Abstract

ABSTRACTExploration of Soil Actinomycetes Diversity from Ternate as Indigenous Antibiotic Sources.Actinomycetes of soil samples from Ternate, North Moluccas were isolated using SDS-YEmethod in humic acid vitamin agar. Ternate has high abundance of Actinomycetes, approximately6.00 – 487 x 104 CFU/ g soil, depends on habitat types. We have selected 60 isolates andconducted antibiotic screening against pathogenic bacteria and fungi using agar diffusionmethod and found both narrow and broad antibiotic spectrum types . Based on 16S rDNAanalysis, all Actinomycetes with antibiotic activities are belong to the genus Streptomyces. .Minimum Inhibitor Concentration (MIC) value was determined by broth microdilution method.It was found that MIC values varied, depended on microbial tested. We found two isolateswith higher antibiotic activity compared to the commercial antibiotics (chloramphenicol,erythromycin for antibacterial and nystatin, kabicidin for antifungal). Cell destruction analysiscaused antibiotic activities was conducted through leak of protein and nuclatic acid.Key words : Actinomycetes, soil, Ternate, antibiotic, cell distruction

Abstract

ABSTRACTThe objectives of study were to identify antimicrobial producing Actinomycetes using 16S rDNA analyses and morphology and physiology characteristics. Eight Actinomycetes strain with the higest antibacterial and antifungal activity were selected and identified using six primers (20F, 520F, 920F, 1500R, 920R, and 520R). Morphological observation and physiology analyses were performed to the selected strain to accurately identify the strains. Morphological characters observed were aerial mycelium, spore chain, colony form, and pigment production. Physiological characterizations were antimicrobial properties, growth temperature, pH tolerance, salinity concentration for growth, sugars assimilation, and some enzymes production (arginine dihydrolase, urease, ß-glucosidase, protease, ß-galactosidase). Based on homology search by BLAST program and phylogenetic tree analyses, all of isolates were identified as the genus Streptomyces. They belong to eight different spesies. Isolates RC-SS-37-4, RC-SS-37-16 and BL-22-3 have been identified as Streptomyces costaricanus (100 %), Streptomyces costaricanus (99.8 %) and Streptomyces parvulus (98.6 %), respectively. Five isolates were identified as Streptomyces spp. (BL-36-1, BL-20-2, BL-14-2, BL-22-1 and BL-06-5) and can be presumed as new species because of the low homology value to their closest related spesies. Keywords : actinomycetes, antimicrobial, morphology, phylogenetic, physiology, 16S rRNA gene.

Abstract

ABSTRACTThe Abundance and Diversity of Soil Actinomycetes from Ciremai National Park West Java.Actinomycetes of soil samples from Mount Ciremai National Park, West Java were been isolatedby Sodium Dodecyl Sulphate Yeast Extract (SDS YE) method in Humic Acid Vitamin Agar(HVA) medium. The colonies of actinomycetes were counted based on Total Plate Count(TPC). Diversity of actinomycetes were identified based on spore, chain spore, pigmentation,hypha and aerial hypha formation. The abundance of actinomycetes were 3,50 x104 – 71,50 x104CFU/g soil. Seven genus of actinomycetes were found, they were Streptomyces, Nocardia,Micromonospora, Microbiospora, Actinomadura, Actinoplanes, and Microtetraspora. Mostof them were distributed in 900 until 2500 m height above sea level. Streptomyces only knownin 2700, 2900 and 3057 m above sea level. Population of Streptomyces were predominant in allsoil types according to height, but were highest in 2500 m asl.Key words: Actinomycetes, fungi, Mount Ciremai, diversity, abundance.

Abstract

ABSTRACTSoil Actinomycetes Population, Enzymes Activity, and its Relation with Carbon and NitrogenContent, in Bukit Bangkirai, East Kalimantan. Bukit Bangkirai is one of the tropical forest inIndonesia have been exposed with intense forest fire. The affected forest is subjectivelydivided into three level of damages, heavily damage forest (HD), low damage forest (LD) andcontrol (K). The objective of this research was to observe the abundance of Actinomyceteswhich have important role in ecological process. Through decompotition of organic materialsand nutriens cycle. Actinomycetes were isolated and enumerated by SDS-YE method. CFU/ gsoil (x 104) in K, HD and LD are 41,86 ± 25,52, 16,09 ± 5,70 and 18,96 ± 4,19 respectively. Amylaseand cellulase were determined by DNS method. Carbon and Nitrogen total were determinatedby CN analyzer. The different of amylase, cellulase activities and abundace of Actinomycetesbetween HD, LD, and Control plot were not significant. However, carbon and nitrogen totalare different. LD plot has the highest carbon and nitrogen total, followed by control and HDplot. There has no significant different among plot observed may indicate microbial communitiesof soil in Bukit Bangkirai have been recovered.Key words : actinomycetes, fire forest, amylase, cellulase, nitrogen total, carbon total
