Comparison of Satellite Derived Rainfall Estimations: CMORPH, IMERG and GSMaP with Observed Precipitation

引用

American Journal of Climate Change 2021年第4期10卷 407-421页

作者： Deepa Roy Sharmin banu Department of Mathematics Jashore University of Science and Technology Jashore Bangladesh

Being largely dependent on agriculture, the overall development and water resource management of Bangladesh are greatly influenced by the accurate estimation of precipitation. Different satellite derived precipitation products, covering a large area, are very useful for rainfall estimation. In this study, three different satellite precipitation datasets namely Climate Prediction Center MORPHING (CMORPH), the global Satellite Mapping of Precipitation (GSMaP), and the Integrated Multi-satellitE Retrievals for GPM (IMERG) daily data are spatially analyzed and compared with the observed rainfall data from 20th May 2020 to 21st May 2020. It is observed that the satellite products matched well with the observed data set but the amount varied. Also, the spatial distribution of CMORPH and GSMaP with the observed precipitation is represented for 02 May 2019.

Genetic variability of Aspergillus terreus from dried grapes

引用

Advances in Bioscience and Biotechnology 2010年第4期1卷 345-353页

作者： banu Narasimhan Madhivathani Asokan 不详

RAPD was used to examine the genetic variability among five isolates of Aspergillus terreus spp.. Two random primers were selected for the RAPD assay PG01–5’ CAGGTGTTGC 3’ and PG02–5’ CTGGACAGAC 3’ (Progen Technologies). The characterization of Aspergillus terreus species have been mostly applied on the basis of morphology, phenotype and physiology. DNA Polymorphisms are based on differences in DNA sequences and have advantages over protein polymorphisms. But morphological characterization besides molecular tools will remain a basic and powerful key in the identification of Aspergillus terreus species. The objective of the present study was to isolate the fungal contaminants from dried grapes and compare the genomic profile of the Aspergillus terreus speices isolated from the dried grapes, through RAPD analysis. In the present study with primer PG 01 four different discriminations was there among the A. terreus isolates. There was a homology of genotype between the isolates 1 & 3. And with primer PG 02 four different discriminations were there and there was a homology between 1 & 3. The predominant type was type I in primer I & II. The other isolates belonged to 2, 3 and 4. No similarity was detected for isolates 3, 4 and 5 indicating great genomic diversity of A. terreus.

Taxol as chemical detoxificant of aflatoxin produced by aspergillus flavus isolated from sunflower seed

引用

Health 2010年第7期2卷 789-795页

作者： Narasimhan banu Johnpaul Muthumary 不详

Aflatoxins are the potent toxic, mutagenic, heterogenic and carcinogenic metabolites produced by species of A. flavus and A. parasiticus. In the present study, an attempt has been made to prevent aflatoxin production using an anticancerous drug taxol. Taxol (Paclitaxel) is a well known drug for its anticancerous property mainly to treat breast and ovarian cancers. It was obtained from Taxus brevifolia and it was also obtained from the endophytic fungi present in Taxus brefivolia [1]. Therefore, this drug is specifically selected to screen its activity on the control of A. flavus and AFB1 production at various concentrations. Among the 6 concentrations used, 3 μg of taxol was found to be suitable to control the growth and AFB1 production. The content of AFB1 found at this concentration was 6 ppm by TLC and 6.3 ppm by HPTLC. The complete elimination of AFB1 might require higher concentrations of taxol.

DNA fingerprinting of Bacillus cereus from diverse sources by restriction fragment length polymorphism analysis

引用

Advances in Bioscience and Biotechnology 2010年第2期1卷 136-144页

作者： Swarnakaran Hemalatha Narasimhan banu 不详

Bacillus cereus is an opportunistic pathogen causing food poisoning manifested by diarrhoeal or emetic syndrome. It is closely related to animal and human pathogens Bacillus anthracis and the insect pathogen Bacillus thuringiensis. In the present study, antibiotic resistance, heavy metal tolerance &molecular typing of Bacillus cereus from diverse sources such as soil, sewage water, air, fresh water, sea water and milk were studied. Bacillus cereus resistant to Penicillin (10 units/ml) and Amoxycillin (10 µg/ml);sensitive to Cobalt and Mercury even at 1 mM concentration were determined. All the isolate had plasmid ranging in number from 3-5 and their molecular weight ranged from 3.0 kb-2.0 kb. Plasmid DNA band specific to 6,557 bp has been found in Bacillus cereus isolated from sewage water, air, fresh water, sea water and milk.

Enumeration of microbial contaminants in sachet water: a public health challenge

引用

Health 2010年第6期2卷 582-588页

作者： Narasimhan banu Himabindu Menakuru 不详

Accessibility and availability of fresh clean water is a key to sustainable development and essential element in health, food production and poverty reduction. In the present study, we have collected water sachet containing CM/L number and they were analysed for physical and bacteriological nature. The organisms isolated in this study were Proteus mirabilis, Klebsiella pneumoniae, Pseudomonas vesicularis and Pseudomonas aeruginosae. The harmful effects of these isolates were evidenced by antibiotic resistance, heavy metal tolerance and antibacterial activity. They were resistant to the antibiotics like amoxiclav, methicillin, chloramphenicol and streptomycin. They showed tolerance to the heavy metals at 5 mM conc. except for lead. For antibacterial activity, they were tested against human pathogens Klebsiella pnemoniae, Proteus mirabilis, Micrococcus leuteus and Salmonella paratyphium. But at the same time these organisms could be exploited for the industrial production of amylase, protease and cellulase.
