1-, in info.json: change 
  "factorio_version": "0.15",
 to 0.16 
2- in each file of the prototype folder (even the one inside folders)
for each appearance of  icon = "adresse of an image",
add this line 
icon_size = 32,
exemple: 
type = "item",
    name = "algae-farm",
    icon = "angelsbioprocessing/graphics/icons/algae-farm.png",
    icon_size = 32,
    flags = {"goes-to-quickbar"},
    subgroup = "bio-processing-buildings",
    order = "a[algae-farm]",
    place_result = "algae-farm",
    stack_size = 10,if you do right, you shouldn't have any problem
I use wordpad for the json file edit and LUAEDIT for the lua files:)
this should allow you to play bioproccessing while waiting the official update:)
