The fermentability of a corn cob, acid-hydrolysed hemicellulose by Pichia stipitis was considerably improved by pre-treatment with Ca(OH)2. The total sugars utilized and ethanol yield for the untreated hydrolysate were 18% and 0.21 g/g, respectively, compared with 82% and 0.32 g/g respectively for the treated material. Adaptation of the yeast to the hydrolysate resulted in a significantly highe...

Expression of the yeast mitochondrial cytochrome b gene (COB) is controlled by at least 15 nuclear-encoded proteins. One of these proteins, Cbp1, is required for COB mRNA stability. Delta cbp1 null strains fail to accumulate mature COB mRNA and cannot respire. Since Delta cbp1 null strains lack mature COB transcripts, the hypothesis that Cbp1 also plays a role in translation of these mRNAs coul...

While evolution of coding sequences has been intensively studied, diversification of noncoding regulatory regions remains poorly understood. In this study, we investigated the molecular evolution of an enhancer region located 5 kb upstream of the transcription start site of the maize pericarp color1 (p1) gene. The p1 gene encodes an R2R3 Myb-like transcription factor that regulates the flavonoi...

a study was conducted to evaluate the effects of plant growth promoting rhizobacteria (pgpr) inoculants including four strains of azotobacter chroococcum, azospirillum lipoferum, a. brasilense and pseudomonas fluorescence on dry matter accumulation of late maturing maize(zea mays l.) hybrids, sc704, sc700 and a promising single cross b73×k18. a factorial experiment was conducted in research fie...

Microbial extraction of nickel from lateritic chromite overburden (COB), Sukinda by Acidithiobacillus ferrooxidans has been investigated in this work. In anoxic environment, A. ferrooxidans reduced the ferric iron in goethite [Fe(O)OH] mineral of COB by using elemental sulphur as electron donor. Nickel embedded in the complex goethite matrix of COB was successfully recovered by cumulative actio...

Salmonella enterica degrades 1,2-propanediol (1,2-PD) by a pathway that requires coenzyme B(12) (adenosylcobalamin; AdoCbl). The genes specifically involved in 1,2-PD utilization (pdu) are found in a large contiguous cluster, the pdu locus. Earlier studies have indicated that this locus includes genes for the conversion of vitamin B(12) (cyanocobalamin; CNCbl) to AdoCbl and that the pduO gene e...

A field experiment was conducted during Kharif season of 2022 at Crop Research Farm (CRF), Department Agronomy, SHUATS, Prayagraj (UP) to investigate the “Evaluation Maize (Zea mays L.) hybrids under agro-climatic conditions Prayagraj, U.P”. The treatments consists 18 hybids. laid out in Randomized Block Design with ten replicated thrice. significantly highest plant height (169.75 cm), number l...

Maize (Zea mays L.) is one of the most versatile emerging crops having wider adaptability under varied agro-climatic conditions. Globally maize Known as “Queen cereals” because it has highest genetic yield potential among cereals To find out best Genotype hybrids, a field experiment was conducted during kharif season 2022 at experimental Crop Research Farm, Department Agronomy, Naini Agricultur...

Plant cell shape is achieved through a combination of oriented cell division and cell expansion and is defined by the cell wall. One of the genes identified to influence cell expansion in the Arabidopsis (Arabidopsis thaliana) root is the COBRA (COB) gene that belongs to a multigene family. Three members of the AtCOB gene family have been shown to play a role in specific types of cell expansion...

This study was aimed to determine the genetic variance of several F2 population traits maize, broad heritability values and phenotypic correlations between yields other quantitative traits. The method used is experimental method. experiment designed in a randomized block design, with 6 replications. number treatments 4 populations, namely F2, Sinta Unram, hybrid NK212 NK7328. Each planted rows,...
