Serum of mud crab, Scylla serrata had antibacterial activity against certain host specific bacteria as well as other known crustacean pathogenic bacteria. The respective antibacterial molecule was isolated by ion-exchange chromatographic method using diethylaminoethyl-cellulose matrix and eluted with gradient increase of sodium chloride (0–0.5 M). There were three major peaks on the elution profile...
In order to determine effects of different types of supplementary feed on the histology of liver and intestine of carp reared in a semi-intensive system, a six-month field experiment was carried out. Carp yearlings were fed different supplemental feeds: cereals (CF), pelleted (PF) and extruded (EF) compound feeds. Hepatocytes histomorphometry revealed larger nuclear profile area of EF-fed fish compared...
Ribosome-inactivating proteins (RIPs), a type of defensive chemicals, play key roles in host defense mechanisms against foreign pathogenic invaders and plant stress resistance. Alpha-momorcharin, a member of typical type I RIPs isolated from Momordica charantia, showed strongly antifungal, antitumor, and antibacterial activities both in vitro and in vivo. In this study, the expression level of alpha-momorcharin...
The essential oil composition and in vitro antioxidant activity of eight important betel vine landraces, such as Balia, Chandrakala, Dandabalunga, Desibangla, Godibangla, Karpada local, Maghai and Nahua were evaluated in this research. GC and GC-MS analysis of the essential oil resulted in identification of 50 compounds representing 95.97% of the oil. Major compounds were eugenol, terpinolene, terpinene,...
Natural dyes and pigments are emerged as an important alternative to potentially harmful synthetic dyes. There is a growing demand for eco-friendly/non-toxic colourants specifically for textile dyeing because of its sustainability, green chemistry and improved eco-balances. The present study aimed to evaluate the dyeing potential of violet pigment from Chromobacterium violaceum UTM5. Dye-ability of...
Study describes protocols for in vitro propagation of Gentiana utriculosa L. via axillary shoot multiplication and indirect somatic embryogenesis. Shoot cultures were established from seedling epicotyl explants cultured on MS medium supplemented with 0.25 mg L−1 BA and 0.1 mg L-1 IAA. Medium containing 2% sucrose and 0.2 mg L−1 BA improved multiple shoot production, providing 2.3 shoots per explant...
Living roots grow in soil, which is a heterogeneous environment containing a wide variety of physical barriers. Roots must avoid these barriers to grow: first, they adopt a characteristic S-shape that can be described by the angle between the root tip and the barrier (i.e., the tip-to-barrier angle); then, they move parallel to the barrier by keeping the sensitive tip in contact with the barrier until...
A specific and sensitive conventional and real-time PCR assays were developed for the detection and quantification of Rhizoctonia solani populations infecting pulses. Five different sets of R. solani specific molecular primers ARSF1&R1, ARSF2&R2 and ARSF3&R3, ARSF4&R4 and ARSF5&R5 were designed from the internal transcribed spacer sequences of R. solani isolates associated with...
The two-year dynamics of soil collembolan communities were studied at five sites along the mesoclimatic gradient in a deep karst valley, from the karst plateau to the bottom of the deep karst gorge in the Zádiel Valley, Slovak Karst, Slovakia. Within the local gradient the annual soil temperature means ranged from +8.88 ± 6.72°C on the plateau (pasture) to +5.16 ± 6.24°C at the bottom of the gorge...
Bromeliads accumulate water in the leaf axils (forming phytotelmata), which may then form a habitat for many animal species of both invertebrates and vertebrates. In temperate regions, bromeliads are commonly displayed in palm houses and distributed by florist wholesalers. Taking into account the fact that global plant trade can be a source of spreading alien species, the phytotelmata that had formed...
The earthworm genus Satchellius Gates, 1975 is reviewed. On the basis of the presence of posterolateral calciferous sacs in segment 10 the species Dendrobaena alvaradoi Moreno, Jesus & Diaz Cosin, 1982 and Dendrobaena madeirensis (Michaelsen, 1891) are transferred to the genus Satchellius as comb. novae. The specimens reported as Allolobophora madeirensis by Zicsi (1969) from Madeira Island (Portugal)...
In years 2010–2013, we collected mosquito larvae and adults at selected locations in Eastern Slovakia. We have identified 22 mosquito species belonging to 6 genera: Aedes (4 species), Anopheles (4 species), Coquillettidia (1 species), Culiseta (1 species), Culex (3 species) and Ochlerotatus (11 species), with eudominant representation of Culex pipiens/Cx. torrentium (42.36%), Aedes vexans (36.65%)...
The concentrations of six elements (Ca, Mg, Zn, Cu, Pb and Cd) in the eggshells of breeding red-crowned cranes (Grus japonensis) in China’s Zhalong Wetland were examined. Two macronutrients, namely, Ca and Mg, were predominant in the eggshells, with corresponding concentrations varying from 127 g kg−1 to 323 g kg−1 and 0.33 g kg−1 to 5.51 g kg−1 (dry weight, dw), respectively. The Cu and Zn contents...
This paper delivers molecular biological study of antimicrobial resistance in clinical isolates of Campylobacter spp. in Slovakia. During the year 2015 a total of 828 Campylobacter strains collected from five regions in Slovakia were examined for resistance to ciprofloxacin (CIP), tetracycline (TET), erythromycin (ERY) and ampicillin with sulbactam (SAM). The highest incidence of Campylobacter resistance...
The best duration of cold treatment for germination of Saxifraga aizoides and S. paniculata was investigated comparing seeds collected from Alpine and Apennine populations. For S. aizoides seeds of both provenances,the highest germination was obtained after 12 weeks of cold treatment, and Apennine seeds showed the best performance. For S. paniculata, the effect of cold treatment differed greatly in...
