Characterization of microbial degradation of oxytetracycline in river water and sediment using reversed phase high performance liquid chromatography
The fate of oxytetracycline (OTC) in river water and sediment and control experiments was investigated. A high-performance liquid chromatography (HPLC) separation and identification method was used to separate, identify and quantify OTC and its major degradation products. Minimum degradation of OTC was observed in control experiments. Non microbial degradation observed up to day 26 contributed slightly above 20% of the...

Comparison of fatty acid profile of wild and farm reared freshwater prawn Macrobrachium rosenbergii (De Man) brooders for broodstock diet formulation
Fatty acid profiles of midgut gland (MG), ovary and eggs of Macrobrachium rosenbergii of wild and farm reared brooders indicate a significant variation of their components during the sexual maturation and spawning. In both groups, major fatty acids found in the chosen tissues were 14:0, 16:0, 18:0, 18:1n-9, 18:2n-6, 18:3n-3, 20:4n-6, 20:5n-3 and 22:6n-3. Of these, saturated fatty acids dominate over the mono-unsaturated...

Utilization of sweet potato starches and flours as composites with wheat flours in the preparation of confectioneries
Freshly harvested roots of sweet potato variety TIS 87/0087 were processed into flour and starch using standard methods. Blends of Wheat and sweet potato composite flour was developed in the ratios 80:20, 70:30, 60:40 and 50:50. Also, blends of wheat and sweet potato starch were developed in the ratios 80:20, 70:30, 60:40 and 50:50. Whole sweet potato flour and starch were also included where 100% wheat flour was used...

Screening model for indolocarbazole-producing microorganisms by molecular probe combined with high performance liquid chromatography (HPLC) method
Indolocarbazole (ICZ) alkaloid constitutes a group of natural products which manifested powerful biological activity, especially anticancer. However, it was laborious to find ICZs-yield organism when anticancer activity was adopted as selection target. The specificity of 6 primer pairs was detected and the results revealed that primer rebBN1/rebBC1 possessed preferable specificity because indolocarbazole-producers DNA...

Identification and characterization of putative conserved IAM-hydrolases in developing rice grains
Indole-3-acetamide (IAM) pathway was proposed to produce indole-3-acetic acid (IAA). This pathway was proven to be functional in many species of bacteria and expected to operate in plants based on the identification of IAM and IAM-hydrolase (AMI) activity in certain plant species. Available putative AMI sequences from a wide array of monocot and dicot plants were identified and the phylogenetic tree was constructed and...

The effects of storage conditions on the viability of enteropathogenics bacteria in biobanking of human stools: Cases of Yersinia enterocolitica, Salmonella enterica Typhimurium and Vibrio cholerae O: 1
Long-terms recoverability of enteropathogens is necessary for future epidemiological studies to screen stool samples when conditions do not permit immediate processing. The aim of this study was to determine the viability and the recoverability of three enteropathogens bacteria (Yersinia enterocolitica, Vibrio cholerae O: 1 and Salmonella enterica Typhimurium) artificially contaminated at 107 CFU/ml in human stool...

Application of molecular markers to find out classificatory determinants of rice (Oryza sativa L.)
The present communication is aimed to find out determinants of molecular marker based classification of rice (Oryza sativa L) germplasm using the available data from an experiment conducted for development of molecular fingerprints of diverse varieties of Basmati and non Basmati rice adapted to irrigated and aerobic agro-eco systems. The distance-matrix based dendrogram was developed following UPGMA method that grouped...

Oyster mushrooms (Pleurotus) are useful for utilizing lignocellulosic biomass
This review shows the biotechnological potential of oyster mushrooms with lignocellulosic biomass. The bioprocessing of plant byproducts using Pleurotus species provides numerous value-added products, such as basidiocarps, animal feed, enzymes, and other useful materials. The biodegradation and bioconversion of agro wastes (lignin, cellulose and hemicellulose) could have vital implication in cleaning our environment....
