"Bacteria in agrobiology : plant probiotics, discusses the current trends and future prospects of beneficial microorganisms acting as probiotics. Topics include the application for the aboveground fitness of plants, in mountain ecosystems, in tropical and Mediterranean forests, and in muga sericulture. Further aspects are Arabidopsis as a model system for the diversity and complexity of plant responses, plant parasitic nematodes, nitrogen fixation and phosphorus nutrition."

"This book will interest specialists dealing with cancer associated infectious complications, researchers working in the field of cancer biology, teachers and scientists in the field of microbiology, biotechnology, medicine and oncology. The unique coverage of bacteriology and cancer association in both positive and negative way can usher into development of novel thrust area for microbiology students and experts."

"Several novel aspects of extremophiles are covered in this book, the focus is firstly on unusual and less explored ecosystems such as marine hypersaline deeps, extreme cold, desert sands, and man-made clean rooms for spacecraft assembly. Secondly, the increasingly complex field of applications from extremophile research is treated and examples such as novel psychrophilic enzymes, compounds from halophiles, and detection strategies for potential extraterrestrial life forms are presented."

"This book explores direct fed microbial and prebiotic additives used in domestic animals, reviews questions that remain about how and why probiotic products work and which kinds are best for specific production scenarios and proposes areas for new research. "

"Saluran pencernaan merupakan organ-organ yang banyak dihuni oleh mikrobiota. Hubungan antara mikrobiota dan sel hospes memiliki dampak pada potensi metabolisme, kekebalan tubuh, serta respon neuroendokrin. Penelitian sebelumnya berhasil mengisolasi bakteri dari sampel mekonium, tiga diantaranya memiliki potensi probiotik seperti Bacillus subtilis MBF-30, Enterococcus hirae MBF-93, dan Staphylococcus hominis MBF-54. Tujuan dari penelitian ini adalah merancang proporsi galur-galur dalam koktail bakterial dan menganalisis kemampuan hidup galur-galur bakteri dalam suatu koktail, serta mengetahui proporsi masing-masing bakteri dalam suatu koktail dengan variasi waktu inkubasi. Analisis kemampuan hidup bersama setiap galur bakteri dilakukan dengan metode cross-streak. Hasil menunjukkan bahwa antar galur-galur bakteri mampu hidup bersama dalam koktail dengan tidak adanya zona hambat yang bermakna. Analisis kuantitatif dilakukan dengan menggunakan Real Time qPCR. Hasil analisis menunjukkan masing-masing bakteri dalam rancangan koktail bakteri Bacillus subtilis MBF-30, Enterococcus hirae MBF-93, dan Staphylococcus hominis MBF-54 berada dalam kondisi viabel pada waktu inkubasi jam ke-4, dan dengan perbandingan mendekati proporsional yaitu 1:0,75:0,5 dengan nilai kopi DNA/ml Bacillus subtilis MBF-30 adalah 9.0657e+11 log kopi DNA/ml, Enterococcus hirae MBF-93 adalah 1.7286e+17, dan Staphylococcus hominis MBF-54 adalah 2.167e+18.

Gastrointestinal tract is the most organ inhabited by microbiota. Interaction between microbiota and host cell has an impact in potencial metabolism, immune, and neuroendocrine responses. Previous studies have succeeded in isolating of the bacterial microbiota from meconium samples, three of which have probiotic potential such as Bacillus subtilis MBF-30, Enterococcus hirae MBF-93, and Staphylococcus hominis MBF-54. The aim of this study was to design of strain proportion in a bacterial cocktails, analyze viability of bacterial strains in cocktail condition, and determine the proportion of each bacterial strain in cocktail with variations incubation time. Analysis of the ability of each bacterial strain was carried out using cross-streak method. The result showed that each bacterial strains were able to coexist in cocktails with the absence of inhibition zone. Quantitative analyze was performed using Real Time qPCR. The results of analysis showed that each bacterial in cocktail bacterial Bacillus subtilis MBF-30: Enterococcus hirae MBF-93: Staphylococcus hominis MBF-54 was in viable condition at the incubation time of 4 hours, and with proportional ratio 1:0.75:0.5 with the value of DNA copy/ml Bacillus subtilis MBF-30 is 9.0657e+11 log DNA copy/ml, Enterococcus hirae MBF-93 is 1.7286e+17, and Staphylococcus hominis MBF-54 is 2.167e+18."
