Cotton, the king of natural fibres is mainly cultivated for its lint which is the most sought after textile fibre till date due to its inherent ecofriendly and comfort characteristics. It is also one of the important cash crops of many of the Afro-Asian countries like India, Iran, Egypt, Sudan, Uzbekistan, Tanzania, etc. and plays a major role in their economic development. However, of late, co...
This paper describes a microfluidics-based workflow for genetically targeted isolation and cultivation of microorganisms from complex clinical samples. Data sets from high-throughput sequencing suggest the existence of previously unidentified bacterial taxa and functional genes with high biomedical importance. Obtaining isolates of these targets, preferably in pure cultures, is crucial for adva...
This paper deals with the biosynthetic capacity for ochratoxin A (OTA) production by Aspergillus ochraceus E'G isolate derived from A. ochraceus CBS 108.08 strain, during 2007. Preliminary analysis of fungal potential for the production of OTA were performed according to the modified method of F i l t e n b o r g et al. (1983). Toxin production was tested in the following liquid media: (i) gluc...
Lactococcus lactis is highly efficient probiotics microorganism with wide range of benefits on human health. This study was conducted to design and establish industrial platform for high cell density cultivation of this novel probiotic strain, L. lactis (WICC-B25). During bioreactor cultivation of lactic acid bacteria in industrial scale, there are two main problems during process namely: low c...
BACKGROUND AND AIMS The wild progenitors of the Near Eastern legumes have low germination rates mediated by hardseededness. Hence it was argued that cultivation of these wild legumes would probably result in no yield gain. Based on the meagre natural yield of wild lentil and its poor germination, it was suggested that wild Near Eastern grain legumes were unlikely to have been adopted for cultiv...
Natural killer (NK) cells are a promising tool for the use in adoptive immunotherapy, since they efficiently recognize and kill tumor cells. In this context, ex vivo cultivation is an attractive option to increase NK cells in numbers and to improve their antitumor potential prior to clinical applications. Consequently, various strategies to generate NK cells for adoptive immunotherapy have been...
On base of stock-breeding and poultry wastes the cheap nutrient media for cultivation and production of biomass of phototrophic bacteria have been developed. Cultivation of purple nonsulfur bacteria Rhodobacter sphaeroides together with Bacillus megaterium in mixed culture has been succeeded in high biomass yield. The obtained biomass was distinguished with rich contents of biologically active ...
For cultivation of Mycobacterium ulcerans from clinical specimens, we optimized the release of bacteria from swabs, as well as decontamination and cultivation on supplemented medium. Nevertheless, the proportions of positive cultures, 41.7% (5/12) for fine-needle-aspiration (FNA) samples and 43.8% (49/112) for swab samples, were lower than those we have previously observed for excised tissue sp...
The efficient use of water resources, soil, and climate parameters as the main pillars of plant sustainable production requires land suitability evaluation for each crop and area. This research was conducted to evaluate land suitability for walnut cultivation in Iran using geographic information system (GIS). For this purpose, the climate data obtained from 375 synoptic stations of Iran, the ge...
Determining the cultivation crops area is important for properly supplying crops. The aim of this study was mapping the cultivation area crops in Chadian city for spring and summer during 2015 by using the time series data of the Landsat 8 satellite of OLI imagery. At first, the under cultivation area was determined by setting a low threshold in the marginal pixels of the agricultural rain fed ...
