The bacterium Microbacterium aurum strain B8.A degrades granular starches, using the multi-domain MaAmyA α-amylase to initiate granule degradation through pore formation. This paper reports the characterization of the M. aurum B8.A MaAmyB enzyme, a second starch-acting enzyme with multiple FNIII and CBM25 domains. MaAmyB was characterized as an α-glucan 1,4-α-maltohexaosidase with the ability t...

The actinobacterium strains were isolated from marine samples that collected from South Sinai Sharm ElSheikh, Egypt. These isolates were screened for antimicrobial activities in starch nitrate medium. One of the actinomycete isolates (Askar-SH50) was found to produce a broad spectrum antimicrobial activity. Identification of the most potent isolate was performed according to the cell wall chemo...

search for novel antimicrobial agents from microorganisms, an actinomycete strain Streptomyces sp. isolated from a soil sample collected in Taejon, Korea, was found to produce a new antibacterial 16-methyloxazolomycin (1). In this paper, we describe the production, isolation, structural elucidation and biological activities of 1. The strain was cultured in the seed mediumconsisting of glucose 2...

Brachybacterium sp. strain LB25 produces a maltooligosaccharide-forming amylase that improves product selectivity in water-miscible organic solvents. The enzyme hydrolyzed starch to produce maltotriose primarily. The structural gene encoding the amylase from strain LB25 was cloned and sequenced. The amino acid sequence of the product showed significant similarity (45 to 49%) to amylases from th...

The application of an HPLC bioactivity profiling/microtiter plate technique in conjunction with microprobe NMR instrumentation and access to the AntiMarin database has led to the isolation of a new 1. In this example, 1 was isolated from a cytotoxic fraction of an extract obtained from marine-derived Streptomyces sp. cultured on Starch Casein Agar (SCA) medium. The 1D and 2D (1)H NMR and ESIMS ...

An isolate, KC46 active against clinical resistant strains was isolated from Indian soil. Based on morphological features and biochemical characteristics it was identified as Streptomyces noursei. The active compounds isolated from KC46 using various fermentation methods (fermentation in shake flasks, in P-flasks, and also in a fermenter, using starch casein nitrate medium containing zinc sulph...

The aim of current study was to test the ability and optimize decolorization textile azo Reactive Orange 122 by Streptomyces sp (A5) isolated from dye contaminated soil. isolate assessed spectrophotometer at 3, 5 7 days in starch nitrate broth media amended with 0.35 g/L dye. Different incubation conditions like concentration dye, temperature pH were used present investigate their effect on rat...

Ham Yen orange (Citrus nobilis Lour) is the highly valuable commercial fruit of Vietnam. With the blooming of fruit production and farming area, this specialty crop is facing threats from several serious diseases; therefore the search for new effective biocontrollers is required to prevent the existing excessive use of fertilizers and plant protection chemicals. Endophytic actinomycetes are of ...

temperature was 27°C. On International Streptomyces Project (ISP) media 1, 2, 3, and 5, the strain produced yellow diffusible pigment and the reverse side color of the colonies was yellow. Melanin production was not observed on either tyrosine or peptone iron agar. The following tests were positive: starch hydrolysis; degradation of allantoin, lecithin, pectin, xanthine, and hypoxanthine; resis...
