Activity of proteolytic and Amylolytic enzymes from Bacillus spp. Isolated from shrimp ponds
IT Jamilah | Meryandini, Anja | Rusmana, Iman | Suwanto, Antonius | Mubarik, Nisa Rachmania (2009)Accumulation of feed excess in commercial shrimp ponds due to overfeeding could decrease water quality. Protein and starch are the primary components of shrimp feed. This study was conducted to characterize extracellular ... -
Defense against Biotic and Abiotic Stresses in Peat-Soil-Agriculture
Husein, Edi | Triwahyudi, Aris | Suwanto, Antonius | Saraswati, Rasti (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 ... -
The Dynamics of Bacterial Communities During Traditional Nata de Coco Fermentation
Seumahu, Cecilia Anna | Suwanto, Antonius | Hadisusanto, Debora | Suhartono, Maggy Thenawidjaja (2007)One of the important problems in traditional Nata de Coco (Nata) fermentation is production inconsistency due to strain or genetic variability reflecting mixed microbial communities involved in this process. This research ... -

Suryanto, Dwi | Suwanto, Antonius (2002)l'otal geno~nic analysis of three anorygenic photosynthetic bacteria. 1)s-I, 1)s-4 and Cas-13, was done using hlaero-l~estrictiao Fragment 1,ength Polymorphism technique employing pulsecl-field gel electrophoresis. 'L'lie ... -
Evidence for a Link Between Pathogenicity and the Role of Imp Bacterial Transport Effector Proteins in Soybean Infection by Xanthomonas axonopodis pv. glycines
Fitriani, Any | Suwanto, Antonius | Wahyudi, Aris Tri | Tjahjono, Budi (2007)Xanthomonas axonopodis pv. glycines (Xag) is the causal agent of bacterial pustule disease of soybeans. A nonpathogenic mutant of Xag (M715) was constructed employing transposon mutagenesis which showed similar epiphytic ... -
Evidence for a Link Between Pathogenicity and the Role of Imp Bacterial Transport Effector Proteins in Soybean Infection by Xanthomonas axonopodis pv. glycines Vol 1, No 2, 2007
Fitriani, Any | Suwanto, Antonius | Wahyudi, Aris Tri | Tjahjono, Budi (2007)Xanthomonas axonopodis pv. glycines (Xag) is the causal agent at bacterial pustule disease of soybeans. A non-¬pathogenic mutant of Xag (M715) was constructed employing transposon mutagenesis which showed similar epiphytic ... -
Genetic Diversity of Antifungi-Producing Rhizobacteria of Pseudomonas sp. Isolated from Rhizosphere of Soybean Plant
Susilowati, Ari | Wahyudi, Aris Tri | Lestari, Yulin | Wiyono, Suryo | Suwanto, Antonius (2010)Antifungi-producing rhizobacteria have been regognize playing an important role in plant desease supression. In our laboratory, 13 indigenous soybean rhizobacteria Pseudomonas sp. that showed strong growth inhibition of ... -
Isolation and Identification of Ice-Nucleating-Active Bacteria from Indonesian Edible Leafy Plant Poh-Pohan (Pilea glaberina)
Waturangi, Diana Elizabeth | Meicy, Vicky | Suwanto, Antonius (2008)Two ice-nucleating-active (INA) bacteria (isolates C and 6) were isolated from poh-pohan (Pilea glaberina), an Indonesian edible leafy plant (lalaban). The maximum nucleation temperature of aqueous suspensions of the two ... -
Keragaman Genetika Bakteri Tanah dari Rizosfer Kapas Transgenik dan Nontransgenik di Soppeng, Sulawesi Selatan
Yusuf, Muhammad | Hala, Yusminah | Suwanto, Antonius (2002)Techniques based on amplification of 16s-rRNA genes for comparing bacterial communities are now widely used in microbial ecology. In this study, we compared bacterial genetic diversity of transgenic and nontransgenic cotton ... -

Prihatna, Cahya | Suwanto, Antonius (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 ... -
Physiological Characterization and Molecular Identification of Denitrifying Bacteria Prosessing Nitrous Oxide High Reduction Activity Isolated from Rice Soils
Setyaningsih, Ratna | Rusmana, Iman | Setyanto, Prihasto | Suwanto, Antonius (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 ... -
