Synteny (co-linearity) in some cereal crops genomes as revealed by amplified fragment length polymorphisms (AFLP), simple sequence repeats (SSR) and inter simple sequence repeats (ISSR) markers
Genomes of barley, maize, rice, wheat and sorghum were characterized based on three different mole-cular markers based on DNA sequence namely; Amplified Fragment Length Polymorphisms (AFLP), Simple Sequence Repeats (SSR) and Inter Simple Sequence Repeats (ISSR) markers. Five AFLP primer combinations were used for fingerprinting six cultivars which belongs to barley, rice and wheat cultivars leading to the...

Magnetic-time model for seed germination
Germination of seed depends on several physico-chemical factors like temperature, water potential, light, nitrate content, smoke, electric field and magnetic field. In the present work, effect of static magnetic field on black-gram seeds (Cicer arietinum L.) was described. Seeds of C. arietinum L. were exposed in batches to static magnetic fields of 0 to 226 mT strength in steps of 50 mT (approximately)...

Decolourization and degradation of azo Dye, Synozol Red HF6BN, by Pleurotus ostreatus
The present paper focuses on the use of fungus, Pleurotus ostreatus, to decolorize and degrade azo dye, Synazol Red HF6BN. Decolorization study showed that P. ostreatus was able to decolorize 96% Synazol Red HF6BN in 24 days. It was also found that 94% Synazol Red HF6BN containing dye effluent was decolorized by P. ostreatus after 30 days of incubation at room temperature. The enzyme exhibited highest...

Acute toxicity assessment of crude lead-extract from electronic waste materials in Nigeria
Lead, with its toxic emission and pollution, is one of the hazardous chemical components of electronic wastes (e-wastes) rapidly generated in developing countries. This study assessed the environmental health effects of crude lead extracted from e-wastes materials, as determined by its acute toxicity (rat, oral). Diluted HNO3 and hot concentrated HCl tests were used to confirm the presence of lead in the...

Specific aminopeptidases of indigenous Lactobacillus brevis and Lactobacillus plantarum
Lactic acid bacteria play an important role in milk coagulation and cheese ripening. To select strains showing interesting industrial features, two indigenous lactobacilli (Lactobacillus brevis and Lactobacillus plantarum) were studied for aminopeptidase activity. Cell and cells free extract were tested for leucyl aminopeptidase activity on the chromogenic leucyl-p-nitroanilide substrate. Intracellu-lar and...

Evaluation of haematological and plasma biochemical effects of aqueous extracts of Parkia biglobosa seeds in rats
The effects of sub-acute exposure to aqueous extract of Parkia biglobosa seeds on haematology and plasma biochemical parameters were studied. Twenty eight male Wistar albino rats were orally ingested with 0, 200, 400 and 800 mgkg-1 dose of the extract for 21 days and were sacrificed. Haematological parameters were assessed: red blood cell counts, haematocrit and haemoglobin concentration significantly...

Screening of in vitro derived mutants of banana against nematodes
Investigations were carried out to screen the in vitro derived mutants of banana cv. Robusta (Caveidish- AAA) and Rasthali (Silk- AAB) by using certain bio-chemical parameters including some enzyme activities. The mutants tested were Ro Im V4 6-1-1, Ro Im V4 6-1-2, Ro Im V4 6-2-1, Si Im V4 10-5-3, Si Im V4 6-2-5 along with respective susceptible checks (Robusta and Rasthali),...

Efficacy of some antibacterial agents against Streptococcus mutans associated with tooth decay
Isolation of Streptococcus mutans was achieved from 79.3% of total positive culture of tooth decay cases. Testing of various extracts of Punica grantum (pomegranate), red and white fruit juice, fruit crust and three tooth pastes (Signal-2, Close-Up and Sinan) with comparison to standard antibiotics were carried out in this study. The highest diameter of inhibition zone was recorded for 1000 mcg/ml of fruit...

New record of stored product pest Lepinotus reticulatus (Psocoptera: Trogiidae) from China: Identification through scanning electron microscopy and DNA barcode
The parthenogenetic psocid Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae) is regarded as the common stored product pest in the world. This species has been identified as a new record in People's Republic (P.R) of China in this study. It was found in a sample of rice sweepings at grain storage in Lijiang, Yunnan, 2010. Decisive morphological characteristics of this new record species were...

Growth responses of Escherichia coli and Myxococcus xanthus on agar gel substrates with different levels of stiffness
Bacteria colonize surfaces responding to the physicochemical properties of substrates. A systematic study was carried out with growing single bacterial colonies on the surface of agar media to decipher the interaction between bacterial growth and substrate stiffness. We investigated the growth kinetics of wild-type Escherichia coli, non-motile E. coli, and Myxococcus xanthus, cultured on semi-solid agar...
