A review on the integrated agro-technology of papaya fruit
The aim of this review was first to explore the effect of different pre-harvest factors affecting the quality of papaya including genetic factors, climatic conditions, cultural practices on post-harvest quality of the papaya fruit. Post-harvest physiology of papaya in terms of its respiration, ethylene production and sensitivity and transpiration was reviewed. Post-harvest handling and factors affecting...

Isolation and characterization of resistant gene analogs in cassava, wild Manihot species, and castor bean (Ricinus communis)
Cassava, Manihot esculenta, is one of the major food crops in sub-Saharan Africa (SSA) providing the bulk of dietary calories to hundreds of millions of households. Two viral diseases, namely cassava mosaic disease (CMD) and cassava brown streak disease (CBSD) pose a serious threat to cassava production. The emergence of new virus species and strains that overcome the existing resistant/tolerant...

Genetic diversity analysis of stress tolerant rice (Oryza sativa L.)
Fourteen rice genotypes, composed of six salt tolerant, three submergence tolerant, two drought tolerant genotypes along with three high yielding genotypes, released from Bangladesh Rice Research Institute (BRRI) were used for genetic diversity analysis using 40 simple sequence repeats (SSR) markers. All of the used SSR markers were found polymorphic among the 14 rice genotypes. The amplicon size...

Ranavirus (family Iridoviridae) detection by polymerase chain reaction (PCR) in Chinese giant salamander (Andrias davidianus, Blanchard, 1871), China
A disease in farmed Chinese giant salamander (Andrias davidianus) was a common event, being an economically important threat for Chinese farms. Based on the clinical signs, epizootiology and pathogens belonging to the genus, Ranavirus was suspected as the possible etiology. Although in a cultured Chinese giant salamander (Andrias davidianus) farm in Hanzhong County, Shanxi Province, China, a...

Assessment of endophytic fungi cultural filtrate on soybean seed germination
Soybean seeds have high amount of isoflavones but its germination is often confronted with a variety of environmental problems resulting in low germination rate and growth. To overcome this in eco-friendly manner, we investigated the influence of cultural filtrate (CF) of gibberellins-producing endophytic fungi on soybean seed germination. Three endophytic fungi namely: Chrysosporium...

Identification of pesticide-degrading Pseudomonas strains as poly-β-hydroxybutyrate producers
Polyhydroxybutyrate (PHB) is an ecological promising substitute for polypropylene because it is biocompatible, biodegradable and can be produced by renewable sources. This study investigated PHB accumulation on pesticide-degradingPseudomonas. 14 strains of pesticide-degrading Pseudomonas isolated from subtropical lowland soil in southern Brazil were analyzed using optical microscopy. Lipid...

Characterization of Indian native isolates of Trichoderma spp. and assessment of their bio-control efficiency against plant pathogens
A study was intended to corroborate the positive relatedness of molecular and morphological characters with antagonistic ability of Trichoderma species. On the basis of morphological and cultural characteristics, the Trichoderma isolates were identified as T. virens (11 isolates), T. asperellum (15), T. harzianum (14) and T....

Biodegradation of phenol with immobilized Pseuodomonas putida activated carbon packed bio-filter tower
Comparative study on adsorption and simultaneous adsorption and biodegradation (SAB) of phenol using Pseuodomonas putida (MTCC 1194) in a biofilter tower packed with fresh granular activated carbon (GAC) or biological activated carbon (BAC) showed 37% higher breakthrough point in case of SAB. Maximum phenol degradation rate in case of SAB was 120 mg/L.h obtained at flow rate of 7.42 ml/min....

Trace metal concentration and freshness quality of preserved catfish (Clarias gariepinus)
The freshness quality of fish is altered by enzymatic and microbial activities, necessitating the application of fish preservation technology. This study assessed trace metals concentration and freshness quality of catfish (Clarias gariepinus)preserved by oven-drying, brining/oven drying and smoking. The fish were processed to average moisture contents of 15 ± 5%. Processed fish samples were...

Technological properties of maize tortillas produced by microwave nixtamalization with variable alkalinity
This research was conducted to determine the quality, physicochemical, textural, compositional, nutritional, viscoamylographic and sensory properties of maize tortillas produced with a Modified tortilla-making process (MTMP) of variable alkalinity (0.125, 0.25 and 0.5% Ca(OH)2 w/w) and compared to the commercial brand MASECAâ. In general, tortillas from MTMP showed higher pH, total color difference...
