Proteolytic activities of bacteria, yeasts and filamentous fungi isolated from coffee fruit (Coffea arabica L.)
One hundred forty-four microorganisms previously isolated from coffee fruit (Coffea arabica) were grown on casein agar to evaluate their proteolytic activities. Fifty percent of filamentous fungi, 52.5% of bacteria and 2.6% of yeasts were able to secrete proteases. Positive isolates were further examined in liquid culture for their protease activities by hydrolysis of casein at different pH val...
متن کاملBiofilm formation and proteolytic activities of Pseudoalteromonas bacteria that were isolated from fish farm sediments
In order to save natural resources and supply good fishes, it is important to improve fish-farming techniques. The survival rate of fish fry appears to become higher when powders of foraminifer limestone are submerged at the bottom of fish-farming fields, where bacterial biofilms often grow. The observations suggest that forming biofilms can benefit to keep health status of breeding fishes. We ...
متن کاملAntibacterial Activities of Extracellular Metabolites of Symbiotic Bacteria, Xenorhabdus and Photorhabdus Isolated from Entomopathogenic Nematodes
Xenorhabdus and Photorhabdus are members of the family Enterobacteriaceae, and are engaged in a mutualistic association with the entomopathogenic nematodes, Steinernema and Heterorhabditis, respectively. In the present study, the organic fraction of ethyl acetate bacterial crude extracts of the symbiotic bacteria, Xenorhabdus stockiae and Photorhabdus luminescens isolated from entomopathogenic ...
متن کاملAntioxidant, lipolytic and proteolytic enzyme activities in pork meat from different genotypes.
Oxidative processes in meat lead to meat quality deterioration. Meat has endogenous antioxidants and prooxidants, but information on factors influencing the activity of antioxidant enzymes in meat is limited. Lipolytic and proteolytic enzymes are involved in important aspects of meat quality. Our objective was to find differences between five different genotypes on the activity of antioxidant, ...
متن کاملInhibitory effect against pathogenic and spoilage bacteria of Pseudomonas strains isolated from spoiled and fresh fish.
The antibacterial effects of 209 Pseudomonas strains isolated from spoiled iced fish and newly caught fish were assessed by screening target organisms in agar diffusion assays. One-third (67 strains) inhibited the growth of one or several of six target organisms (Escherichia coli, Shewanella putrefaciens, Aeromonas sobria, Pseudomonas fluorescens, Listeria monocytogenes, and Staphylococcus aure...
