At present, there are many kinds of microorganisms that live in the soil And play important roles in its application in various fields The agriculture, industry, the separation and screening of microorganisms that can produce the enzyme protease from the soilThe study on isolation and screening of microorganisms from soil at home mom huak, double house, Ko Kha District, I hope, Lampang and squat cascading waterfall National Park Mueang Yang District school were isolated and screening microbes(Serial Ten-Fold dilution) suitable 3 level. To spread spread plate on medium skim milk agar incubated at 37 degrees Celsius For 24 hours, then use Loop tap different colonies by looking at the differences of colonies appear streakTrytic Soy Broth Agar curing temperature 37 C until the re-streak pure culture The microorganism isolated pure gross test enzyme production by way of design, point inculation cultureSkim milk agar incubated at 37 C time 24 hours. Then brought measuring diameter of clear by infection The 29 isolates are bacteria infections MH2-4Pro was born Clear large Zone is 9002A mm
From the morphological characteristics found Gram positive bacteria isolates were 21 infections Isolates with Gram negative bacteria were 8 infections, cellular morphology bacteria a bar (Rot) were 22 infections. Part Short rot (picture) The 4 infections(Coccus) were 3 infections
