The potentials of production of biogas from constructed wetland macrophytes

This study investigated the potential of biogas production from three (3) constructed wetland macrophytes: Water hyacinth (WH), cattail (CT) and Cyperus papyrus (CP). The digesters used had capacity of 0.22 cm3 each. They were operated under anaerobic conditions with organic loading rate (ORL) of 0.2 kg VS/m3.day and hydraulic retention time (HRT) of 5 days. Observations were made for a period of 128 days. The results...

Alkaline hydrolysis effect using NaOH on sugarcane bagasse from urban centers for ruminants

The aim of this study was to evaluate the alkaline hydrolysis of chemical composition of sugarcane bagasse from urban centers. The experimental design was completely randomized design in split plots (5×4), composed of five application levels (0, 1, 2, 3 and 4%) and four NaOH exposure periods (24, 48, 72 and 96 h) in four replicates. Dry matter, ash, neutral detergent fiber, acid detergent fiber, cellulose and...

Somatic embryogenesis and plant regeneration in popcorn (Zea mays L.) inbred lines

The objective of this study was to evaluate the production of embryogenic calluses and plant regeneration of seven popcorn inbred lines (Zea mays L.) in order to identify lines for further transference of genes to a generation of transgenic plants. The N6 medium with supplementation was used to induce calluses in immature embryos, and supplemented MS medium was used to stimulate plant regeneration of P11, P12, P15 and...

Synergistic antibacterial effect of Lepidium sativum and Coriandrum sativum against standard and drug resistant clinically isolated pathogenic bacteria

Emerging and increasing resistance to antibiotics has become a threat to public health globally. Spices and herbs are considered as rich source of bio-active antimicrobial compounds. Thus the aim of this study was to assess the antibacterial effect of Lepidium sativum and Coriandrum sativum seed extracts and their synergistic action against some selected pathogenic bacteria; namely: Klebsiella pneumoniae, Staphylococcus...
