Microbiology Semester 2 Week 4

       Assalamualaikum and hi everyone... how are you all? I hope everyone will be fine as well... On Tuesday, before the microbiology class Dr Wan asked us to create one page in padlet to write down our progress about the video of fungi.  In microbiology, Dr Wan was taught us more about the microbial groups. Basically, microbial groups is based on size of population and not individual growth and also is interrelated with reproduction. Methods of microbial reproduction is binary fission, budding, fragmentation, formation of spores and sexual reproduction. Requirements for development of microbial community which is physical growth requirements and chemical growth requirements. Physical growth requirements are light, temperature, pH and water activity and osmotic pressure. Chemical growth requirements are water, carbon, oxygen, nitrogen, phosphorus and sulfur special growth factors and trace elements. 2 major nutritional which are source of energy and source of carbon. Development of microbial communities in a habitat is populations compete to occupy niches, each successful population plays a functional role and contributes to the maintenance of the community , first population to arrive have selective advantage, overtime, there may be population succession and microbial diversity is the higher the beder to stabilise a habitat; have overlapping niches and functions. Development of microbial communities is selection strategies, succession and  biofilms.

     

       On Friday, Dr Wan taught us about the aspects of biotechnology in microbial ecology. Basically, functions of microorganisms in microbial ecology is microorganisms as pollutants, microorganisms  as cause of pollution, microorganisms as indicator of pollution and microorganisms may reduce pollution. Biodegradable is all natural organic compounds and biodegradable if environmental conditions are favorable. Nonbiodegradable is recalcitrant and synthetic molecules which is some are toxic. Bioremediation is the use of living organisms to promote the degradation of environmental pollutants (artificially and increase the growth of naturally occuring microorganisms. Bioremediation is aarried out a biodegradation processes not at a desired rate a limiting physical or nutritional factors.
