Antifungal activity and preliminary phytochemical analysis of bark extracts of Moringa oleifera Lam.

The Chloroform, Ethyl acetate, Methanol and aqueous extracts of Moringa oleifera bark traditionally used in folkloric medicine for the treatment of various infections were investigated for their antifungal activity against 2 fungal strains viz., Rizopus stolonifer and Microsporum gypseum by disc diffusion method. The different extracts of the plant species reduced colony growth of both […]

Antimicrobial activity and antibiotic resistance of LAB isolated from Sudanese traditional fermented camel (Camelus dromedarius) milk gariss

Fourteen strains of Enterococcus species, 3 strains of Lactobacillus species and two strains of Streptococcus isolated from 6 different gariss samples collected from Kordofan and Khartoum production sites, Sudan were screened for antibacterial activity against Staphylococcus aureus ATCC 25923 and E.coli ATCC25922 and for their antibiotic resistance against 9 antibiotics. The results indicated that all […]

Ladybird beetles fauna of Hazara University, garden campus, Mansehra, Pakistan

Present study was carried out as a first documentation of lady bird beetles in Hazara division during 2011. A total of 300 specimens were collected from three sites i.e., residential area (205), administration area (24) and main campus (71) of Hazara University. Identification of these beetles showed that 7 different species in 6 genera belong […]

Shrub layer dynamics of Turkey-oak forest between 2002 and 2007 in North-Hungary. Síkfőkút LTER

At the Síkfőkút Project Long Term Ecological Research (LTER) area covered by a sessile oak – Turkey-oak forest (Quercetum petraeae-cerris). Similarly to other European countries an oak decline occurred in Hungary at the end of 1970’s. The oak decline resulted in an opening of the canopy; the canopy cover decreased from 80% (1972) to 36% […]

Biosorption of copper from wastewater by Bacillus subtilis in a packed bed bioreactor

The potential for copper (Cu2+) reduction in a fixed-film bioreactor system was investigated using a copper reducing bacterial species Bacillus subtilis. This work on the process of biosorption of copper from wastewater in a continuous-flow, fixed packed-bed bioreactor was conducted in a search for solution to the environmental problem caused by heavy metals. The Cu2+ […]

Allelopathic potential of Notholirion thomsonianum (D.Don) stapf

The present study was conducted to assess the allelopathic potential of Notholirion thomsonianum (D.Don) Stapf against Triticum aestivum by using extract of plant parts. The plant material was collected from swat and dried at room temperature (25 ̊C- 30 ̊C). Allelopathic potential was evaluated by conducting experiments in laboratory. The aqueous and hot water treatments […]

A Survey on the flora and the fauna of the Fereydunkenar International wetland for better conservation management

Fereydunkenar international wetland (registered in Ramsar Convention) covers 5427 hectares at the south of Caspian Sea in Mazandaran province. Identifying the district’s flora and fauna, a four-year survey was conducted in direct observation method; as a result of which a variety of species were recognized including trees(18), mammals(7), fishes(10), reptiles(6), amphibians(5) and birds(88). The trees […]

Chemical composition and in vitro antifungal activity of Zingiber officinale essential oil against foodborne pathogens isolated from a traditional cheese wagashi produced in Benin

The aim of the present work was to assess some antifungal activity parameters as mycelial growth inhibition, minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of Zingiber officinale essential oil from Benin against Aspergillus (flavus and tamarii), Fusarium (poae and verticillioides) and Penicillium (citrinum and griseofulvum) species isolated from traditional cheese wagashi. The chemicalcomposition […]

Effect of crude oil and simulated acid rain on the growth and physiology of Thaumatococcus daniellii

This research work was carried out to investigate the effect of crude oil and simulated acid rain (SAR) on the growth and physiology of Thaumatococcus daniellii. 24 seedlings were planted on soil with different concentrations of crude oil 0.5ml, 2.5ml, 5.0ml, 7.5ml, 10ml, 12.5ml, 15ml and 17.5ml, while soil without crude oil served as the […]

Physicochemical and microbial characterization of somberiro river in ahoada east local government area, Rivers State, Nigeria

A total of six water samples collected at three different stations from Somberiro River were analyzed for the physico – chemical and bacteriological parameters. The physico – chemical parameters recorded highest concentration in site A except in conductivity while Phosphate, Potassium and Nitrate were found higher in site C and site B recorded highest in […]
