The term bacterial metropolis means that bacterium and fungi build life , like to how human being construct house , offices , and school . bacterium and fungi live in comparable social organisation , albeit on a much smaller scale and on every surface in the environment . In the past , human live in the open field without a cap over their head , divvy up with external accent factors such as rain , violent storm , or extreme high temperature . Therefore , humanity started build wooden barns to protect themselves , and today , we build skyscrapers . In this way , humanity can live safely as well as share noesis and experiences at the office or school . Bacteria and fungi live in interchangeable cities .
The growth and ontogenesis of biofilmBacteria are often the first dweller ; they seize themselves to a surface ( such as the inside of an irrigation system ) and create a ugly level to protect themselves . This stratum is mostly made up of sugars but also proteins , lipids , and minerals . Once settled , bacterium breed in the guck layer . Or , put forward differently , the metropolis enlarge , and the ‘ biofilm ’ grow . The biofilm can further develop by propagate a fate of the bacteria ( figure of speech 1 ) , just like kid leaving their parental home when they are adults . Thus , once biofilm is present , it will grow and spread exponentially ( Karygianni , Ren , Koo , & Thurnheer , 2020 ; Alotaibi & Bukhari , 2021 ) .
name 1 : The three stage of biofilm ontogeny . Phase 1 : Attachment of free - floating bacterium to the Earth’s surface . phase angle 2 : A biofilm is formed and uprise . Phase 3 : insularism and spread of bacteria to other surfaces ( Karaguler , Kahraman , & Tuter , 2017 ) .
Although biofilm is well resistant to external stressors , factor such as temperature , humidness , O levels , and turbulence still strike the growth and stableness of biofilm . For instance , a higher temperature increase biofilm ’s potential to grow and spread . to boot , greater turbulence ( like the menses of water ) creates more stress for bacteria , which is a stimulant for forming a thicker layer of biofilm . These bring up conditions are like to the surround in irrigation pipes .
The influence of nutrient waterOn top of this , minerals are added to the nutrient water for plants to optimize their wellness and developing . However , fertilizers are also beneficial for microorganisms in the biofilm . The minerals from fertilizers are used as food and reinforcement . The mineral act as scaffolding , making the biofilm stronger and more static ( fig 2 ) . This create it harder , but also more serious , to remove the biofilm . Once the scaffolds are reveal down , the bacterial city collapses , and tumid region of the biofilm become detached , which can make choked drippers . Therefore , it is essential to be mindful of the organization of biofilm in the irrigation arrangement and the necessity to forbid its formation .
shape 2 . Biofilm geological formation with and without the comportment of the mineral calcium . The result is shown after 3 and after 7 day of water flow ( Oppenheimer - Shaanan et al . , 2016 ) .
Constructive collaboration of fungus kingdom and bacteriaAside from bacteria , fungus kingdom also form biofilm structures . Fungi often attach to mature bacterial biofilm . enquiry has indicate that the hyphae of fungus are used by bacteria as a highway . The fungous structures serve as a transmitter for bacterium spreading and strengthen the formation of biofilm . Once fungi are part of the biofilm , the structure is more resilient and more difficult to slay .
Preventing and take away biofilmWith these threat , it is important to prevent the formation of biofilm . When it is already present , it is important to remove it to avoid problems during cultivation . Since biofilm is mainly composed of lettuce , it is important to expend a product that conk out down and take on these sugars . Claudia Weick of Intrahorti says : “ Often mathematical product based on Cl are used ; however , these do not come across this requisite . Intra Hydropure is a silver - chelate H hydrogen peroxide . This can tackle the biofilm . It evenly break down the biofilm , and the bacterium and fungus that are released are eliminate . This prevents transmission in plants and blocked drippers . ”
Intra Hydropure is a biocide specifically designed for usage in irrigation systems . The intersection is registered allot to the EU - BPR and is specifically provide for the removal of biofilm and disinfection . Claudia : “ By improving pee quality and reducing microbiological contamination , Intra Hydropure is a sustainable solvent for hygiene applications in horticulture . ”
