The andosols in Indonesia
(1965)In the last few years three have been several studies of the andosols. Since this group of balck-colored soils is widely distributed inthe volcanic areas around the gradually receiving more attention. The unusual behavior ... -
Nitrogen, energy and vitamin nutrition of Rhizobium japonicum
(1968)The energy, nitrogen and vitamin nutrition of 36 strains of Rhizobium japonicum were investigated. Most of the strains utilized gluconate, glycerol, arabinose, glucose, mannose, mannitol, sorbitol, galactose and maltose. ... -
Fatty Acid Composition of Monkey Milk Lipids
(1974)Milk from 6 species of monkeys contained 2.2–8.5% total lipids, and 11.5–16.5% total solids. The fatty acid composition of the milks, as determined by an improved gas liquid chromatographic techniques, was generally similar ... -
Intramolecular Fatty Acid Distribution in Milk Fat Triglycerides of Monkeys
(1974)Pancreatic lipase hydrolysis was used to determine the distribution of fatty acids in the milk triglycerides of four species of monkeys and of human milk. The patterns of the major fatty acids were generally similar in all ... -
Mycoflora of "Ragi" and Some Other Traditional Fermented Foods of Indonesia
(1974)Studies had been conducted on the mycoflora of samples of "ragi", "tape ketela" or "peuyeum", "tape ketan hitam", "oncom hitam", and "oncom merah" or "oncom beureum" from various places in WE'~'lt Java. The organisms that ... -
Vitamin B12 content of fermented foods in the tropics
(1983)The vitamins B12 (V. B12) content of fermented foods transforted from tropical countries was analysed. Of tjose, Tempeh was an interesting example, because it is made of soybeans and contained a comparatively large amount ... -
Genetic variability of foxtail millet (Setaria ita!ica P. Beauv.)
(1985)The ge netic d ivu$ity of a world eollection of fO~18il millet ~trains (Setaria italiea) and somt samples of wild populations (Selaria viridis) was studied by meln5 of electrophoresis on live en~ymt5 ( 10 loci) Est. Acph. ... -
The Relative Abundance of Benthic Macroinvertebrates in Relation to Eutrophication Processes in Lake Rawa Pening, Central Java, Indonesia
(1987)Physico-chemical conditions (as supporting data) and benthic macroinvertebrates were studied in Lake Rawa Pening from May 1980 to April 1981. Samples of benthic animals and of physicochemical conditions were collected at ... -
Palmar and plantar dermatoglyphics in macaques: A revised method for their description
(1989)A revised method for the description of the palmar and plantar dermatoglyphics in macaques, genusMacaca, is proposed. The method was deduced from the authors' recent observations of numerous dermatoglyphic prints from ... -
A Packed Bed Solid-State Cultivation System for The Production of Animal Feed: Cultivation, Drying and Product Quality
(1992)A Standing column packed bed bioreactor was constructed to enable packed bed opertaion during solid-state cultivation (SSC) of sago strach by R. oligosporus UQM 145F, to be followed by in situ drying of the microbial product. -
Identification and characterization of genes induced during sexual differentiation in schizosaccharomyces pombe
(1993)Five cDNA clones, harboring genetic messages preferentially expressed during the sexual differentiation process, were isolated from a cDNA library of Schizosaccharomyces pombe by subtractive screening. Transcription of the ... -
Tkansgenic Burley and Flue-Cured Tobacco with Resistance to Four Necrotic Isolates of Potato Virus Y
(1995)Transgenic burley (cultivars KY 14, NC3433-33, and TN90) and fluecured (cultivar K326) tobacco with resistance to four necrotic isolates of potato virus Y {WY) were constructed. These tobacco cultivars were transformed ... -
Screening of acid aluminium tolerant Bradyrhizobium japonicum strains: analysis of marker genes and competition in planta
(1997)The genes, inaZ from Pseudomonas syringae, xylE from P. putida and the kanamycin resistance gene (KmR) of mini-Tn5Km1, were studied for their capabilities and reliabilities as molecular markers in three acid tolerant ... -
The Effects of Milling Degree and Type of Bag on Fungal Infection and Some Chemical Contents of Stored Milled Rice
(1997)The effects of milling degree and type of bag on fungal infection of stored milled rice were investigated together with some chemical contents (glucose, amylose, protein and total lipid contents), and changes in moisture ... -
Discrimination of Macaques by Macaques: The Case of Sulawesi Species
(1997)A series of work by the first author have demonstrated that many macaque species show a visual preference for the pictures of their own species when the monkeys actively press a lever to see the pictures. We expanded this ... -
Novel Bacillus thuringiensis serovar aizawai strains from nulberry leaves in Indonesia
(1998)Bacillus thuringiensis isolates have been recovered from numerous sources, including soil, grain dust, plant leaves, diseased insect larvae from insectaries, and sericulture environments. During a study of B. thuringiensis ... -
Screening of acid aluminium tolerant Bradyrhizobium japonicum strains: analysis of marker genes and competition in planta
(1998)The genes, inaZ from Pseudomonas syringae, xylE from P. putida and the kanamycin resistance gene (KmlR) of mini-Tn5Km1, were studied for their capabilities and reliabilities as molecular markers in three acid tolerant ... -
Metabolism and excretion of oestradiol-17β and progesterone in the Sumatran rhinoceros (Dicerorhinus sumatrensis)
(1998)-labelled oestradiol-17β and -progesterone were injected i.v. into an adult female Sumatran rhinoceros (Dicerorhinus sumatrensis) and all urine and faeces collected over 4 days. Of the injected steroid, 68% of -oestradiol ...
