Chitinase Activity Production by Planktonic, Benthic and Epiphytic Bacteria Inhabiting the Moty Bay of the Jeziorak Lake (Poland)
نویسندگان
چکیده
A study on the occurrence and chitinolytic activity of planktonic, benthic and epiphytic bacteria was carried out in the Moty Bay of Lake Jeziorak near Ilawa. The greatest number of chitinolytic bacteria occurred on macrophytes. In terms of percentages, the chitinolytic bacteria share among heterotrophic bacteria was much greater in epiphytic and planktonic bacteria than in benthic ones. When confronted with colloidal chitin, all the investigated strains showed maximum chitinolytic activity after 96 h incubation and the minimum after 48 hours. The greatest total chitinase activity was recorded in planktonic bacteria, while specific activity in epiphytic bacteria.

Occurrence of Chitinolytic Bacteria in Water and Bottom Sediment of Eutrophic Lakes in Iławskie Lake District
A study was carried out on the occurrence of chitinolytic bacteria inhabiting surface water, water above the sediment and bottom sediments of lakes: Jeziorak, Jeziorak Maty and Tynwald. The greatest amounts of them were found in demersal water and in bottom sediment surface stratum. However, the percentage share of chitinolytic bacteria proved greater in deep water (9.35%) than in bottom sedime...
متن کاملAntibiotic Sensitivity of Neustonic Bacteria in Lake Jeziorak Mały
This paper presents the results of research on the antibiotic sensitivity of bacteria inhabiting the surface microlayer (SM) and the subsurface water (SSW) of Lake Jeziorak Mały. It follows from the results that doxycycline, oxytetracycline and nalidixic acid are characterized by the strongest antibacterial effect. For some antibiotics, different strengths of the effect on bacteria isolated fro...
متن کاملProduction of Cytokinin-like Substances by Planktonic Bacteria Isolated from Lake Jeziorak
Studies on cytokinin-like substances synthesized by planktonic bacteria isolated from littoral and pelagial zones of lake Jeziorak in spring and summer have been carried out. 62.5% of bacteria isolated in summer, and 12.5% of bacteria isolated in spring were able to produce cytokinin-like substances. Among synthesized substances we found isopentenyladenine (2iP, iAde), zeatin (Z, ioAde) and zea...

Bacterial abundance, production, and extracellular enzyme activity were determined in the shallow water column, in the epiphytic community of Thalassia testudinum, and at the sediment surface along with total carbon, nitrogen, and phosphorus in Florida Bay, a subtropical seagrass estuary. Data were statistically reduced by principle components analysis (PCA) and multidimensional scaling and rel...
متن کاملAromatic Hydrocarbon Decomposition by Neustonic Bacteria Part I. Single-ring Hydrocarbon Biodegradation
The present paper provides an account of a study on benzene, toluene and xylene degradation by neustonic and planktonic bacteria in lake Jeziorak Maty. Aromatic hydrocarbons were better decomposed by neustonic bacteria than planktonic bacteria. Moreover, the obtained data point to the total number of bacteria and heterotrophic bacteria number being greater in surface microlayer than in subsurfa...
