"The book begins from the essentials of singular systems theory and bifurcations before tackling the use of various forms of control in singular biological systems using examples including predator-prey relationships and viral vaccination and quarantine control. Researchers and graduate students studying the control of complex biological systems are shown how a variety of methods can be brought to bear and practitioners working with the economics of biological systems and their control will also find the monograph illuminating."

"Systems metabolic engineering is changing the way microbial cell factories are designed and optimized for industrial production. Christoph Wittmann and Sang-Yup Lee have assembled the world leaders on systems metabolic engineering and cover the full story, from genomes and networks via discovery and design to industrial implementation practises.

"Bawang merah (Allium ascalonicum L.) adalah komoditas sayuran dengan ancaman penyakit hawar daun bakteri yang disebabkan oleh Pantoea sp. dalam produksinya. Pemanfaatan agen biokontrol dari bakteri yang berasosiasi dengan akar tanaman berpotensi tinggi menghasilkan mekanisme penghambatan patogen pada tanaman. Penelitian ini bertujuan untuk memperoleh isolat bakteri agen biokontrol yang mampu menghambat pertumbuhan patogen Pantoea sp., mempelajari karakterisasi dan mekanisme aktivitas agen biokontrol dalam penghambatan patogen Pantoea sp., serta mengidentifikasi isolat bakteri agen biokontrol. Kultur bakteri kandidat agen biokontrol diisolasi dari tanah perakaran tanaman bawang merah di lahan pertanian bawang merah di Cirebon dan Majalengka, Jawa Barat, serta Brebes, Jawa Tengah. Pengujian aktivitas meliputi uji antagonisme dan karakterisasi aktivitas biokontrol (produksi enzim protease, kitinase, selulase, siderofor, hidrogen sianida, ammonia, peroksidase dan aktivitas katalase) secara in vitro. Identifikasi isolat bakteri agen biokontrol dengan dilakukan gen 16S rRNA dan dilanjutkan dengan pembuatan rekonstruksi pohon filogenetik. Berdasarkan hasil penelitian, diperoleh 5 isolat rizobakteri (I-8, L1-9, L1-12, BM-L3(2), dan BM-L3(3)) yang memiliki kemampuan antagonis terhadap patogen Pantoea sp. penyebab penyakit hawar daun bakteri pada bawang merah. Kelima isolat tersebut menunjukkan hasil positif pada uji aktivitas enzim protease, kitinase, selulase, siderofor, hidrogen sianida, ammonia, peroksidase dan aktivitas katalase. Hanya isolat BM-L3(2) yang tidak memiliki kemampuan dalam produksi enzim kitinase. Isolat BM-L3(2) dan BM-L3(3) teridentifikasi sebagai Brevibacillus schisleri dan Bacillus sp., sedangkan isolat I-8, L1-9, dan L1-12 teridentifikasi sebagai Streptomyces rochei berdasarkan sifat morfologi, analisis sekuens 16S rRNA, dan kekerabatan pada hasil rekonstruksi pohon filogeni.

Shallot (Allium ascalonicum L.) is vegetable commodity that has the threat of bacterial leaf blight caused by Pantoea sp. in its production. Utilization of biocontrol agents from bacteria associated with plant roots has high potential to produce pathogen inhibition mechanisms in plants. This research aims to obtain bacterial isolates of biocontrol agents that are able to inhibit the growth of Pantoea sp., study the characterization and mechanism activity of biocontrol agents, and identify bacterial of biocontrol agents. Bacterial of biocontrol agent candidates were isolated from root soil of shallot plants in Cirebon, Majalengka, and Brebes. The activity of the antagonism and biocontrol charaterization (enzyme production of protease, chitinase, cellulase, siderophore, HCN, ammonia, peroxidase and catalase) was tested by in vitro. Identification of biocontrol agent bacterial with the 16S rRNA gene was carried out and continued with phylogenetic tree reconstruction. Based on the results of the study, 5 rhizobacterial isolates (I-8, L1-9, L1-12, BM-L3(2), and BM-L3(3)) were obtained that have antagonism activity as biocontrol agent bacteria against the pathogen Pantoea sp. causing bacterial leaf blight in shallots. The five isolates showed positive results in the enzyme activity tests of protease, chitinase, cellulase, siderophore, hydrogen cyanide, ammonia, peroxidase, and catalase. Only isolate BM-L3 (2) does not have the ability to produce chitinase enzyme. Isolates BM-L3(2) and BM-L3(3) were identified as Brevibacillus schisleri and Bacillus sp., while isolates I-8, L1-9, and L1-12 were identified as Streptomyces rochei based on morphological characters, 16S rRNA sequence analysis, and kinship on phylogeny tree reconstruction results."
