<p>For this purpose the same yeast Saccharomyces cerevisiae used for bread-making and commonly called brewer’s yeast, is used for fermenting malted cereals and fruit juices, to produce ethanol</p>
</li>
<li>
<p>Do you recollect the metabolic reactions, which result in the production of ethanol by yeast? Depending on the type of the raw material used for fermentation and the type of processing (with or without distillation) different types of alcoholic drinks are obtained</p>

<p>After Penicillin, other antibiotics were also purified from other microbes</p>

<p>Can you name some other antibiotics and find out their sources? Antibiotics have greatly improved our capacity to treat deadly diseases such as plague, whooping cough (kali khansi ), diphtheria (gal ghotu) and leprosy (kusht rog), which used to kill millions all over the globe</p>

<p>Have you ever wondered where this huge quantity of sewage or urban waste water is disposed off daily? This cannot be discharged into natural water bodies like rivers and streams directly - you can understand why</p>
</li>
<li>
<p>Before disposal, hence, sewage is treated in sewage treatment plants (STPs) to make it less polluting</p>

<p>Treatment of waste water is done by the heterotrophic microbes naturally present in the sewage</p>

<p>This treatment is carried out in two stages: image Primary treatment : These treatment steps basically involve physical removal of particles - large and small - from the sewage through filtration and sedimentation</p>
