PURPOSE: A natural antibiotic produced by absorbing microorganisms to powder is provided to maximize the function of the antibiotic by adding humic acid to the powder. CONSTITUTION: A natural antibiotic is obtained by absorbing more than one microorganism selected from bacillus cereus or bacillus firmus to powder. The natural antibiotic additionally contains humic acid. The powder contains 52-53% of silicon oxide, 14-16% of oxide aluminum, 10-11% of ferric oxide, 0.5-1% of titanium oxide, 3-4% of calcium oxide, 6-7.5% of magnesium oxide, 6-7% of potassium oxide, and 2-3% of sodium oxide. 1kg of powder additionally contains 20-30mg of cobalt, 15-20mg of germanium, and 20-25mg of selenium.본 발명은 천연항생제에 관한 것으로, 보다 상세하게는 산화규소, 산화알미늄, 산화철, 산화티타늄, 산화칼슘, 산화마그네슘, 산화칼륨, 산화나트륨, 코발트, 게르마늄 및 셀레늄을 포함하는 분말에 바실러스 세레우스(Bacillus cereus) 또는 바실러스 퍼머스 중에서 선택되는 하나 이상의 미생물을 흡착시킨 천연항생제에 관한 것이다.
