ABSTRACT Four sponge-associated Antarctic bacteria (i.e., Winogradskyella sp. strains CAL384 and CAL396, Colwellia strain GW185, Shewanella CAL606) were selected for the highly mucous appearance of their colonies on agar plates. The production extracellular polymeric substances (EPSs) was enhanced by a step-by-step approach, varying carbon source, substrate NaCl concentrations, temperature, pH. EPSs produced under optimal conditions chemically characterized, resulting in moderate...
Sea environments harbor a wide variety of life forms that have adapted to live in hard and sometimes extreme conditions. Among the marine living organisms, extremophiles represent group microorganisms attract increasing interest relation their ability produce an array molecules enable them thrive almost every environment. Extremophiles can be found virtually environment on Earth, since they tolerate very harsh environmental conditions terms temperature, pH, pressure, radiation, etc. Marine...
In the present work recently isolated strain Basfia succiniciproducens BPP7 was evaluated for production of succinic acid up to pilot fermentation scale in separate hydrolysis and experiments on Arundo donax, a non-food dedicated energy crop. An average concentration about 17g/L yield consumed sugars 0.75mol/mol were obtained demonstrating potential further process improvement. Small indicated that acetic medium is crucial improve productivity; other hand, interestingly, short-term (24h)...
An extremely halophilic archaeon belonging to the order Halobacteriales was isolated from Fuente de Piedra salt lake, Spain. This strain, designated FP1 T , a pleomorphic coccoid, neutrophilic and required at least 15 % (w/v) NaCl for growth. Strain grew 37–60 °C, with optimal growth 50 °C. Mg 2+ not required, but observed up 10 MgSO 4 . Polar lipid analysis revealed presence of mannose-6-sulfate(1-2)-glucose glycerol diether as major glycolipid. Both C 20 25 core lipids were present. The...
Waste biomass coming from a local coffee company, which supplied burnt ground after an incorrect roasting process, was employed as starting material in the composting plant of Experimental Station University Naples Federico II at Castel Volturno (CE). The direct molecular characterization compost using 13C-NMR spectra, acquired through cross-polarization magic-angle spinning, showed hydrophobicity index 2.7% and alkyl/hydroxyalkyl 0.7%. Compost samples that were collected during early...

Abstract Marinobacter sp. W1-16 from Antarctic surface seawater was analysed for the production of extracellular polymeric substances (EPSs). Enhancement EPS biosynthesis carried out by evaluating influences carbon source (type and concentration), temperature, pH salinity. yields varied strongly depending on sugar substrate while salinity did not affect levels production. produced highest quantity EPSs when growing at 15°C 8, in presence 2% glucose 3% NaCl. The chemical characterization...
A Gram-positive, spore-forming, halophilic bacterial strain, FP5T, was isolated from a salt lake in southern Spain and subjected to polyphasic taxonomic study. Strain FP5T strictly aerobic. Cells were coccoidal, occurring singly or clusters. The cell-wall peptidoglycan type of strain A4β based on l-Orn–d-Asp. characterized chemotaxonomically by having MK-7 as the major menaquinone anteiso-C15 : 0, anteiso-C17 iso-C15 0 iso-C16 main fatty acids. isolate grew optimally at 37 °C presence 10 %...
A Gram-stain-positive, non-endospore-forming, haloalkaliphilic actinobacterium, strain CK5T, was isolated from a soil sample, collected at Cape King (Antarctica), and its taxonomic position investigated by using polyphasic approach. Cells were cocci with orange pigmentation, non-motile grew optimally 25 °C pH 9.0-9.5 in the presence of 2 % (w/v) NaCl. Cellular membrane contained MK-7 (72 %) MK-8 (28 %), anteiso-C15 : 0 (64.8 iso-C16 (13.3 n-C17 (9.9 n-C16 (4.0 n-C14 (3.7 as major cellular...
Among plant polyphenols, lemon peels extract (LPE) from the residues of industrial processing (Citrus limon) shows anti-proliferative properties in cancer cells and anticholinesterase activity. In this study, we analyze anti-cancer LPE on migration invasiveness MKN-28 AGS human gastric cell lines either absence or presence pro-inflammatory cytokine IL-6. We find that pretreatment with non-cytotoxic concentrations (0.5–1 μg/ml gallic acid equivalent) inhibits interleukin-6 (IL-6)-induced...
Pseudomonas strain 2ASCA isolated in subarctic Québec, Canada, produced a cell membrane bound levan-type exopolymer (yield 1.17 g/L), after incubation growth media containing 6 % sucrose (w/v) at temperature of 15 °C for 96 h. The objective this study was to optimize levan production by varying the parameters. Moreover, polymer's chemical characterization has been studied with aim increasing knowledge and leading future applications many fields, including heavy metal remediation. Higher...
A Gram-stain-positive, aerobic, endospore-forming, thermophilic bacterium, strain N.8T, was isolated from the curing step of an olive mill pomace compost sample, collected at Composting Experimental Centre (CESCO, Salerno, Italy). Strain based on 16S rRNA gene sequence similarities, most closely related to Aeribacillus pallidus H12T (=DSM 3670T) (99.8 % similarity value) with a 25 DNA-DNA relatedness value. Cells were rod-shaped, non-motile and grew optimally 60 °C pH 9.0, forming cream...
