Heterotrophic bacteria converts milk into curd.So it means it should be present in the curd.Isn't it harmful for our health when we consume it ?
Is there any machine available in the market that can let us see bacteria and virus present in the surrounding ?DrDu said:There are many strains of bacteria populating your gut and they are immensely important to your well being. One even speaks of the bacteriome of a person as the sum of bacteria living inside it. This is a hot spot of research these days and each day new illnesses are liked to changes in the bacteriome. The bacteria used in the production of curd, yoghurt etc. are all ubiquitous in our intestines and certainly not harmful.

I can't carry microscope everywhere.It needs to be something handy.DrDu said:An electron microscope.

One will be invented decades later.Drakkith said:There isn't anything you can carry around that will let you see viruses. They are simply too small. You can see various bacteria with an optical microscope, but that's not exactly going to fit in your back pocket either.
How does DNA sequencing let's you detect such things ?Ygggdrasil said:DNA sequencing doesn't allow you to see the viruses, but you can certainly detect them more easily than with a microscope and you get a lot more information (e.g. you wouldn't be able to determine the whether the virus resistant to a particular drug by looking at them in a microscope).
I still don't get how DNA sequencing helps in "detecting" microbes present around us.Do we have a kind of device that let's us view the genes of microbes present around us?Ygggdrasil said:You can also detect specific genes, for example, particular genes or mutations associated with drug resistance.
But the problem is I need to get the cells of microbes for which I would need an electron microscope.That's a pretty long process.Ygggdrasil said:One can sample an environment for cells of any type (human, bacterial, fungal, etc), extract the DNA from these cells, then prepare the sample for DNA sequencing (this involves adding "adaptor" sequences to the ends of the DNA so that it can be read by the sequencing machine). The samples are then applied to the sequencing machine. The machine first amplifies the DNA (makes many copies of the DNA) so that you can get a good signal-to-noise ratio in the measurements.
The purpose of this research is to investigate the potential negative effects of consuming curd contaminated with heterotrophic bacteria, as well as to understand the factors that contribute to the growth of these bacteria in curd.
Heterotrophic bacteria can adversely affect the quality of curd by causing spoilage, leading to off-flavors, bad odors, and changes in texture. They can also potentially produce harmful substances such as toxins and pathogenic bacteria.
The potential health risks include food poisoning, gastrointestinal infections, and other adverse health effects. These risks are especially high for vulnerable populations such as young children, elderly individuals, and those with weakened immune systems.
The growth of heterotrophic bacteria in curd is influenced by various factors such as temperature, pH levels, moisture content, and storage conditions. Contamination during the production process and improper handling and storage can also contribute to bacterial growth.
To reduce the potential harm, it is important to follow proper hygiene and sanitation practices during production, handling, and storage of curd. This includes maintaining proper temperature and pH levels, using clean equipment, and avoiding cross-contamination. Additionally, consumers can reduce their risk by ensuring they purchase curd from reputable sources and consuming it before the expiration date.
