Two ethanol fermenting Saccharomyces cerevisiae were isolated from date juice and grapes and grown in YEPD medium. They were characterized for alcoholic fermentation using sugarcane molasses and their growth conditions were optimized with respect to pH and sugar concentration. Results revealed a temperature of 30ºC, pH 6.0 and 6.5% sugar concentrat...

In view of the anticipated shortage of the traditional supplies of fossil fuels, there is a great deal of interest in the production of ethanol as an alternative biofuel in recent years. The main objective of this research work was to isolate and characterize stress tolerant, high potential ethanol producing yeast strains from various fruit peel. T...

Introduction Water-borne diseases constitute a major health burden in Bangladesh. The objective of this study was to assess the overall quality of mineral water samples that obtained from different shops of Dhaka city. Material and Methods To achieve the above-mentioned objective, methods of heterotrophic plate count (HPC) and total coliform count...

Objective Halotolerant bacteria have multiple uses viz. fermentation with lesser sterility control and industrial production of bioplastics. Moreover, it may increase the crop productivity of coastal saline lands in Bangladesh by transferring the salt tolerant genes into the plants. The study focused on the isolation and identification of the halot...

Background: The requirement of an alternative clean energy source is increasing with the elevating energy demand of modern age. Bioethanol is considered as an excellent candidate to satiate this demand. Methods: Yeast isolates were used for the production of bioethanol using cellulosic vegetable wastes as substrate. Efficient bioconversion of ligno...

Gulshan Lake is an urban waterbody in the most exclusive area of Dhaka city, which is confronting a heavy load of pollution by anthropogenic activities. Prior studies were reviewed to analyze the trends of pollution. Rise of ammonia (eutrophication), lack of dissolved oxygen, and toxic heavy metals (as Pb, Cr, Cd, etc.) increase are the leading fac...

p align="justify">Cancer vaccination projects are on trial worldwide and the results are far-off being a remarkable success. Albeit, thousands of clinical trials are taking place, only a several of those are producing a significant result to increase the survival rate of the patients. Four vaccines (Human papillomavirus - HPV vaccines, Hepatitis B...

Textile wastewater contains large quantities of organic and inorganic compounds, which cause toxic and hazardous pollutants in the environment. Efficacy, efficiency and feasibility of the biological treatment method using macrophytes and algae were investigated, and various physicochemical parameters (TSS, TDS, pH, color, EC, DO, BOD, COD and metal...

Alcohol production from vegetable peels by yeast isolates SC1 and DJ1 at pH 6. Media pre-treated with Bacillus subtilis

Alcohol production from vegetable peels by yeast isolates SC1 and DJ1 at pH 6. Media without Bacillus subtilis pre-treatment

Introduction Mango juice has always been considered as a delicious, nutritious popular drink, but processed juice may not always be safe due to chemical and microbial risks. Determination of physicochemical and microbiological qualities of some packed mango juices of Bangladesh will help consumers to know the present scenario. Material and Methods...

Bioethanol obtained from microbial fermentation can replace conventional fossil fuels to satisfy energy demand. In this respect, a fermenting isolate of Saccharomyces cerevisiae, obtained from date juice, was grown in YEPD medium as a part of a previous published research project. In this study, the isolate was tentatively characterized for alcohol...

The impact of sea-level rise in South Asian coastline is significant. A huge portion of mangrove forest, named Sundarban, is threatened and predicted to be extinct before 2100s. The valuable flora and fauna will be a loss, along with it. Increased salinity also exacerbated the survival condition of flora and fauna. The severe impact on human popula...

In view of the anticipated shortage of the traditional supplies of fossil fuels, there is a great deal of interest in the production of ethanol as an alternative biofuel in recent years. The present study describes the search for potential yeast isolates from various fruit peels capable of producing ethanol. The main objective of this research work...

Plant regeneration heavily depends on the basal media factor. Recent studies showed the potential role of Driver and Kuniyaki Walnut (DKW) medium as an alternative to popular MS medium. In these studies, DKW distinctly depicted superiority over MS medium in terms of multiple shoot induction and callus mediated shooting of C. ternatea and B. austral...

Background and Objective: Clitoria ternatea is a local, valuable medicinal plant containing active major phytochemical compounds. Aim of this study was to establish an in vitro micropropagation protocol to produce C. ternatea at large scale. Materials and Methods: Cotyledonary nodal segments and cotyledons from aseptic seedling were used as explant...

Background: The occurrence of breast Cancer is a rising concern in Bangladesh. A hospital based case control study was conducted. Methodology: A nationwide representative sample of 100 out of 115 cancer patients aged 20 or older was interviewed at NICRH to provide information on awareness of the risk factors of breast cancer causes in Bangladeshi...

Natural water is being processed by the Reverse Osmosis purification system in the different area of Bangladesh for drinking purposes. Most of the water processing company is being filled the 500 mL, 1000 mL, 2000 mL and 5000 mL bottles with this processed water and being sold these widely in the different markets of Bangladesh. But the dissolved m...

Background/Objectives: Cestrum nocturnum L. a night Blooming jasmine belongs to Solanaceae family widely circulated all over tropical as well as subtropical areas of the World. It is mainly popular for ornamental fragrant flowering and hedge plant but also sometimes for traditional medicinal purpose. Due to strongest smelling characteristics of the...

The alternative fuels are expected to satisfy the progressive demand for energy on the wake of the negative effects of fossil fuel on the atmosphere and resultant universal warming. In this study two ethanol fermenting Saccharomyces cerevisae were isolated from Palm juice and Raisins. Method/Statistical Analysis: Both isolates were grown in Yeast e...

A high alkaline protease producing bacterial strain was isolated and identified a local soil sample. The organism was gram positive and forms spore during adverse condition in the growth medium. After various tests it was suggested and the features agreed with the description of Bacillus subtilis. It was also identified as B. subtilis with 99.5% id...

Microbial production of ethanol is a very popular concept in respect of alleviating energy demand nowadays. In this regard, two fermenting strains of Saccharomyces cerevisiae were isolated from date-juice and grapes and grown in YEPD medium. They are characterized for alcoholic fermentation using sugarcane molasses and organic kitchen-wastes media....
