Possible correlation between levansucrase production and probiotic activity of Bacillus sp. isolated from honey and honey bee

African catfish (Clarias gariepinus) is a popular fish in the community because it provides a high level of protein at a low cost. The motile aeromonas septicemia (MAS) disease produced by Aeromonas hydrophila (A. hydrophila) infection is one of the things that create difficulties in the cultivation of this fish. Synthetic antibiotics are commonly used in MAS disease control management efforts in fish farming, which have have an influence not only on fish but also on consumers. The application of probiotic Bacillus sp isolated from the digestive tract of catfish as a means of preventing the sickness is one option. Enzymatic tests (lipolytic, amylolytic, cellulolytic, proteolytic activity) and antagonist testing were used to assess the probiotic activity of the Bacillus sp isolates.

Probiotic Activity

Intensive shrimp culture has encountered many problems, such as declining water quality through disease caused by pathogenic microbes, which affected mortality. This study aimed to determine any potential probiotic from Bacillus sp. collected from mangrove in East Lampung, which could be used to improve the cultured shrimps' proteolytic and probiotic activity. This is a descriptive research with sampling and data collection of bacteria from many samples of mangrove. Result shows 128 isolates Bacillus from which then it has arrived at five potential probiotic Bacillus sp. The study five Bacillus sp. has been isolated with potential properties for probiotic (KPP212, IP121, UJ131, UJ132, SB141). Each isolate has characteristics with proteolytic property, growth in a wide range of pH 4–10 and osmotic stress (0–6% NaCl), non-pathogenic, ability for glucose fermentation, non-motile, and has negative catalase activity. The five potential Bacillus sp. can be used as probiotics for shrimp farming.

Honey Bee Larvae

European foulbrood is a bacterial disease that affects Western honey bee larvae. It is a concern to beekeepers everywhere, though it is less serious than American foulbrood because it does not form spores, which means that it can be treated. This 7-page fact sheet written by Catherine M. Mueller, Cameron J. Jack, Ashley N. Mortensen, and Jamie Ellis and published by the UF/IFAS Entomology and Nematology Department describes the disease and explains how to identify it to help beekeepers manage their colonies effectively and prevent the spread of both American and European foulbrood.https://edis.ifas.ufl.edu/in1272

МЕЛИКИДИ В.Х., ТЮРИНА Д.Г., СЕЛИВАНОВ Д.Г., НОВИКОВА Н.И. ООО «БИОТРОФ», Санкт-Петербург Аннотация: Приведены данные исследования методом газожидкостной хроматомасс-спектрометрии метаболитов, синтезируемых пробиотическими бактериями, входящими в состав кормовой добавки «Профорт®». Проведен опыт в условиях интенсивного промышленного птицеводства по применению кормовой добавки «Профорт®» (50 тыс. голов бройлеров в группе). Среди метаболитов пробиотических штаммов Enterococcus sp. и Bacillus sp. обнаружены такие полезные вещества, как молочная кислота, уксусная, пропионовая и другие короткоцепочечные (летучие) жирные кислоты, активные пептиды. Результаты зоотехнического опыта показали, что при скармливании бройлерам пробиотика «Профорт®» (500 г/т) живая масса при убое в 40 дней была выше контроля на 6,9%, конверсия корма улучшилась на 3,0%, а европейский индекс продуктивности бройлеров - на 5,69%.
