
Perpustakaan Gen: Bagaimana Mengonstruksinya?
(2001)Many methods can be used to construct genomic DNA library in the cosmid vector. In this system, large fragments of genomic DNA generated by randomly digestion are ligated to the cosmid vector to form concatemers that can ... -
Phenotypic, Metabolic, and Genetic Diversity of the Indonesian Isolates of Rhizopus oligosporus
(2007)Fifteen Rhizopus oligosporus isolates were isolated from a number of tempeh samples obtained from Mataram, Jember, and Bogor, Indonesia; and subjected for characterization based on phenotypic, metabolic, and genetic ... -
Phylogenetic Evidence that Two Submerged-Habitat Fungal Species, Speiropsis pedatospora and Xylomyces chlamydosporus, Belong to the Order Jahnulales Insertae Sedis Dothideomycetes
(2008)The genera Speiropsis and Xylomyces are anomorph fungi. The taxonomic address for the fungi has been unclear. In this study, observation of morphological traits indicates that they have a unique pattern of mycelia with ... -
Physiological Characterization and Molecular Identification of Denitrifying Bacteria Prosessing Nitrous Oxide High Reduction Activity Isolated from Rice Soils
(2010)Rice fields are one of the main source of high nitrous oxide N2O emission. Soil denitrifiers processing high N2O reduction activity are important for controlling N2O emission. Nitrous oxide reduction is the last step of ... -
Population Density of Wolbachia Bacteria and the Induction of the Popcorn-Effect in Drosophila melanogaster
(2008)Drosophila melanogaster is known to harbour Wolbachia bacteria that cause the early death of its adult host. The death occurs early as a result of cell rupture caused by the proliferation of Wolbachia within it. However, ... -
The Process of Xylanase Production from Bacillus pumilus RXAIII-5
(2007)The optimum conditions for the growth of Bacillus pumilus RXAIII-5 (a potential xylanase producer) were sought, these included temperature, pH, aeration, and agitation of the culture batch. Afterwards a mathematical model ... -
Production and Purification of Xylanase From Indonesian Isolate Bacillus sp. AQ-1 Grown on Bunch Palm Oil
(2008)Xylanase (endoxylanase, EC 3.2.1.8) is a commercial enzyme that has been applied in the industrial production of fuel, food, textiles and paper. Xylanase was isolated from the culture supernatant of Bacillus sp. AQ-1 grown ... -
The production of Blue Cheese with the Addition of Nonpathogenic Strain of Klebsiella pneumoniae and Fortification of Folic Acid and Iron
(2010)Blue cheese is a semi-soft ripened chesee involves the growth of Penicillium roqueforti in the ripening process. Cheese has a longer ahelf life compared to raw milk and the production of cheese will give add value to the ... -
Production of Exopolysaccharides by Strains of Streptococcus thermophilus
(2010)Two strains of Streptococcus thermophilus producing capsular and capsular-ropy exopolysaccharides (EPS) were examined for their growth and EPS production in M17 medium supplemented with glucose, galactose or lactose and ... -
The Production of Nata Colored by Monascus Purpureus J1 Pigments as Functional Foods
(2010)Pigmen from Monascus sp. may color nata. The mold also produces monacolin K that inhibits HMG-CoA reductase affecting the reduction of blood cholesterol. The aim of this study was to produce the colored nata containing ... -
The Production of Tannin Acyl Hydrolase from Aspergillus niger
(2007)The aim of this research was to produce tannin acylhydrolase (tannase) from Aspergillus niger isolated from cacao pod. The first step of the study included determination of optimal pH, temperature, and incubation period ... -
Products of Orange II Biodegradation by Enterococcus faecalis ID6017 and Chryseobacterium indologenes ID6016
(2007)Chryseobacterium indologenes and Enterococcus faecalis were isolated from activated sludge of textile wastewater treatment plant. These bacteria had the ability to decolorize several azo-dyes. Degradation of azo dyes was ... -
Prospective Use of 1-Aminocyclopropane-1-Carboxylate Deaminase-Producing Bacteria for Plant Growth Promotion and Defense against Biotic and Abiotic Stresses in Peat-Soil-Agriculture
(2008)The 1-aminocyclopropane-1-carboxylate (ACC) deaminase (EC4.1.99.4) is an enzyme produced by some soil bacteria to degrade ACC (the immediate precursor of ethylene) to reduce ethylene biosynthesis in higher plants. Increased ... -
Protein Patterns in Arbuscular Mycorrhizal Roots and Non-Mycorrhizal Roots of Oil Palm Seedling
(2007)A comparison of the protein patterns in root extracts from none mycorrhizal and mycorrhizal oil palm roots has been made. The polypeptides were analyzed every three weeks up to 11 weeks. A factorial design of fungi species ... -
