The effect of various carbon and nitrogen sources on cellulose production byAcetobacter lovaniensis HBB5 was examined. In this study, glucose, fructose, sucrose ethanol as source yeast extract, casein hydrolysate ammonium sulphate were used. Among the sources, glucose gave highest yield, followed by ethanol. Besides, among extract sulphate. In Hestrin-Schramm (HS) medium that contained 2% (w/v) 0.5% bacterial was 0.040 g/l (dry weight) after 7 days. Morphological view of A. strain bundle...

Abstract Primula is a plant genus which comprises about 400 species. It has been found in number of pharmacological studies that primrose extracts are rich saponins. Phenolic glycosides and saponins characteristic compounds for the Primula. In this study several flower from veris L. tested antibacterial activity decoction flowers antimitotic activity. Antibacterial was determined by well diffusion method Allium cepa used evaluating cytotoxicity. Decoction toxic on root length A. reduced...

The influence of the grinding and physical form diets on growth performance, gastrointestinal tract (GIT) development nutrient digestibility was studied in layer pullets from hatch to 112 d age. Diet formed a 2 × factorial with hammer mill screen sizes grind cereals (4 8 mm) forms (mash crumble). A total 864 1-day-old chickens were randomly assigned 1 4 treatment groups replicates (27 birds per replicate). Cumulatively, fed crumbles consumed less feed (P < 0.05) had better conversion ratio...

Abstract A thermophilic esterase producing bacterium ( Bacillus sp. 4), recently isolated from Alangüllü thermal spring in Aydın (Turkey), was analyzed using 16S rRNA and classified as Geobacillus HBB‐4, most closely related to BGSC W9A59 (0.70% sequence divergence) which belongs the newly described genus . The effects of several chemicals on activity thermostable HBB‐4 were examined. Among various metal ions tested, enhanced by Mn +2 Ni , but inhibited Hg Cu whereas Ca Mg Co had no effect....

ABSTRACT The mold flora of 50 dried fig samples consumed in Turkey was examined and the aflatoxigenic ones were determined. Among 127 fungi isolated, 74 Aspergillus, 24 Trichoderma, 16 Fusarium 13 Acremonium. Of isolates, 17 four them capable to produce aflatoxin, three which characterized as A. flavus one parasiticus. Aflatoxin production strains confirmed by high pressure liquid chromotography. effect UV irradiation on count aflatoxin quantity also tested. It found that led a decrease...

The extracellular amylase produced by Penicillium citrinum HBF62 was purified 18 folds using starch affinity chromatography. molecular weight of was estimated to be about 65 kDa by SDS-PAGE. temperature and pH for optimum activity the enzyme were 55°C 5.5, respectively. It thermostable between 27 60°C retained more than 50% after 24 h at these temperatures. found stable range 3.5 8.5. Km Vmax values soluble calculated 0.2 mg/ml 5000 U/mg protein, exhibited broad substrate specificity because...

In this study, the resistance of 83 strains lactic acid bacteria isolated from Turkish cheese, yogurt, kefir and boza samples to 6 antibiotics (gentamicin, tetracycline, chloramphenicol, erythromycin, vancomycin ciprofloxacin) was evaluated. The isolates were identified by 16S rRNA gene sequencing according BLAST comparisons with sequences in data banks, those showing highest similarities Enterococcus faecium (10), Lactococcus lactis subsp. Lactis Lactobacillus fermentum (6), plantarum...

Reaction of 1-phenyl-3-methyl-4-benzoyl-pyrazol-5-one and benzoyl hydrazide in refluxing ethanol gave N ′-[( Z )-(3-methyl-5-oxo-1-phenyl-1,5-dihydro-4 H -pyrazol-4-ylidene)(phenyl)methyl]benzohydrazide (HL 1 ), which was characterized by NMR spectroscopy single-crystal X-ray structure study. diffraction analyses the crystals revealed a nonplanar molecule, existing keto-amine form, with intermolecular hydrogen bonding forming seven-membered ring system. The reaction HL Co(II), Ni(II), Cu(II)...
