(1999)Genes for J3 and cc polypeptides of the lightharvesting I I complexes in Rhodobacter sphaeroides 2.4.1 are encodcd by the pucBA operon, and their expression is highly rcgulated by oxygen level and light intensity. ... -
The Activity of Antibacterial Substance Isolated from Kaliandra's Honey
(1999)Experiments were conducted to determine the activity of antibacterial substance isolated from Kaliandra's honey. The honey could inhibit some bacteria, such as Enterobacter cloacae, Salmonella typhimurium, and Escherichia ... -
Isolation and characterization of a thermophilic lipase from Bacillus thermoleovorans ID-1
(1999)thermophilic microorganism, Bacillus thermoleovorans ID-1, isolated from hot springs in Indonesia, showed extracellular lipase activity and high growth rates on lipid substrates at elevated temperatures. On olive oil (1.5%, ... -
Transfer Gen inaZ pada Beberapa Galur Bradyrhizobium japonicum Toleran Asam-Al
(1999)The objective of this research was to study the expression of ice maclearion gene (inaZ) in several Bradyrlxizobizmx japonicum acid-Al tolerant strains in free living and bacteroid stage. The test strains, i.e. 05, 09,15, ... -

Pemanfaatan Limbah Industri Tapioka Sebagai Pupuk Cair Pada Tanaman Sayuran Vol VII, No 2, 2001
(2001)The objectives of this experiment were to study vegetable crops which have good response and to find the optimal interval time of liquid fertilizer application from tapioca wastewater to increase vegetable crops yield. The ... -
Electroretinogram analysis of relative spectral sensitivity in genetically identified dichromatic macaques
(2001)The retinas of macaque monkeys usually contain three types of photopigment, providing them with trichromatic color vision homologous to that of humans. However, we recently used molecular genetic analysis to identify several ... -
Microorganisms with a Taste for Vanilla: Microbial Ecology of Traditional Indonesian Vanilla Curing
(2001)The microbial ecology of traditional postharvesting processing of vanilla beans (curing) was examined using a polyphasic approach consisting of conventional cultivation, substrate utilization-based and molecular identification ... -
