The tobacco cutworm, Spodoptera litura (Fabricius) is a serious cosmopolitan pest that attacks several economically important crops such as maize, sorghum, chickpea, pigeon pea, cotton, and sunflower. It has developed resistance to most pesticides resulting in its continual outbreak. effect of caffeic acid on second instar larvae S. was evaluated by carrying out bioassays, nutritional assays, immune assays biochemical with phenolic acids. Bioassays carried showed growth inhibiting effects...

Abstract A 4-chloro-3-nitrophenol (4C3NP)-mineralizing bacterium, Pseudomonas sp. JHN was isolated from a waste water sample collected chemically-contaminated area, India by an enrichment method. utilized 4C3NP as sole carbon and energy source degraded it with the release of stoichiometric amounts chloride nitrite ions. Gas chromatography gas chromatography-mass spectrometry detected 4-chlororesorcinol major metabolite degradation pathway. Inhibition studies using 2,2′-dipyridyl showed that...

Microorganisms have developed several physiological adaptations to survive within extreme ecological niches including environments contaminated with heavy metals, pesticides, polycyclic aromatic hydrocarbons, and nuclear wastes.Microorganisms in habitat are potential source of "novel biomolecule(s)" such as whole microbial cells, extremozymes extremolytes, significantly required for environmental, industrial, red medical/pharmaceutical biotechnology.These novel biomolecule(s) valuable...

Seed oils of Gynandropsis gynandra, Impatiens balsamina, Celastrus paniculata, Embelia ribes and Mucuna pruriens were investigated for their anthelmintic property against Pheritima posthuma . Three concentrations (10, 50 100 mg/ml) each oil studied in a bioassay, which involved the determination time paralysis death worm. All exhibited moderate to significant activity. showed best activity both parameters. Piperazine citrate (10 was included assay as standard reference drug.

Eighteen bacterial strains, isolated from a waste water sample collected chemically contaminated site, Patancheru (17°32′N 78°16′E/17.53°N 78.27°E), India, were able to decolorize 4-chloro-2-nitrophenol (4C2NP) in the presence of an additional carbon source. These eighteen 4C2NP-decolorizing strains have been identified as members four different genera, including Bacillus , Paenibacillus Pseudomonas and Leuconostoc based on 16S rRNA gene sequencing phylogenetic analysis. Most bacteria (10)...

Tribulus terrestris L., commonly called puncture vine and gokhru, is an important member of Zygophyllaceae. The species highly in context to therapeutic uses provides active principles responsible for treatment various diseases also used as tonic. It widely distributed tropical regions India the world. However, status its genetic diversity remained concealed due lack research work this species. In present study, structure different populations T. from north was examined at molecular level...

A degradation pathway of 2-chloro-4-aminophenol (2C4AP) was studied in an Arthrobacter sp. SPG that utilized 2C4AP as its sole source carbon and energy. The initiated by a 2C4AP-deaminase catalyzed the conversion into chlorohydroquinone (CHQ) with removal ammonium ion. In next step, CHQ-dehalogenase dehalogenated CHQ to hydroquinone (HQ) cleaved γ-hydroxymuconic semialdehyde HQ-dioxygenase. also investigated sterile non-sterile soil microcosms using strain SPG. results show cells degraded...

The present study revealed the varied frequency of natural chromosomal abnormalities in 13 populations pertaining to 9 species genus Artemisia L. from different localities Himachal Pradesh (Western Himalaya). Intraspecific chromosome variability has been reported for first time on worldwide basis vestita (2n = 2x 36) and India A. macrocephala 18) scoparia 36). Besides, B-chromosomes have here nilagirica roxburghiana. Most show anomalous meiotic behaviour resulting cytomixis, stickiness,...

Abstract Helicobacter pylori ( H. ), the major cause of several gastric disorders has been recognied as a type I carcinogen. By virtue resistance developed by strains, currently used antibiotic based treatments rather demonstrate high failure rates. Hence, there is an emerging need for identification new targets to treat infection. Inosine-5′-monophosphate dehydrogenase (IMPDH) studied potential target Here, detailed enzyme kinetic study recombinant expressed inosine-5′-monophosphate Hp...

Wild fruits, directly or in combination with other foodstuff, are used by many people living the rural regions of tropical countries to address food and income insecurity. The composition wild fruits needs be analyzed compared traditional fruits. In present study, we investigated nutritional status two species (eight populations) Ziziphus mauritiana (ZM) Z. nummularia (ZN) from different locations Northwest India, which were denoted as ZM-1, ZM-3, ZM-11, ZN-4, ZN-5, ZN-10, ZN-13, ZN-14...

The review summarizes different bioinformatics tools used in studying the degradation of various xenobiotic compounds. Databases and Pathway Prediction Systems are key involved biodegradation. Several bio-degradative databases including EAWAG-BBD (Biocatalysis/Biodegradation Database), Plastics Microbial Biodegradation Database, ONDB (Organonitrogen Degradation Food risk component database (Food database, Aromadeg (Aromatic hydrocarbon Degrading OxDBase (A Biodegradative oxygenases), RHObase...
