The culture of bioinsecticide containing active Bacillus thuringiensis H-14 local strain on various kinds on coconut water pH and its toxicity against Aedes aegypti and Anopheles aconitus were carried out in the laboratory on Institute of Vector and Reservoir Control Research and Development Salatiga. The objectives of this study were : To determine the optimum pH from various kinds of coconut …
A study was conducted to determine 1) The optimum of pH coconut water for proliferation cell and spore B. Thuringiensis H-14 local strain 2) The LC50 (Lethal concentration 50%) and LCR95 Ae aegypti dan An. Aconitus mosquito larvae from various kind of coconut water for 24 testing 3). The measure contents of nutrition (carbohydrate, fat protein and reduced glucose) coconut water for profiferatio…
A research on the effect of traditional legundi leaves extract against Bacillus subtilis, Escherichia coli and Salmonella typhi has been done. Leaves of legunfi were tested for recovering of some diseases i.e. malnutrition, stiff of stomach, cough, injury, tonsil inflammation, child’s fever, whooping cough, and tuberculosis, however supports of scientific data was not satisfactory. B. subtili…
The isolation and characterization of chromosomal genes and bacterial plasmids are important for strain improvement to produce most valuable compounds on industrial scale. The isolation of the neutral protease (npr) fragment from Bacillus megaterium was carried out by polymerase chain reaction (PCR). The PCR experiments were done setting up of variation for oligonucleotide primers, annealing te…
A study was conduced using local strain of Bacillus thuringiensis H-14 which was culture in a rice washed water in Institute for Vektor and Resevoir Control Research Development (IVRCRD) Salatiga. The aim of this study was to determine the pathogenicity of the local strain of B. thuringiensis H-14 against Anopheles aconitus and Aedes aegypti third instar larvae. The pathogenicity test was condu…
Probiotic bacteria have a beneficial effect on diarrhea. In this study, we have examined effect of Lactobacillus plantarum Strain IS-10506 (LIS-10506) and I-20506 (LIS-20506) on inhibition of NF-kB activation, downregulation TNF Receptor-1 (TNF-RI) and Apoptosis in Epithelial Brush Border of Rattus novergicus per oral. At the 3rd day, Lactobacillus plantarum Strain IS-10506 and LIS20506 separat…
