Effects of hemB Antisense RNA on δ-Aminolevulinic Acid Production in Rhodobacter sphaeroides
(IPB (Bogor Agricultural University), 2002)
Genes for β and α polypeptides of the light harvesting II complexes in Rhodobacter sphaeroides 2.4.1 are encoded by the pucBA operon. Their expression is highly regulated by oxygen level and light intensity. δ-Aminolevulinic ...

Isolasi dan Karakterisasi Bakteri Asal Laut Sulawesi untuk Biokontrol Penyakit Vibriosis pada Larva Udang Windu (Penaeus monodon Fab.)
(IPB (Bogor Agricultural University), 2003)
Six-hundred and three isolates of marine bacteria have been isolated from Sulawesi Sea and analysed for their inhibitory effects toward Vibrio harveyi both in vitro and in vivo experiments. Fifteen isolates demonstrated ...
Survival and Epiphytic Fitness of a Nonpathogenic Mutant of Xanthomonas campestris pv. Glycines
(IPB (Bogor Agricultural University), 2000)
Xantliomonas campestris pv. glycines is the causal agent of bacterial pustule disease of soybeans. The objective of this work was to construct a nonpathogenic mutant derived from the pathogenic wild-type strain YR32 and ...
Plsed-Field Gel Electrophoresis A Revolutional in Microbial Genetics
(IPB (Bogor Agricultural University), 1994)
Gel electrophoresis is a relatively simple but reliable technique for the analysis of DNA and RNA molecules. However, this method, in practical terms, cannot resolve the separatioo of DNA fragments more than 50 kilo base ...
Presence of hemALike and hemT-Like Genes in a Number of Anoxygenic Photosyn
(IPB (Bogor Agricultural University), 2000)
l'lle l~lrodohuc~seprl ~ueroidesh errrA and hemT are known to erlcodc a distinct 5-:~r~~inolevdlinic acid (ALA)-synthase isozynle. This enzyme catalyzes the first and rate limiting step in ALA biosyn(blcsis through tllc ...
Novel beta-Lactamase Genes from Two Enironmental Isolates of Vibrio Harveyi
(IPB (Bogor Agricultural University), 2000)
Two ampicllin-resistant (Amp) isolates of Vibrio harveyi, W3B and HB3, were obtained from the coastal waters of the Indonesian island of Java. Strain W3B was isolated from marine water near a shrimp farm in Nort Java while ...
