Rice straw is a byproduct formed during rice cultivation. Disposal of may happen via unhygienic methods such as burning, which happening in Malaysia and other countries. This study aims to rid an eco-friendly biodegradation technique. Biodegradation depended on actinobacteria, were isolated from the cultivated soil rhizosphere areas Tabuk region. Out thirty actinobacterial isolates, only three ...

Since first isolated from the lipophilic extract of Streptomyces sp. SF2583, streptochlorin, has attracted a lot of attention because of its various pharmacological properties, such as antibiotic, antiallergic, antitumor, and anti-inflammatory activities. For the efficient preparation of streptochlorin from a producing strain Streptomyces sp. SYYLWHS-1-4, we developed a combinative method by us...

Streptomyces has been known as a source of natural bioactive substances so far. In this present study, the sponge-derived HM9 was optimised with number different carbon (C) and nitrogen (N) sources to evaluate broad-spectrum antibacterial ability. Starch (NH4)2SO4 were favourable growth strain HM9. casein suitable for activity against Vibrio, whereas lactose NH4Cl beneficial on inhibition stand...

BACKGROUND & OBJECTIVE Dermatophytes responsible for causing dermatophytoses in humans have acquired resistance to certain antimycotic drugs. We isolated naturally occurring actinomycetes with an ability to produce metabolites having antimycotic property. The timecourse of antifungal metabolite production in terms of arbitrary units (AU) under optimum conditions was studied. METHODS Water and...

Since the marine environmental conditions are extremely different from the other ones, marine actinomycetes might produce novel bioactive compounds. Therefore, actinomycete strains were screened from marine water and sediment samples collected from the coastal areas of Northern Vietnam. Ninety-nine actinomycete strains were obtained on starch-casein agar media by dilution technique, only seven ...

In order to seach for different microbial sources of enzymes, Arthrobacter polychromogenes CDPI-30 and Streptomyces violaceoruber CDPA-32 were individually cultivated in licuri [Syagrus coronata - (Martius) Beccari] residues. It was possible detect some enzymes but amylase, lipase xylanase selected a basic characterization. The optimum conditions observed at pH 6 7 40 – 70 °C amylases, 4 50 90 ...

The Buyeo Royal Tomb No. 1 is an ancient tomb built in the late 6th and early 7th century. four walls of main room have murals guardian deities, ceiling has lotus cloud patterns. This study assessed optimal growth conditions two fungal (Fusarium oxysporum, Mortierella sp.) bacterial (Bacillus cereus, Cupriavidus campinensis, Streptomyces avidinii, cirratus) strains isolated from 1, along with t...

Streptomyces clavuligerus is a member of the Actinobacteria family primarily known for its production clavulanic acid antibiotic. The need identification new antimicrobials led to volatile components S. metabolites using GC-MS. isolate was obtained from Ocimum gratissimum rhizosphere starch casein agar, and identified molecular typing. preliminary antibacterial screening carried out some indica...

In this study, the antagonistic effect of five bacteria genera namely Bacillus, Pseudomonas, Azotobacter, Azospirillum, and Streptomyces isolated from rhizosphere wheat were evaluated against Fusarium graminearum as potential biocontrol agents in vitro. F. was molecularly diagnosed using Polymerase chain reaction (PCR) technique. Each tested for production catalase enzyme, oxidase analysis star...
