Batch fermentation of Penicillium chrysogenum, MTCC 5108 was carried out using potato dextrose broth medium prepared in seawater: distilled water (1:1). Biomass as dry weight was determined by gravimetric analysis. Citrinin, the main secondary metabolite, is produced in large quantities during the stationary phase of growth. The yield amounted to approximately 530 mg l. After optimization of cu...

Three different Aspergillus Niger MTCC strains (872, 1785 and 2208) were used for the production of chitosan. Multivariate growth mediums in varying incubation periods were analyzed for the production. The produced chitosan was characterized by its physical appearance, moisture content (by means of gravimetric method), percentage of ash and solubility (through the Association of Official Agricu...

Considering the serious health hazards of air pollutants from automobiles, the present study was aimed to estimate the genotoxic/tumor inducing potential of three soil samples collected from junctions of Bus stand (BS), Crystal (CT) and Railway station (RS) of Amritsar, Punjab (India) using Allium cepa root chromosomal aberration assay (AlRCAA) and potato disc tumor assay (PDTA). The genotoxic ...

Naive mated female cabbage looper moths, Trichoplusia ni Hübner, responded in a flight tunnel to potted potato plants ( Solanum tuberosum ). Percentages of moths attracted to uninjured potato plants, mechanically-damaged potato plants, and potato plants treated with regurgitant from larvae of the Colorado potato beetle, Leptinotarsa decemlineata Say, were similar, indicating no effect of plant ...

A nationwide survey was performed to investigate the current incidence of viral diseases in Korean sweet potatoes for germplasm and growing fields from 2011 to 2014. A total of 83.8% of the germplasm in Korea was infected with viruses in 2011. Commercial cultivars that were used to supply growing fields were infected at a rate of 62.1% in 2012. Among surveyed viruses, the incidence of five Poty...

Medicinal plants are valuable and used for the synthesis of numerous drugs. Indigenous plants are traditionally used against various ailments. Present work is based on the research conducted on methanolic crude plant extracts of three medicinal plants of family solanaceae i.e. leaves of Datura inoxia Mill., Withania somnifera (L.) Dunal and Solanum surrattense were screened to investigate the b...

Purpose: To investigate the antibacterial and antitumor activities of the aerial parts of 8 different Turkish endemic plants (Phlomis russeliana, Phlomis armeniaca, Astragalus brachypterus, Astrantia maxima, Ptilostemon afer, Senecio castagneanus, Echium orientale and Arum euxinum). Methods: Two different bioassays were performed to evaluate the antibacterial and antitumor activities of the end...
