Isolation and Characterization of Polygalacturonase Produced by Tetracoccosporium sp.
Thirty-five fungal strains which isolated from vegetable wastes, were screened for the use of polygalacturonic acid as the sole carbon source. Twenty-five isolates were positive for polygalacturonase activity in cup-plate assay, as evidenced by clear hydrolysation zones. The most productive strain was determined by measuring clear zones formed around colonies stained with ruthenium red.</em...
متن کاملPurification and biochemical characterization of polygalacturonases produced by Aureobasidium pullulans.
The extracellular polygalacturonases produced by Aureobasidium pullulans isolated from waters of the Danube river were partially purified and characterized. The pH optima of polygalacturonases produced in the first phases of cultivation (48 h) and after 10 d as well as their optima of temperature, thermal stabilities, molecular masses, isoelectric points, action pattern and ability to cleave po...
متن کاملCharacterization of an Exopolymeric Flocculant Produced by a Brachybacterium sp.
We evaluated the bioflocculant production potential of an Actinobacteria, which was isolated from a freshwater environment in the Eastern Cape province of South Africa. 16S rDNA nucleotide sequencing analyses revealed that the actinobacteria belongs to the Brachybacterium genus, and the sequences were deposited in the GenBank as Brachybacterium sp. UFH, with accession number HQ537131. Optimum f...

متن کاملCharacterization of a Bioflocculant Produced by a Consortium of Halomonas sp. Okoh and Micrococcus sp. Leo
The physicochemical and flocculating properties of a bioflocculant produced by a bacterial consortium composed of Halomonas sp. Okoh and Micrococcus sp. Leo were investigated. The purified bioflocculant was cation and pH dependent, and optimally flocculated kaolin clay suspension at a dosage of 0.1 mg/mL. The flocculating activity of the bioflocculant was stimulated in the presence of Ca2+, Mn2...
