Actinomyceter:
<\/strong>Actinomyceter kallas ofta f\u00f6r str\u00e5lsvamp. De reproducerar sig antingen med hj\u00e4lp av sporer eller med hj\u00e4lp av fragment av hyfer.
Utomhus f\u00f6rekommer Actinomyceter naturligt i jorden.
P\u00e5 byggnadsmaterial \u00e4r Actinomyceter mycket vanlig f\u00f6rekommande. Den avger jordk\u00e4llarlukt. Den \u00e4r vanligt f\u00f6rekommande n\u00e4r fuktskador uppst\u00e5r i eller i n\u00e4rheten av husets grundkonstruktion.<\/p>\n\n\n\n

R\u00f6tsvamp:
<\/strong>R\u00f6tsvamp har f\u00f6rm\u00e5ga att byta ner byggnadsmaterial. F\u00f6r att kunna etablera sig kr\u00e4ver den i regel mer fukt \u00e4n vad m\u00f6gel g\u00f6r. R\u00f6tsvampen tr\u00e4nger ocks\u00e5 djupare in i virket \u00e4n m\u00f6gel. Detta \u00e4r viktigt att k\u00e4nna till n\u00e4r man skall behandla med fungicid. D\u00e5 m\u00e5ste man v\u00e4lja ett medel som veden kan suga upp.
R\u00f6tsvamp ben\u00e4mns som Brunr\u00f6tesvamp eller Vitr\u00f6tesvamp.
<\/p>\n\n\n\n

Brunr\u00f6tesvampen bryter ner cellulosan men inte ligninet. D\u00e4rf\u00f6r brunf\u00e4rgas veden och tv\u00e4rg\u00e5ende sprickor bildas materialet.
<\/p>\n\n\n\n

Vitr\u00f6tesvampen bryter ner b\u00e5de cellusa och lignin. Veden blir vitaktig och l\u00e4ngsg\u00e5ende sprickor bildas i materialet.<\/p>\n\n\n\n

 
Brunr\u00f6tesvampen \u00e4r vanligast f\u00f6rekommande i fuktskadesammanhang. En av dessa, den \u00c4kta hussvampen, kan p\u00e5 mycket kort tid bryta ner veden. Genom sitt system av hyfer klarar den av att h\u00e4mta sitt vatten flera meter fr\u00e5n sj\u00e4lva v\u00e4xtplatsen. N\u00e4r \u00c4kta Hussvampen arbetar skapar den en sur milj\u00f6 f\u00f6r sig sj\u00e4lv. Detta g\u00f6r att den str\u00e4var efter att neutralisera surheten. Vanligast g\u00f6r den det med hj\u00e4lp av olika kalkk\u00e4llor. Vanligt \u00e4r att den anv\u00e4nder sig av kalken som finns i murstockar.<\/p>\n\n\n\n

Andra mycket vanligt f\u00f6rekommande Brunr\u00f6tsvampar \u00e4r:
K\u00e4llarsvampen och M\u00f6gelticka. K\u00e4llarsvampen nyttjar ocks\u00e5 kalk. I veden bildas kristaller av kalk vilket \u00e4r en bra ledtr\u00e5d vid identifieringen.<\/p>\n\n\n\n

I stolpar \u00f6ver och under jorden p\u00e5tr\u00e4ffar man ofta P\u00e5l-svampen. Den \u00e4r en vitr\u00f6tesvamp.<\/p>\n\n\n\n

P\u00e5lsvampen klarar av h\u00f6ga fuktkvoter men den kr\u00e4ver ocks\u00e5 mycket syre. En p\u00e5le i en grundkonstruktion kan st\u00e5 emot ett angrepp s\u00e5 l\u00e4nge den st\u00e5r under vatten men om grundvattnet sjunker kan den mycket snabbt bryta ner p\u00e5len.<\/p>\n\n\n\n

 
R\u00f6tsvamp vill ha lugn och ro f\u00f6r att utvecklas. D\u00e4rf\u00f6r h\u00e4nder tyv\u00e4rr inte alltf\u00f6r s\u00e4llan att den uppt\u00e4cks f\u00f6rst n\u00e4r det \u00e4r f\u00f6r sent. Vid angrepp av r\u00f6tsvamp m\u00e5ste man utreda och g\u00f6ra \u00e5tg\u00e4rder f\u00f6r att f\u00e5 bort fukten. Man b\u00f6r l\u00e5ta analysera vilken typ av svamp det r\u00f6r sig om. Dels d\u00e4rf\u00f6r att man m\u00e5ste sanera noggrannare om den \u00c4kta Hussvampen \u00e4r n\u00e4rvarande men ocks\u00e5 ur f\u00f6rs\u00e4kringssynpunkt.<\/p>","protected":false},"excerpt":{"rendered":"
