Question

10 beneficial and harmful microorganisms in food

Answer 1

What is a microorganism?A microorganismis an organism that can be seen only with the aid of a microscope.They include bacteria, protozoans, algae, and fungi.Beneficial microorganismsproduce a favorable result. They are helpful and useful.Harmful microorganismsare likely to have a damaging result. They are often called germs.Bacteria—Harmful or Beneficial?Both!Read about Bacteria on page 16-17.Both!Read about Fungi on page 18-19.A fungus(fungi is the plural) is neither a plant nor an animal.Fungi—Harmful or Beneficial?Hidden Helpers in our BodyBillions of bacteria in our bodies live in our intestines—more than 100 different kinds! (There is enough bacteria in you to fill three coffee cups!)These bacteria help us digest our food to get nutrients.Other bacteria make vitamins to help keep us healthy and disease-free.Bacteria In the AirSome bacteria float in the air and land on us.The helpful ones leave behind substances that keep harmful bacteria off of our skin.Harmful bacteria on our skin can cause sores or pimples.Harmful bacteria on our hands can transfer to food when we handle it to eat it.This is why washing your hands is SO IMPORTANT!!Other bacteria enter our body when we breathe. They can get into the nose, mouth, throat, and chest. As always, some are good, and some are bad.Other ways Microorganisms are BeneficialCleaning WaterMaking MedicineMaking Cheese, Yogurt, and BreadClean Water... “Thank you, Bacteria.”To have clean drinking water, a process called filtering occurs.At a treatment center, the water filters through sand and stone to catch all the pieces of dirt in it.Then the water is exposed to living bacteria that eat or destroy any harmful substances that may still be found in the water.Medicine... “Thank you, Microlife.”Bacteria and fungi are grown in large tanks called bio-vats.In these bio-vats, the microlifefloat, grow, and feed in a watery liquid. When necessary, some of the liquid is taken from the tanks and medicine is made.For example, E. coli is a bacteria that can be made into a medicine called insulin. Insulin helps people that have a disease called diabetes.Penicillin is made from a fungus called Penicillium. Penicillin is used to make antibiotics that kill harmful bacteria.Yummy Food...“Thank you, Microlife.”Yeast in bread is what helps it to rise. Yeast is a fungus.Mold, another type of fungus, helps to flavor the different kinds of cheeses we eat.Bacteria that is put in milk changes the milk to be thicker and slightly sour. Yogurt bacteria helps our bodies get more nutrients from other foods we eat.Beneficial Bacteria—Example: ActiviaActivia yogurt from Dannon has a bacteria in it called Bifidus Regularis that is supposed to help regulate your digestive system.“There are as many as five hundred bacterial species in the colon alone, including bifidobacteria only available in Activia.”These bacteria are called probiotics“What are probiotics?Probioticsare living microorganisms that, upon ingestion in sufficient numbers, exert health benefits beyond basic nutrition.”Harmful Microorganisms...Mold.Some mold can be beneficial microorganisms (like the ones that make cheese), but some types of mold are also harmful and will make you sick if you eat them.Mold is a fungus.Leave out a piece of bread... watch how quickly mold will grow on the bread.
