چکیده

hyaluronidase has a panoramic use in biotechnology processes and therapy due to its therapeutic, pathophysiological, physiological and biological importance. since much of the preparations of hyaluronidases are from animal source (bovine and ovine testicular sources) with limited sources of microbial origin, that prompted the authors to screen and isolate a new promising bacterial strain with higher yield followed by its characterization employing detailed taxonomic studies. the newly isolated strain was identified based upon their micro- and macro-morphological, cultural, physiological and biochemical parameters. twenty isolates from different pathological samples were primarily selected and further screened for their hyaluronidase producing capabilities by measuring reduction in turbidity and hydrolyzed zone of substrate hyaluronic acid. four isolates showing marked reduction in turbidity (a600 nm) and hydrolyzed zones were selected and subjected to secondary screening by shake flask fermentation. isolate sii9 (dental caries specimen) exhibited maximum hyaluronidase activity (117 u/ml) when compared to the reference streptococcus mitis mtcc*2695 (106 u/ml). a close scrutiny of the literature revealed that the characteristics of our isolate sii9 are mostly identical to s. equi subsp. equisimilis with few differences and thus designated as s. equi sed 9.

Screening and Isolation of Extracellular Protease Producing Bacteria from the Maharloo Salt Lake

      Screening and identification of moderately halophilic protease producing bacteria from different regions of Maharloo, a hypersaline lake in the southern area of Iran, were the objectives of this study. In the preliminary screening, 16 isolates exhibited proteolytic activity on saline skim milk agar. All isolates were able to grow comfortably in the media containing 7-15% of salt. Protease...

Screening and isolation of halophilic bacteria producing industrially important enzymes

Halophiles are excellent sources of enzymes that are not only salt stable but also can withstand and carry out reactions efficiently under extreme conditions. The aim of the study was to isolate and study the diversity among halophilic bacteria producing enzymes of industrial value. Screening of halophiles from various saline habitats of India led to isolation of 108 halophilic bacteria produci...

Isolation and molecular identification of carotenoid-producing bacteria

The production of pigments from bacteria is significant due to the low cost, high yield and ease of extract compared with other sources. Carotenoids are one of the most important pigments with antioxidant properties which are the precursor of vitamin A synthesis and have antibody overproduction ability, anti-tumor activity and inhibitory effect on the cardiovascular disease. The present study a...

Isolation, screening and characterization of bacteriocin-producing lactic acid bacteria isolated from traditional fermented food.

100 lactic acid bacterial strains isolated from traditional fermented foods (yoghurt, milk cream, sour dough and milk) were screened for bacteriocin production. Twenty six strains producing a nisin-like bacteriocin were selected. Most of these isolates gave only a narrow inhibitory spectrum, although one showed a broad inhibitory spectrum against the indicator strains tested, this strain was de...
